Human Anatomy and Physiology for Pathology Courses

Human Anatomy:

Human Anatomy is the scientific study of the body’s structures, from the microscopic level (cells, tissues) to the macroscopic (organs, systems), focusing on form, location, and relationships between parts, essential for medicine and biology, often studied alongside physiology (how parts function). It’s divided into gross anatomy (visible to the naked eye) and microscopic anatomy (histology/cytology) and explores the body’s eleven major systems, like skeletal, nervous, and circulatory.

Key Branches & Approaches

Gross Anatomy (Macroscopic): Studying large structures without magnification, through dissection or imaging (X-ray, MRI).
Microscopic Anatomy (Histology/Cytology): Examining tissues and cells with microscopes.
Regional Anatomy: Organizing study by body areas (head, limbs, trunk).
Systemic Anatomy: Organizing by organ systems (e.g., nervous, digestive).
Radiological Anatomy: Using medical imaging (CT, MRI).

Major Body Systems

Integumentary: Skin, hair, nails (protection).
Skeletal: Bones (support, structure).
Muscular: Muscles (movement, posture).
Nervous: Brain, spinal cord, nerves (control, coordination).
Endocrine: Glands, hormones (regulation).
Cardiovascular (Circulatory): Heart, blood vessels (transport).
Lymphatic: Lymph nodes, vessels (immunity, fluid balance).
Respiratory: Lungs, airways (gas exchange).
Digestive: Stomach, intestines (nutrient absorption).
Urinary (Excretory): Kidneys, bladder (waste elimination).
Reproductive: Organs for reproduction.

Human Physiology:

Human physiology is the science of how the human body works, studying its mechanical, physical, and biochemical functions, from cells to organ systems, to maintain a stable internal environment (homeostasis) and respond to challenges like exercise, stress, or disease. It examines systems like nervous, circulatory, respiratory, and digestive, understanding how they interact to keep the body alive and healthy, forming the basis for modern medicine and performance science.

Core Concepts

Homeostasis: The body’s ability to maintain stable internal conditions (like temperature, pH, blood sugar) despite external changes.
Levels of Organization: From molecules and cells to tissues, organs, organ systems, and the whole organism.
Interconnected Systems: Organ systems (e.g., nervous, endocrine, cardiovascular, respiratory) work together, often coordinated by the neuroendocrine system, to achieve body functions.

Key Systems Studied

Nervous System: Control center, processing signals, thoughts, movements (neurons).
Endocrine System: Uses hormones to regulate body processes like blood pressure, growth.
Cardiovascular/Circulatory System: Heart, blood vessels; transports oxygen, nutrients, waste.
Respiratory System: Lungs, airways; gas exchange (oxygen in, carbon dioxide out).
Digestive System: Converts food into fuel, absorbing nutrients.
Urinary System/Renal: Kidneys; maintain blood volume, filter waste.

General Chemistry in Medical Science for Pathology Courses

General Chemistry in Medical Science provides foundational chemical principles (atoms, bonding, reactions, equilibrium, solutions, acids/bases) and links them to biological systems, drug action (pharmacology), and human body processes, covering general, organic, and biochemistry to explain diseases and treatments, crucial for med school prep and understanding medicine at a molecular level.

Core Concepts Covered

Atomic Structure & Bonding: Understanding elements, isotopes, electron configuration, and how atoms form molecules and interact (like in the body).
States of Matter & Thermodynamics: How energy and matter change in biological systems (e.g., metabolism).
Solutions & Acids/Bases: pH balance, buffers, and concentrations in body fluids (blood, etc.).
Kinetics & Equilibrium: Rates of reactions and reversible processes in cells.
Electrochemistry: Electron transfer, vital for respiration and nerve signals.
Organic Chemistry Basics: Carbon compounds, the building blocks of life (carbohydrates, lipids, proteins).
Biochemistry: Applying chemistry to living organisms, essential for understanding diseases and drugs.

Why It’s Important for Medical Science

Disease Understanding: Diseases often involve chemical imbalances or dysfunctional molecular interactions.
Drug Action: Explains how drugs work, their synthesis, and their interaction with the body (Medicinal Chemistry).
Body Processes: Explains fundamental functions like respiration, nerve impulses, and metabolism.
Pre-Med/Med School Prep: Serves as a prerequisite for med school and the MCAT, bridging biology and clinical practice.

Pharmacology for Pathology Courses

Pharmacology is the scientific study of drugs (medicines, chemicals, natural substances) and how they interact with living organisms, covering their origins, effects, uses, and toxicity. It explores both pharmacokinetics (how the body processes drugs: Absorption, Distribution, Metabolism, Excretion – ADME) and pharmacodynamics (how drugs affect the body at molecular/cellular levels). This interdisciplinary field bridges basic sciences like biology, chemistry, and physiology to develop new therapies and ensure safe medication use, distinct from the practice of pharmacy (drug dispensing).

Core Areas of Study

Pharmacokinetics (PK): What the body does to the drug (ADME).
Pharmacodynamics (PD): What the drug does to the body (mechanism, effects, side effects).
Drug Discovery & Development: Identifying targets, designing new molecules, testing safety and efficacy.
Toxicology: Studying the harmful effects of drugs.
Therapeutic Use: Applying drugs to treat diseases.

Key Concepts

Drugs: Any substance (natural, synthetic, chemical, biologic) that affects a biological system.
Receptors: Molecules (often proteins) that drugs bind to initiate effects.
Pharmacogenetics: How genes influence individual drug responses.

Steroid Drugs, Antibiotic Drugs, Anticholesterol Drugs

Steroid Drugs:

Steroid drugs are medications that mimic naturally occurring hormones and primarily fall into two categories: corticosteroids (used medically to reduce inflammation) and anabolic steroids (used to promote muscle growth, often illicitly).

Corticosteroids

Corticosteroids are synthetic versions of hormones produced by the adrenal glands, such as cortisol. They are powerful anti-inflammatory and immunosuppressant medications used to treat a wide variety of conditions.

Common Uses:

Inflammatory conditions: Asthma, allergies, rheumatoid arthritis, lupus, inflammatory bowel disease (Crohn’s disease and ulcerative colitis), and multiple sclerosis.
Skin conditions: Eczema, psoriasis, and other rashes.
Pain management: As an adjuvant for bone, visceral, and neuropathic pain.

Forms of Administration:

Oral: Tablets or liquids (e.g., prednisone, dexamethasone) for systemic conditions.
Inhalers: For respiratory conditions like asthma and COPD.
Topical: Creams or ointments (e.g., hydrocortisone, mometasone) for skin disorders.
Injections: Directly into joints, muscles, or the bloodstream for localized or severe inflammation.

Common Examples of Corticosteroid Drugs:

Prednisone
Dexamethasone
Hydrocortisone
Methylprednisolone
Betamethasone

Antibiotic Drugs:

Antibiotics are powerful medicines used to treat or prevent infections caused by bacteria. They work by killing bacteria or stopping them from growing and multiplying, but they are not effective against viral infections like colds, the flu, or most sore throats.

Types and Examples of Antibiotics

Antibiotics are generally classified into different groups based on their chemical structure and how they work (their mechanism of action).

Group	Mechanism of Action	Common Examples	Common Uses
Penicillins	Inhibit cell wall synthesis	Amoxicillin, Penicillin V, Flucloxacillin	Skin, chest, and urinary tract infections, strep throat
Cephalosporins	Inhibit cell wall synthesis	Cephalexin, Cefdinir, Ceftriaxone	More serious infections like meningitis, some skin infections
Macrolides	Inhibit protein synthesis	Azithromycin, Erythromycin, Clarithromycin	Lung/chest infections (often as a penicillin substitute), pneumonia
Tetracyclines	Inhibit protein synthesis	Doxycycline, Minocycline, Tetracycline	Acne, rosacea, Lyme disease, some specific bacterial infections
Fluoroquinolones	Inhibit DNA synthesis	Ciprofloxacin, Levofloxacin, Moxifloxacin	Urinary tract infections, respiratory tract infections
Aminoglycosides	Inhibit protein synthesis	Gentamicin, Amikacin, Tobramycin	Serious, hospital-only infections (e.g., septicemia)
Sulfonamides	Inhibit folic acid synthesis	Trimethoprim-sulfamethoxazole (Bactrim)	UTIs, some types of pneumonia

Important Considerations

Prescription Only: Antibiotics are powerful medications that can only be obtained with a prescription from a healthcare provider.
Follow Instructions: It is crucial to follow the doctor’s instructions carefully and complete the entire course of medication, even if you start feeling better. Stopping treatment early can allow some bacteria to survive, which can lead to a return of the infection or, more seriously, antibiotic resistance.
Antibiotic Resistance: Overuse or misuse of antibiotics is a major public health concern that leads to bacteria adapting and becoming “superbugs” that existing medicines can no longer treat effectively.
Side Effects: Common side effects can include nausea, diarrhea, and rash. More serious side effects can occur, including severe allergic reactions or C. difficile infections.
Alcohol Interaction: While many antibiotics are safe to take with moderate alcohol consumption, certain types, such as metronidazole, can cause severe reactions. Always consult your doctor or pharmacist about potential interactions.

Anticholesterol Drugs:

Anti-cholesterol drugs, primarily Statins (like atorvastatin, rosuvastatin, simvastatin), are first-line treatments that block liver cholesterol production to prevent heart attacks and strokes, but alternatives exist like Ezetimibe, Bempedoic Acid, Fibrates, Bile Acid Sequestrants, and Niacin, often combined with diet and exercise for comprehensive management.

Main Types of Anti-Cholesterol Drugs

Statins: Most common, reduce the liver’s cholesterol production (e.g., Atorvastatin, Rosuvastatin, Simvastatin).
Ezetimibe (Zetia): Blocks cholesterol absorption in the intestine; can be used with or without statins.
Bempedoic Acid (Nexletol): An ATP citrate lyase (ACL) inhibitor, reduces liver cholesterol synthesis, good for those who can’t tolerate statins.
Fibrates (e.g., Fenofibrate): Primarily lower triglycerides but also affect cholesterol.
Bile Acid Sequestrants (e.g., Cholestyramine): Bind to bile acids, forcing the body to use cholesterol to make more.
Niacin (Nicotinic Acid): A B-vitamin in high doses that lowers fats, but has significant flushing side effects.

How They Work

Statins: block an enzyme in the liver, reducing the amount of cholesterol made.
Ezetimibe: prevents cholesterol from being absorbed from the gut.
Fibrates and Niacin affect how the body processes fats (triglycerides and cholesterol).

Biochemistry for Pathology Courses

Biochemistry is the study of chemical processes and substances within living organisms, focusing on life at the molecular level, exploring biomolecules (like proteins, DNA, lipids, carbs) and the reactions that sustain life, energy use, and disease.

Dynamic Field: Constantly evolving with new technologies like genomics and automation.

CBC Test

A CBC (Complete Blood Count) is a common blood test that checks your overall health by measuring and analyzing the different cells in your blood: red blood cells (oxygen transport), white blood cells (infection fighting), and platelets (clotting). It helps diagnose conditions like anemia, infections, inflammation, or leukemia, and monitors existing treatments, usually involving a simple blood draw from a vein.

What it measures

White Blood Cells (WBC): Fights infection (total count and differential types).
Red Blood Cells (RBC): Carries oxygen (count, Hemoglobin, Hematocrit, size/indices like MCV).
Platelets: Help blood clot.
Hemoglobin (Hb): Oxygen-carrying protein in RBCs.
Hematocrit (Hct): Proportion of blood volume made of RBCs.

Why is it done

Part of routine checkups.
Investigate symptoms like fatigue, fever, bruising, or weakness.
Monitor chronic diseases (e.g., kidney disease, cancer).
Check response to treatments or medications.

How it’s done

A nurse draws a small blood sample from a vein, usually in your arm.
The sample is analyzed by an automated machine.
Results compare your levels to normal ranges, flagging any highs or lows.

Total Count Blood Test (TC)

A “total count blood test” usually refers to a Complete Blood Count (CBC), a common panel that measures the types and numbers of cells in your blood (Red Blood Cells, White Blood Cells, Platelets), plus key metrics like Hemoglobin and Hematocrit, to check overall health, diagnose conditions like anemia or infection, and monitor treatments, by analyzing if cell levels are too high (infection/inflammation) or low (bleeding/bone marrow issues).

What it measures:

Red Blood Cells (RBCs): Carry oxygen. (Count, Hemoglobin, Hematocrit).
White Blood Cells (WBCs): Fight infection (Count, plus a “Differential” to see types: Neutrophils, Lymphocytes, etc.).
Plate00
.
lets (PLTs): Help blood clot (Count, Mean Platelet Volume).

Why it’s done:

Detects infections, anemia, inflammation, and bleeding disorders.
Checks general health and monitors chronic diseases.
Evaluates symptoms like fatigue, weakness, or bruising.

How it works:

A healthcare professional takes a blood sample from a vein in your arm.
The lab counts the cells and measures other components.

What results mean (briefly):

High WBC: Might mean infection or inflammation.
Low Hemoglobin/RBC: Often anemia.
High/Low Platelets: Can relate to clotting issues or bone marrow problems.

Clinical Procedure for Total Count Blood Test (TC)

The Total Count (TC) blood test, which is part of a Complete Blood Count (CBC), is a simple procedure involving a standard blood draw (venipuncture) performed by a healthcare professional. The sample is then analyzed in a laboratory to measure the total number of white blood cells (leukocytes) in your blood.

Preparation for the TC Blood Test

Generally, no specific preparation is required for a TC blood test.

Fasting is usually not necessary unless your doctor has ordered additional tests on the same blood sample that require it (such as a cholesterol test).
Medication: Inform your healthcare provider about all medications, supplements, or recent medical treatments (like chemotherapy or radiation) you are taking, as some can affect the results. Your doctor may advise you to stop certain medications temporarily.
Clothing: Wear a short-sleeved shirt or a shirt with sleeves that can be easily rolled up to provide easy access to your arm.

Procedure for the TC Blood Test

The procedure is quick and is typically performed by a phlebotomist (a healthcare professional trained in drawing blood) in a clinic, hospital, or lab setting.

Site Selection and Cleaning: The technician will select a vein, usually from the inside of your elbow or the back of your hand. They will clean the area with an antiseptic wipe to prevent infection.
Tourniquet Application: An elastic band (tourniquet) is placed around your upper arm to make the vein swell with blood and become more visible.
Blood Collection: A sterile needle connected to a collection tube is inserted into the vein. You may feel a brief sting or pinch when the needle is inserted.
Sample Collection: A small amount of blood is collected into one or more vials.
Bandaging: After the required amount of blood is drawn, the elastic band and needle are removed, and a bandage or cotton pad is applied to the puncture site to stop any bleeding.
Lab Analysis: The collected sample is labeled and sent to a laboratory for analysis, often using automated analyzers to count the white blood cells.

Post-Procedure and Results

After the test, you can usually return to your normal daily activities right away. There is minimal risk, with slight pain or bruising at the needle insertion site being the most common side effects.

Results are typically available within hours to a day and should be discussed with your healthcare provider for proper interpretation and diagnosis. The normal range for a total white blood cell count in adults is generally between 4,000 and 11,000 cells per microliter of blood, but range can vary slightly by laboratory.

Differential Count Blood Test (DC)

A Differential Count (DC) blood test, often part of a Complete Blood Count (CBC), provides a detailed breakdown of the different types of white blood cells (WBCs)—neutrophils, lymphocytes, monocytes, eosinophils, and basophils—to assess immune function, diagnose infections, inflammation, allergies, and blood disorders like leukemia, by revealing percentages and absolute numbers of each cell type, which helps identify issues beyond a simple WBC count.

What it measures

The test quantifies the five main types of WBCs:

Neutrophils: Fight bacterial infections.
Lymphocytes (B & T cells): Target viruses, cancer cells, and produce antibodies.
Monocytes: Remove pathogens and dead cells.
Eosinophils: Combat parasites and manage allergic reactions.
Basophils: Release enzymes during allergic responses.

Why is it done

Diagnose Infections & Inflammation: Identify bacterial (high neutrophils) or viral (high lymphocytes) issues.
Detect Allergic Reactions: High eosinophils suggest allergies or parasites.
Monitor Immune Disorders: Assess conditions like autoimmune diseases or HIV.
Screen for Blood Cancers: Detect abnormal WBCs or blasts.
Evaluate Symptoms: Investigate fatigue, unexplained bruising, or frequent infections.

How it works

A blood sample is taken, often as part of a CBC.
A lab technician examines a blood smear under a microscope or uses automated analyzers.
They count and classify 100-200 WBCs, noting percentages.
These percentages are multiplied by the total WBC count (from the CBC) to get absolute counts, which are more informative than percentages alone.

What results mean

High Counts: Can indicate infection, inflammation, stress, or certain diseases.
Low Counts: May signal a weakened immune system, bone marrow issues, or damage from treatments like chemotherapy.
Abnormal Ratios: Reveal specific problems, like an excess of immature cells pointing to leukemia.

Clinical Procedure for Differential Count Blood Test (DC)

The clinical procedure for a Differential Count (DC) blood test involves two main stages: blood sample collection and laboratory analysis. Analysis can be performed using either automated analyzers or a manual microscopic method.

I. Sample Collection (Phlebotomy)

No special preparation, such as fasting, is usually required for a DC test.

A healthcare professional, such as a phlebotomist, will typically draw a blood sample from a vein in the inside of your elbow or the back of your hand. For infants, a heel prick may be used.
The skin is cleaned with an antiseptic wipe.
An elastic band (tourniquet) is placed around the upper arm to make the vein swell with blood and easier to access.
A sterile needle is inserted into the vein, and a small amount of blood is collected into a test tube or vial, typically one with a purple or lavender top containing the anticoagulant EDTA to prevent clotting.
The tourniquet is removed, the needle is withdrawn, and a bandage is applied to the puncture site to stop any bleeding.

II. Laboratory Analysis

Once in the lab, the sample is processed to identify and count the five major types of white blood cells (WBCs): neutrophils, lymphocytes, monocytes, eosinophils, and basophils.

A. Automated Differential Count

Most differentials are performed using automated hematology analyzers, which are faster and more accurate than manual methods for general screening.

The machine uses methods like fluorescence flow cytometry, electrical impedance, and light scatter to analyze thousands of cells and categorize them by size, shape, and internal properties.
The results are typically reported as both percentages and absolute counts.
If the automated system detects abnormal results, the sample is flagged for a manual review by a trained laboratory specialist.

B. Manual Differential Count (Microscopic Review)

A manual count is performed when an automated test shows unusual results or when a physician specifically requests it.

Smear Preparation: A drop of the blood sample is thinly spread across a glass slide to create a blood film and allowed to air dry.
Staining: A special dye, usually a Romanowsky stain like Wright’s or Giemsa stain, is applied to the smear. The stain helps differentiate the various cell types based on their morphology, including nuclear features and cytoplasmic granules.
Microscopic Examination: A trained laboratory specialist examines the stained slide under a microscope, using oil immersion (1000x magnification) if necessary, to identify cells based on their appearance.
Counting and Classification: The specialist systematically scans a specific area of the smear, counting and classifying at least 100 white blood cells.
Reporting: The counts are recorded (often using a manual counter) and converted into percentages and absolute values. The report may also note any abnormal or immature cells.
