Study Notes

Pathological Anatomy and Pathophysiology

Pathological anatomy involves structural changes (both gross and microscopic) associated with diseases.
Pathophysiology examines functional changes linked to disease and aging.

Levels of Structural Organization

Six levels of organization in the human body: chemical, cellular, tissue, organ, system, and organismal.
Chemical Level: Consists of atoms like carbon (C), hydrogen (H), oxygen (O), nitrogen (N), phosphorus (P), calcium (Ca), and sulfur (S), essential for life.
Cellular Level: Cells are the basic unit of life, formed from atoms and molecules.
Tissue Level: Tissues consist of groups of similar cells performing specific functions; includes epithelial, connective, muscular, and nervous tissues.
Organ Level: Organs are composed of two or more types of tissues; examples include the stomach, skin, heart, and lungs.
System Level: Organ systems consist of related organs with specific functions, such as the digestive and urinary systems.
Organismal Level: The whole being functions together like a complete book.

Organs and their Functions

Organs perform specialized functions based on their structural compositions, e.g., the stomach aids in digestion.
[Digestive System Components]: Organs include the stomach, intestines, liver, and pancreas, allowing digestion and absorption of nutrients.
[Urinary System Components]: Includes kidneys, ureters, bladder, and urethra, crucial for expelling waste and regulating fluid balance.

Diagnosis

Diagnosis is the process of distinguishing diseases using symptoms, signs, medical history, and physical examinations.
A standard anatomical position is used for clarity: standing erect, facing forward, with arms at the sides and palms facing forward.

Body Planes and Sections

Anatomical planes (midsagittal, frontal, transverse, and oblique) divide the body for analysis and understanding:
- Midsagittal Plane: Divides body into left and right halves.
- Frontal Plane: Divides body into anterior (front) and posterior (back) sections.
- Transverse Plane: Divides body into superior (upper) and inferior (lower) portions.
- Oblique Plane: Cuts through the body at angles other than right angles, providing unique views.
