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.
