Study Notes
Introduction
- Anatomy is the study of structure, physiology is the study of function.
- Macroscopic anatomy examines large structures visible without magnification (e.g., organs, limbs).
- Microscopic anatomy examines tiny structures needing magnification (e.g., cells, tissues).
- Structure and function are interconnected in the human body.
- Levels of organization (smallest to largest): Chemical, Cells, Tissues, Organs, Organ Systems, Organism.
Organ Systems
- Integumentary: Protects, regulates temperature, sensory reception (skin, glands, hair, nails).
- Skeletal: Supports, protects, assists movement, blood cell production (bones, joints, cartilage).
- Muscular: Movement, heat generation (muscles).
- Nervous: Controls and coordinates bodily functions (brain, spinal cord, nerves).
- Endocrine: Regulates growth, development, and various bodily functions using hormones (glands).
- Cardiovascular: Delivers nutrients and oxygen, removes waste (heart, blood vessels, blood).
- Lymphatic: Filters fluid, manages immune responses (lymph nodes, vessels, tonsils, etc.).
- Respiratory: Gas exchange (nose, pharynx, trachea, lungs).
- Urinary: Blood filtration, fluid/electrolyte balance (kidneys, ureters, bladder, urethra).
- Digestive: Digestion of food, nutrient absorption, waste removal (mouth, esophagus, stomach, liver, intestines).
- Reproductive: Hormone production, perpetuation (vagina, uterus, ovaries, or penis, testes).
Homeostasis
- Maintaining stable internal conditions.
- Control system elements: Regulated variable (what needs to be monitored), Stimulus (cause of change), Receptor (detects change), Integrator (determines necessary response), Effector (makes adjustments).
Feedback Mechanisms
- Negative feedback: Maintains stability, brings the body back to a normal range (e.g., body temperature regulation, blood pressure).
- Positive feedback: Amplifies deviation from the norm, until a critical point is reached, then returns to normal (e.g., childbirth, blood clotting).
Anatomical Position
- Standing upright, feet shoulder width apart, facing forward, arms at sides, palms forward.
Body Cavities
- Cranial (brain), Spinal (spine), Thoracic (heart), Abdominal (stomach), Pelvic (uterus).
- Ventral and Dorsal (front/back).
Directional Terms
- Superior/inferior, medial/lateral, proximal/distal, anterior/posterior, ventral/dorsal, cranial/caudal, superficial/deep.
Body Planes
- Transverse (top/bottom halves), Coronal (front/back halves), Sagittal (left/right halves).
- Midsagittal (equal left and right portions), Parasagittal (unequal left and right portions).
Abdominopelvic Regions
- Quadrants (RUQ, LUQ, RLQ, LLQ) and regions, major structures in each.
Tissues
- Epithelial: Covers and lines body surfaces; functions varied - protection, absorption, secretion, excretion.
- Connective: Supports and connects body parts; diverse functions like transport, support, and storage.
- Muscle: Movement; skeletal, smooth, or cardiac.
- Nervous: Communication; neurons and glial cells.
Integumentary System Details
- The skin's layers (epidermis, dermis, hypodermis).
- Accessory structures (hair, nails, sweat glands, sebaceous glands).
- Functions include protection, temperature regulation, sensory reception, and vitamin D production.
