Study Notes
Anatomy and Physiology Overview
- Anatomy studies the structural organization of the body; it involves dissection to examine bodily structures.
- Physiology investigates the functions and processes of living organisms, focusing on how body systems operate.
Types of Anatomy
- Developmental Anatomy: Explores structural changes from conception to adulthood.
- Gross Anatomy: Investigates structures observable without a microscope, approached either systematically (by system) or regionally (by area).
- Cell Physiology: Examines cellular processes, such as energy production.
- Systemic Physiology: Focuses on the functions of organ systems, e.g., cardiovascular and neurophysiology.
Levels of Organization
- Chemical Level: Involves atom interactions forming molecules; e.g., hydrogen and carbon.
- Cell Level: Cells are basic structural and functional units, containing organelles that perform specific tasks.
- Tissue Level: Tissues are groups of similar cells with surrounding materials that determine their functional roles.
- Organ Level: Organs are formed from two or more tissue types working together to perform complex functions.
- Organ System Level: Groups of organs collaborate for common purposes (e.g., respiratory system).
- Organism Level: An individual living entity made up of one or more cells.
Characteristics of Life
- Organization: Specific interrelationships among body parts to function cohesively.
- Metabolism: Energy utilization for vital functions such as growth and reproduction.
- Responsiveness: Adjusting to environmental changes, both internal and external.
Homeostasis
- The maintenance of stable internal conditions; emphasizes negative feedback mechanisms to return to set points.
- Positive feedback mechanisms amplify responses, seen in blood clot formation and childbirth, but can lead to detrimental effects if mishandled.
Body Position and Terminology
- Anatomical Position: Body standing upright, facing forward, arms at sides with palms facing forward.
-
Directional Terms:
- Superior (toward the head) and inferior (away from the head)
- Anterior (front) and posterior (back)
- Cephalic and caudal can also be used interchangeably.
Body Plans and Sections
-
Planes: Imaginary flat surfaces that divide the body:
- Sagittal Plane: Divides into right and left sections.
- Medial Plane: A sagittal cut along the midline creating equal halves.
- Transverse Plane: Divides the body into superior (upper) and inferior (lower) parts.
- Frontal Plane: Divides body into anterior (front) and posterior (back) sections.
Body Cavities
- Abdominal Cavity: Contains most digestive organs, part of the peritoneal cavity.
- Pelvic Cavity: Houses urinary bladder, large intestine, reproductive organs.
-
Serous Membranes: Line body cavities, comprising:
- Parietal Serous Membrane: Lines cavity walls.
- Visceral Serous Membrane: Covers internal organs, separated by serous fluid.
Thoracic Cavity Membranes
- Pericardial Cavity: Surrounds the heart; parietal pericardium lines the cavity and visceral pericardium covers the heart.
- Pleural Cavity: Surrounds each lung; contains parietal pleura (lining) and visceral pleura (covering lungs).
- Peritoneal Cavity: Contains various internal organs with layers of peritoneal membranes.
