Study Notes
Anatomy and Physiology Overview
- Anatomy is the study of structures and their relationships.
- Physiology focuses on body functions and how parts work.
- Structure often dictates function in biological systems.
Levels of Anatomy Study
- Gross Anatomy: Involves large structures visible to the naked eye.
- Microscopic Anatomy/Histology: Examines structures only visible with a microscope.
- Neuroanatomy: Studies features and development of the nervous system.
- Embryology: Explores human development from fertilization to birth.
Divisions of Anatomy and Physiology
- Cell Physiology
- Neurophysiology
- Pathophysiology
- Cardiovascular Physiology
- Respiratory Physiology
- Renal Physiology
- Endocrinology
- Exercise Physiology
Organ Systems and Their Functions
- Integumentary System: Protects body and synthesizes vitamin D; houses nerve receptors.
- Skeletal System: Supports and protects organs; site of blood cell formation; stores minerals.
- Muscular System: Facilitates movement and maintains posture; generates heat.
- Nervous System: Fast-acting control system; activates muscles and glands based on internal/external changes.
- Endocrine System: Regulates growth, metabolism, and reproduction through hormone secretion.
- Cardiovascular System: Transports oxygen, nutrients, and wastes via the blood.
- Lymphatic System: Returns body fluids to circulation, disposes of debris, and supports immunity.
- Respiratory System: Supplies blood with oxygen and removes carbon dioxide.
- Digestive System: Breaks down food for nutrient absorption and eliminates waste.
- Urinary System: Removes nitrogenous wastes and regulates water and electrolytes.
- Reproductive System: Responsible for producing offspring.
Anatomical Terminology
- Terminology is crucial for avoiding misunderstandings and includes terms for position, direction, and structure.
Anatomical Position
- Standing erect with head, eyes, and toes directed forward.
- Heels and toes are together and flat; arms are at sides with palms facing forward.
Anatomical Planes
- Median Plane: Divides the body into equal right and left halves.
- Sagittal Plane: Divides the body into unequal right and left sides.
- Coronal (Frontal) Plane: Divides body into front and back portions.
Orientation and Directional Terms
- Superficial: Closer to the body surface.
- Deep: Farther from the surface.
- Ipsilateral: On the same side.
- Contralateral: On opposite sides.
Body Movements
- Flexion: Decreases the angle between body parts.
- Extension: Increases the angle; joints are straightened.
- Rotation: Movement around an axis.
- Abduction: Movement away from the midline.
- Adduction: Movement toward the midline.
- Circumduction: Circular movement of a limb.
Special Body Movements
- Protraction: Forward movement (e.g., jaw forward).
- Retraction: Backward movement.
- Elevation: Raising a body part.
- Depression: Lowering a body part.
- Supination: Forearm position with palm facing up.
- Pronation: Forearm position with palm facing down.
- Inversion: Foot sole turns inward.
- Eversion: Foot sole turns outward.
Body Cavities
- Dorsal Cavity: Includes cranial and vertebral cavities.
- Ventral Cavity: Divided into thoracic, abdominal, and pelvic cavities.
Abdominopelvic Regions and Quadrants
- Important for locating major organs and diagnosing conditions.
Life Processes
- Metabolism: All chemical processes in the body.
- Responsiveness: Ability to detect and respond to environmental changes.
- Movement: Motion of the body, organs, cells, and organelles.
- Growth: Increase in size from cell size, number, or surrounding material.
- Differentiation: Process whereby unspecialized cells develop into specialized cells.
- Reproduction: Formation of new cells or individuals.
Homeostasis
- Maintenance of internal stability despite external changes.
