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.
