Study Notes

Anatomy Terminology

Root Words: Key prefixes and suffixes used in anatomy include:
- caput-, cephal- = Head
- cervic-, cervix = Neck
- dors- = The Back
- ventr- = Abdomen
- cutic-, derm- = Skin
- cyt- = Cell
- lip-, lipo- = Fat/Lipid
- myo- = Muscle
- osteo- = Bone

Anatomical Structure and Function

Anatomy: Focuses on the study of body structures through observation.
Physiology: Examines how structures function; changes in structure can alter function.

Levels of Structural Organization

Chemical Level: Atoms combine to form molecules.
Levels: Organ systems are organized into a hierarchy: Cells, Tissues, Organs, Organ Systems, Organism.

Organ Systems

Eleven organ systems are integral to human body function:
- Integumentary
- Skeletal
- Muscular
- Nervous
- Endocrine
- Cardiovascular
- Lymphatic
- Respiratory
- Digestive
- Urinary
- Reproductive

Key Functions to Maintain Life

Organisms must:
- Maintain boundaries
- Move and respond to stimuli
- Digest nutrients and excrete wastes
- Carry out metabolism
- Reproduce and grow
Survival Needs: Food, Oxygen, Water, Appropriate temperature, Normal atmospheric pressure. Extremes in these factors can be harmful.

Anatomical Position and Directional Terms

Anatomical Position: Standing erect with palms facing forward, serving as a reference.
Directional terms describe locations relative to body parts.

Body Planes and Sections

Sagittal Section: Divides the body into right and left parts.
Frontal Section: Splits the body into anterior (front) and posterior (back) parts.
Transverse Section: Cuts the body horizontally into superior (upper) and inferior (lower) parts.

Body Cavities

Dorsal Cavity: Protected by bone, consisting of:
- Cranial Cavity: Houses the brain.
- Spinal Cavity: Encases the spinal cord.
Ventral Cavity: Less protected, includes:
- Thoracic Cavity: Contains heart and lungs, protected by rib cage.
- Abdominopelvic Cavity: Houses digestive, urinary, reproductive organs; vulnerable protection.

Major Body Landmarks

Anterior Landmarks: Include regions such as abdominal, acromial, antecubital, cervical, and pelvic.
Posterior Landmarks: Features regions like calcaneal, femoral, gluteal, and vertebral.

Notes Summary

Understanding anatomical terms and structures is crucial for the study of human physiology and medical practices.
Recognizes the importance of diverse organ systems and their functions in sustaining life processes.
