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.
