Study Notes
Homeostasis and Regulation
- Effectors respond to signals from the control center to maintain homeostatic balance.
- Homeostasis refers to a stable internal environment maintained by various physiological processes.
- The two major regulatory systems in the human body are the nervous and endocrine systems.
Anatomy and Physiology
- Anatomy studies structure, while physiology examines function.
- Systemic anatomy focuses on organ systems; surface anatomy studies external features.
- Cytology analyzes individual cells, whereas histology investigates tissue structures.
Body Cavities and Sections
- The thoracic cavity is superior to the abdominopelvic cavity and subdivided into pleural and pericardial cavities.
- The heart and lungs are located within the thoracic cavity.
- The ventral body cavity is divided by the diaphragm into thoracic and abdominopelvic cavities.
- Sagittal sections divide the body into right and left portions; parasagittal sections run parallel to the midsagittal plane.
Anatomical Terms and Relationships
- Supine refers to lying face up; anatomical position includes standing erect with feet forward, arms at sides, and palms facing forward.
- Proximal movement is towards the trunk of the body; distal refers to movement away from it.
- Medial surfaces are close to the body's midline, whereas lateral surfaces are farther from it.
Feedback Mechanisms
- Negative feedback counteracts change and promotes stability; an example includes temperature regulation.
- Positive feedback amplifies a process, as seen in blood clotting mechanisms.
Body Regions and Systems
- The right upper quadrant of the abdomen contains the liver.
- The femoral region refers to the thigh; the anatomical term for the calf is sura.
- The cardiovascular system is responsible for distributing oxygen and carbon dioxide throughout the body.
Levels of Organization
- Biological organization progresses from chemicals to cells, tissues, organs, organ systems, and finally to the organism.
- Each level of organization is interdependent; damage at one level can affect the entire system.
Common Anatomical Terms
- Brachium refers to the arm; the term for the forearm is antebrachium.
- The stomach is located in the abdominal cavity, while the pelvic cavity houses female reproductive organs.
Directional Terms
- Anterior and ventral are synonymous; posterior aligns with dorsal.
- Superior indicates above, while inferior denotes below; cephalic refers to the head and caudal to the tail or feet.
Key Organ Systems
- The skeletal system includes bones, ligaments, and cartilage.
- Heat production is primarily a function of the muscular system.
- Cells group to form tissues in complex organisms, underscoring the relationship between structure and function.
