Study Notes
Body Parts and Regions
- The lower limb is divided into thigh, leg, ankle, and foot.
- Thigh extends from hip to knee; leg extends from knee to ankle.
- Familiarity with body parts aids communication among healthcare providers.
Abdominal Regions and Quadrants
- Abdominopelvic cavity occupies a large area, making problem location challenging.
- Cavity is subdivided into regions and quadrants for better assessment.
- Some organs extend across multiple quadrants.
Planes of the Body
- Body planes section the body and organs for anatomical analysis.
- Longitudinal section: cut along the long axis of an organ.
- Transverse section: cut at a right angle to the long axis.
- Oblique section: cut across the long axis at any angle other than right.
Body Cavities
- Two primary body cavities: dorsal and ventral.
- Each cavity is further subdivided to house and protect internal organs.
Serous Membranes
- Serous membranes line trunk cavities and cover organs within them.
- Filled with fluid to reduce friction between moving organs.
- Notable in childbirth where oxytocin induces uterine contractions through a positive feedback system.
Body Positions
- Anatomical position: upright, head level, eyes forward, feet flat and forward, arms at sides with palms facing forward.
- Prone position: lying face down.
- Supine position: lying face up.
Directional Terms
- Directional terms indicate positions of body parts in relation to each other and often come in opposite pairs.
General Body Structures
- Body's central region consists of head, neck, and trunk.
- Trunk is divided into thorax (chest), abdomen, and pelvis.
- Upper limb divided into arm (shoulder to elbow), forearm (elbow to wrist), wrist, and hand.
