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.
