When analyzing movements, we can observe each joint action through or
parallel to, a flat plane of motion. A helpful way to think of a plane is as a
large sharp razor, that slices the body or limb moving through it, in two.
The body's parts can also be separated into axial and appendicular portions.
Different terms are used for the smaller areas of the body and they are the following:
Cephalic-head Cranial-skull Frontal-forehead Occipital-back of head Oral-mouth Nasal-nose Ophthalmic-orbital, eyes
Pectoral-chest Mammary-breast Axillary-armpit Vertebral-backbone Costal-ribs
Celiac-abdomen Pelvic-lower portion of abdomen Gluteal-buttock Inguinal-groin Groin-depressed region of abdomen near thigh Lumbar-lower back Sacral-where vertebrae terminate Perineal-region between anus and external sex organs
Limbs (arms and legs)
Brachial-upper arm Forearm-lower arm Carpal-wrist Cubital-elbow Palmar-palm Lower limb-leg Femoral-thigh Popliteal-back of knee Lower leg-distal to the knee Pedal-foot
The mediastinum, a mass of tissues and organs, divides the pleural cavities.
The diaphragm is a muscle that divides the thoracic and the abdominopelvic cavity.
The abdominal cavity can be further split into the upper abdominal and lower pelvic cavities. This is where most of the digestive organs such as the stomach and liver reside.
Finally, the abdominopelvic cavity can also be split into the umbilical, lumbar, epigastric, hypochondriac, hypogastric, and illiac cavities.
