CHAPTER 4: PART 1 (POSITION, PLANES, CAVITIES)

CORONAL PLANE

anatomial division: Anterior (ventral) and posterior (dorsal) aspects

MIDSAGITTAL PLANE

anatomical division: Right and left halves

TRANSVERSE PLANE

Superior (upper) and inferior (lower) aspects

ANATOMICAL POSITION

A standard reference posture in which the body stands upright, facing forward, with arms at the sides and palms facing forward.

PLANES OF THE BODY

Imaginary flat surfaces—sagittal, frontal (coronal), and transverse—that divide the body into sections for anatomical study.

BODY CAVITIES

Hollow spaces within the body that house and protect organs, including the cranial, spinal, thoracic, abdominal, and pelvic cavities.

ABDOMINOPELVIC DIVISIONS

The division of the abdominopelvic cavity into quadrants (RUQ, LUQ, RLQ, LLQ) or nine regions for medical and anatomical reference.

DIRECTIONAL TERMS
