Ch 1 Terms 2

Transverse Section

Transverse Section

a cut in the transverse plane; cross section

Frontal Plane

dividing the body from anterior (front) and posterior (back); coronal plane

Viscera

lining that partially covers organs

Pericardial Cavity

a small chamber that surrounds the heart

Transverse Plane

dividing the body into superior (top half) and inferior (bottom half) portions

Cranial/Cephalic

head (top)

Diaphragm

flat muscular sheet that seperates the ventral body cavity into superior thoracic cavity and inferior abdominapelvic cavity

Mediastinum

divides thoracic cavity into left and right pleural cavities

Anatomical Position

hands at the side, palms facing forward, feet together

Lateral

away from the body’s longitudinal axis

Abdominapelvic Cavity

enclosed by the abdominal wall, and the bones and muscles of the pelvis

Supine

person laying down faced up in anatomical position

Thoracic Cavity

bounded by the chest wall

Medial

Towards the body’s longitudinal axis

Sagittal Plane

dividing the body from left and right

Ventral Body Cavity

appears early in embryologial development containing the respiratory, cardiovascular, digestive, urinary, and reproductive systems

Prone

person laying down faced up in anatomical position

Pleural Cavities

contains a lung in the thoracic cavity; seperated by mediastinum

Abdominapelvic Quadrants

formed by a pair of imaginary perpendicular lines that intersect at the naval

Deep

farther from the body surface

Superior

above; at a higher level

Abdominapelvic Regions

provides more precise regional descriptions

Anterior

the front; before

Proximal

toward an attached base

Ventral

the belly side (equivalental to anterior)

Distal

away from an attached base

Caudal

tail (coccyx)

Inferior

below; at a lower level

Sectional Planes

slices through 3d objects

Posterior/Dorsal

the back; behind

Superficial

at, near, or relatively close to the body surface
