abdominopelvic cavity

on of the 2 parts that the diaphragm divides the ventral body cavity into: the inferior _______________________ cavity.

anatomical position

The subject or patient is erect, facing the viewer, with feet pointed ahead, arms at the sides, and the palms of the hands turned forward.

appendicular region

One of the fundamental regions of the body, consisting of the limbs or extremities.

axial region

One of the fundamental regions of the body, consisting of the head, neck, and trunk.

body cavities

hollow spaces within the body that contain internal organs: dorsal (includes cranial cavity and spinal canal), ventral (includes thoracic cavity and abdominopelvic cavity), and scrotal (present in males only)

directional terms

The terms used to describe the relationships of individual structures and regions.

frontal section

Passes parallel to the midline and at right angles to the plane of the sagittal section and would divide the body into dorsal and ventral portions.

horizontal section

A cut at right angles to the midline and dividing the body into superior and inferior portions.

midline

The median line or median plane of the body or some part of the body.

midsagittal section

If the body were sliced into equal right and left halves, this cut would pass through the sagittal plane along the midline of the body.

parasagittal planes

Planes that cut the body to the right or left of the midline, generating unequal portions.

scrotal cavity

A hollow internal space present only in males.

thoracic cavity

The diaphragm, a sheet of muscle, divides the ventral body cavity one of these is the superior part enclosed by the ribcage called the ___________________

transverse section

The horizontal plane that is the result of a horizontal cut that divides the body into superior and inferior parts.

ventral body cavity

Contains the soft internal organs.

vertebral column

The spine.

vertebral canal

The spinal canal within the vertebral column.

cephalad

toward the head or superior

caudad

toward the tail or inferior, away from the head

ventral

anterior or in front

dorsal

posterior or in the back

medial

nearer to the midline

lateral

ipsilateral

on the same side as

contralateral

on the opposite side from

proximal
