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
