Structure of organ systems smallest to largest

Anterior
AKA ventral. Toward the front of the body
Posterior
AKA dorsal. Toward the back of the body
Medial

Lateral
Further from the midline of the body
Proximal
Closer to the trunk of the body

Superficial
Closer to the surface of the body
Deep

Sagittal plane, midsagittal
Divides the body into left and right sides. Midsagittal refers to an equal division of left and right sides
Transverse plane
Divides the body into upper and lower sections, not necessarily equally
Frontal plane
AKA coronal plane, divides the body into anterior and posterio sections
Five cavities of the body
Cranial, spinal, thoracic, abdominal, pelvic
Cranial cavity
Within the body cranium, houses the meninges (brain)
Spinal cavity
A continuation of the cranial cavity as it travels down the midline of the back
Thoracic cavity
Within the chest, houses the lungs, heart, and major vessels
Abdominal cavity
Within the abdomen, houses several major organs
Pelvic cavity
Inferior to the abdominal cavity, houses the bladder
Four body quadrants
Divide the abdomen section below the rib cage.
Useful for documenting chief complaint.
