Anterior (ventral)
Toward the front
Posterior (dorsal)
Toward the back
Superior (cranial)
Toward the head
Inferior (caudal)
Toward the tail
Proximal
Closer to the point of origin (generally the trunk)
Distal
Farther away from the point of origin (generally the trunk)
Medial
Closer to the midline of the body or body part; on the inner side of
Lateral
Farther away from the midline of the body or body part; on the outer side
Superficial
Closer to the surface
Deep
Farther below the surface
Sagittal plane
Vertically divides the body for structure into right and left sides
Midsagittal plane
Divides the body or structure into right and left halves
Transverse/horizontal plane
Any plane that divides the body into superior and inferior portions
Coronal /frontal plane
Any plane that divides the body at right angles to the midsagittal plane; the coronal planes the body into anterior and posterior portions
Ventral cavity
The hollow portion of the human torso extending from the neck to the pelvis
Thoracic cavity
Contains the heart (pericardial cavity), the lungs (pleural cavities), esophagus, trachea, thymus, and certain large blood and lymph vessels
Abdominal
The space below the diaphragm, commonly referred to as the belly; contains the stomach, intestines, and other organs of digestion
Pelvic cavity
The space formed by bones of the pelvis area; contains organs of reproduction and elimination
Dorsal cavity
Contains the structure of the nervous system and is subdivided into the cranial cavity and the spiral cavity
Cranial cavity
The space in the skull containing the brain
Spinal cavity
The space within the bony spinal cord and spinal fluid
Abdominoplevic cavity
Combination of the abdominal and pelvic cavities; is divided into nine regions
Right hypochondriac
Upper right region at the level of the ninth rib cartilage
Left hypochondriac
Upper left region at the level of the ninth rib cartilage
