That might be an organ, a region in the body, or an anatomical structure. For example, the central nervous system and the peripheral nervous systems. Central (from Latin centralis) describes something close to the centre. [33] For example, the great vessels run centrally through the body; many smaller vessels branch from these.
Superior and inferior, which describe a position above (superior) or below (inferior) another part of the body. For example, the orbits are superior to the oris, and the pelvis is inferior to the abdomen. [1] Proximal and distal, which describe a position that is closer to (proximal) or farther from (distal) the trunk of the body. [1]
Inferior border of the heart; The transpyloric plane. Plane located halfway between the jugular notch and the upper border of the symphysis pubis; Typically located at the lower border of L1; Cuts through the pylorus and the tips of the ninth costal cartilages; The subcostal plane. Transverse plane through the inferior border of costal margin;
The inferior branch of the oculomotor nerve or the inferior division, the larger, divides into three branches. One passes beneath the optic nerve to the medial rectus. Another, to the inferior rectus. The third and longest runs forward between the inferior recti and lateralis to the inferior oblique.
Brodmann area 43, the subcentral area, is a structurally distinct area of the cerebral cortex defined on the basis of cytoarchitecture.Along with Brodmann Area 1, 2, and 3, Brodmann area 43 is a subdivision of the postcentral region of the brain, [1] suggesting a somatosensory ('feeling of the body') function.
A simple example of this type of correspondence is the primary motor cortex, a strip of tissue running along the anterior edge of the central sulcus. Motor areas innervating each part of the body arise from a distinct zone, with neighboring body parts represented by neighboring zones.
It was decided that a plane passing through the inferior margin of the left orbit (the point called the left orbitale) and the superior margin of each ear canal or external auditory meatus, a point called the porion, was most nearly parallel to the surface of the earth at the position the head is normally carried in the living subject.

There are two openings of the thoracic cavity, a superior thoracic aperture known as the thoracic inlet and a lower inferior thoracic aperture known as the thoracic outlet. The thoracic cavity includes the tendons as well as the cardiovascular system which could be damaged from injury to the back, spine or the neck.
