Spine


It is a column of vertebrae that each have a hole, overlapping each other forming a channel that houses the nerve or spinal cord.

It is divided into typical regions which are: cervical spinel (neck region), thoracic spine, lumbar spine, sacral column, coccyceal spine (coccyx).

Ribcage

It is formed by the thoracic region of the spine, external bone and ribs, which are 12 on each side, the first 7 being true (inserted directly into the sternum), 3 false (joining and then joining the sternum), and 2 floating (with free anterior ends, not attaching to the sternum).
