How many bones of the skeleton are there
206
Skeletal system organized into two divisions
axial and appendicular
composed of the bones along the central axis of the body, which are commonly divided into three regions—the skull, the vertebral column, and the thoracic cage.
Axial skeleton
includes the bones of the upper and lower limbs, and the girdles of bones that attach the upper and lower limbs to the axial skeleton. The pectoral girdle consists of bones that hold the upper limbs in place, whereas the pelvic girdle consists of bones that hold the lower limbs in place
Appendicular skeleton
fibrous joints that connect the bones of the cranium
Sutures
sagittal suture connecting the parietal bones of the skull, lamboid suture connecting the occipital bone with the parietal bones
Examples of sutures
When does the coronal suture usually close
First to close, 20s-30s
When does the sagittal usually close
30s or later
When does the lambdoidal usually close
Usually 40s
