SKELETON: anterior view of the axial (bone colored) and appendicular (blue colored) skeleton
The bony framework of the body consisting of 206 bones: 80 axial or trunk and 126 of the limbs (appendicular). This number does not include teeth or sesamoid bones other than the patella. See: illustration; table

appendicular skeleton

The bones that make up the shoulder girdle, upper extremities, pelvis, and lower extremities.

axial skeleton

Bones of the head and trunk.

cartilaginous skeleton

The part of the skeleton formed by cartilage; in the adult, the cartilage of the ribs and joints. Cartilage is more flexible and resistant to resorption due to pressure than bone.
