appendicular skeleton

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

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.
