Appendicular skeleton consists of bones of the limbs (arms, hands, legs, feet) and the bones that connect the limbs to the axial skeleton. Bones of the skull: protect the brain. Facial bones: provide points of attachment for facial bones as well as openings for the digestive tract. Vertebrae: support and protect the spinal cord.
