In each shoulder: the clavicle (collarbone)Īnd scapula (shoulder-blade) three in eachĪnd the radius and ulna (forearm bones) eight carpals in each wrist įive metacarpals in each palm and 14 phalanges in the digits of each hand (two in each thumb and three in each finger). The shoulders and upper limbs are made up of 64 bones. The appendicular skeleton is joined to the axial skeleton at the two girdles. Girdles – the pectoral girdle (or shoulder)Īnd their attached limb bones, which comprise the upper and lower extremities. The appendicular skeleton consists of 126 bones and includes the two limb (the rib-cage) around the heart and lungs. Which are attached at the front to the sternum, forming a protective cage The vertebrae are 12 pairs of ribs, most of Stacked on one another to provide a flexible column that surrounds and protects The skull is attached to the top (superior end) of the spinalĬolumn, also called the spine or backbone. The brain the rest are bones of the face,Įar, and the hyoid bone, which is suspendedĪt the back of the jaw by muscles and a ligament Of the 28 bones in the skull, 8 form the cranium that encases TheyĬolumn, ribs, and sternum (breastbone). The 80 bones of the axial skeleton form the vertical axis of the body.
The human skeleton is divided functionally into an axial skeleton, which supports the main body axis, and an appendicular skeleton, which supports the arms and legs. The type and amount of movement they allow. The individual bones of the skeleton are connectedīy three types of joints, which differ in If each of the nine fused vertebrae of the sacrum and coccyx are countedĪs independent bones). A normal adult human skeleton consists of 206 named bones (or 213 The skeleton is a supportive and protective structure in humans and other animals, against which the force of muscles acts.
