The regions of the skeleton
The skeleton can be divided into 7 different sections – click through this presentation using the tabs below, to see what these 7 sections are.
2
The Skull Made up of cranium (8 fused bones) and the facial bones (14 bones). The mandible (jaw bone) is the only truly moveable bone of the skull.
3
The Spine Consists of 33 vertebrae divided up into 5 distinct parts.
4
The Pectoral Girdle Consists of 2 shoulder blades (scapulae) and 2 collar bones (clavicles). These bones articulate with one another, allowing some degree of movement.
5
Upper Limb Consists of 3 parts: the upper arm (humerus); lower arm (radius and ulna); and hands (carpals, metacarpals, and phalanges).
6
The Thorax Consists of 12 pairs of ribs all of which attach to the spine and the sternum. The top 7 ribs are known as true ribs as they attach directly to the sternum by costal cartilage. The bottom 2 are known as floating ribs as they do not attach to the sternum.
7
The Pelvic Girdle Consists of 2 large, sturdy hip bones that are fused together. Each hip bone consists of 3 fused bones namely the ilium, ischium and the pubis.
8
The Lower Limb Consists of the upper leg (femur); lower leg bones (tibia and fibula) and feet (tarsals, metatarsals and phalanges).
