 Vertebral Column | The main trunk of the body is supported by the spine, or vertebral column, which is composed of 26 bones, some of which are formed by the fusion of a few bones |
| The vertebral column from superior to inferior | 7, cervical(neck), 12 thoracic and 5 lumbar vertebrae as well as a sacrum. |
| Contains 12 pairs of ribs attached posteriorly to thoracic vertebrae and anteriorly either directly or via cartilage to the sternum (breastbone). | axial skeleton |
| Form the thoracic cage, which protects the heart and lungs. | ribs and strernum |
| The skull | consists of 22 bones fused together to form a rigid structure which houses and protects organs such as the brain, auditory apparatus and eyes. |
| Forms the major internal support of the appendages-the upper and lover extremities (limbs). | appendicular skeleton |
| Axial Skeleton- # of bones | 80 |
| Skull- # of bones | 22 |
| Ossicles (malleus, incus and staples)- # of bones | 6 |
| Vertebral column- # of bones | 26 |
| Ribs- # of bones | 24 |
| Sternum- # of bones | 1 |
| Hyoid- # of bones | 1 |
| Upper extremities- # of bones | 64 |
| Lower extremities | 62 |
| Bones are encased by a | periosteum, a connective tissue sheath. |
| Lies within the periosteum, forms the outer region of bones, and appears dense due to its compact organization. | Compact Bone |
| Consist of bars, spicules or trabeculae, which forms a lattice meshwork, found at the ends of long bones and the inner layer of flat, irregular and short bones. | Spongy bone |
| The cell of bones are | osteocytes, osteoblast and osteoclasts |
| Osteocytes | in compact and spongy bone are similar in structure and function. |
| Osteoblast | cells which form bone matrix, surrounding themselves with it, and thus are transformed into osteocytes. |
| Osteoclasts | cells found during bone development and remodeling. |
