Location of blood formation | Medullary cavity |
Part of the skull that surrounds the brain | Neurocranium |
Part of the skull that makes up the face | Viscerocranium |
Slightly movable joint in the vertebrae | Modified symphysis |
Shock absorber in between the vertebrae | Intervertebral discs |
Only fibrocartilage | True symphysis |
Very flexible cartilage | Hyaline cartilage |
Very strong cartilage | Fibrocartilage |
Bones not on the median line - limbs | Appendicular skeleton |
Bones along the median line | Axial skeleton |
Bones that make up the shoulder - scapula, clavicle | Pectoral girdle |
Appears solid | Compact bone |
Appears spongy | Cancellous bone |
Growth plate in bones - allows growth in length | Epiphyseal plate |
Water - 25% - absorbs shock minerals - 45% - calcium and phosphorus organic matter - 30% - collagen | Bone composition |
Bone stem cell - stimulated to differentiate | Osteoprogenitor |
Bone builder - secretes collagen for matrix | Osteoblasts |
Mature bone cells within the matrix | Osteocytes |
Bone formation from tissue other than skeletal | Heteroplastic |
