| Question | Answer |
|---|---|
| hyaline cartilage | most abundant cartilage provides support through flexibility |
| elastic cartilage | contains many elastic cartilage, able to tolerate repeated bending |
| fibrocartilage | resists strong compression and strong tension. an intermediate between hyaline and elastic cartilage. |
| flat bones | thin and flattened, usually curved |
| long bones | longer than wide- a shaft plus ends |
| short bones | roughly cube-shaped |
| irregular bones | various shapes, do not fit into other categories |
| compact bone | dense outer layer of a bone |
| spongy (trabecular) bone | internal network of bone |
| osteocytes | mature bone cells; spider shaped |
| lacunae | small cavities in the solid matrix |
| caniliculi | thin tubes |
| diaphysis | "shaft" of bone |
| epiphysis | ends of a bone |
| blood vessels | well vascularized |
| medullary cavity | hollow cavity in the shaft of the bone; filled with yellow marrow |
| periosteum | fibrous membrane that covers the external surfaces of bones except at their articular surfaces |
| endosteum | membrane lining the medullary cavity of bone and other inner bone surfaces |
| central canal | runs through the core of each osteon |
| haversian canal | runs through the core of each osteon; lined by endosteum |
| volkmans canal | lies at right angles to the central canals and connects the blood and nerve supply |
| lamella | layer of bone matrix in which collagen fibers and mineral crystals run in a single direction |
| hematopolesis | blood cell formation |
