| Question | Answer |
|---|---|
| Diaphysis | main portion (shaft) surrounds medullary cavity – fat storage |
| • Epiphyses | enlarrgd ends of bone, coveerred in thin layer of cartilage, compact & spingy bone, certain bones – blood cell production takes place |
| • Periosteum | dense, white fibrous out covering bone |
| articulatioon - joint | - connection between two bones |
| abduction | movement of limb away from midline of body (spine) |
| adduction | movement of limb towards from midline of body (spine) |
| rotation | movement of a bone around its long axis |
| flexion | movement that decreases the angle between bones |
| extension | movement that increases the angle between bones |
| fibrous capsule | outer layer, attached to periosteum flexibility permits movement strength resists dislocation holds bones together |
| synovial membrane | inner layer lines joint cavity |
| synovial fluid | fills synovial cavity lubees joint keep bones from making contact |
| articular cartilage | covers the articulating surfacees of bone prrovide smooth surface |
| articular disc | dividee synovial capsule into 2 |
| spongy bone tissue | trabeculae -thin bony plates bone cells occupy space nerves & blood vesseels pass through spaces |
| bursae | Little sacs of synovial fluid - Only in some joints Prevent friction between - Bone and ligament/tendon - Bone & skin (where bone is near body surface) |
| Accessory ligaments | Fibrous tissue that attaches bone to bone Holds bone together @ joint |
| Synovial joint: | a freely moveable joint |
