| Question | Answer |
|---|---|
| Arth-, Arthr- | joint |
| Carpus | wrist |
| Chond- | cartilage |
| -clast | to break |
| Cost- | ribs |
| Dont- | Teeth |
| Myel- | Bone marrow |
| Oss-, Osteo- | bone |
| syn- | union |
| Tarsus | ankle |
| exoskeleton | hard, outer skeleton that is outside the body, found in arthropods (insects, arachnids and crustaceans) and in molluscs with shells (clams and snails) |
| endoskeleton | skeleton embedded within the muscle, domestic animals contain the type of skeleton |
| functions of skeletal system | provides support, body form, works with muscle to perform body movements, and protects inner body organs |
| axial skeleton | bones of the skill, rids (costae), vertebrae, and sternum |
| appendicular skeleton | bones of the appendages or limbs |
| heterotrophic bones | (splanchnic or visceral bones) bones embedded in the organs |
| os rostrale | bone in the snout of the pig |
| ossa cordis | bones in the heart of cattle, sheep, and goats |
| os phrenis | bone in the diaphragm of camels |
| ossa penis | bones in the penis of carnivores (dogs and cats) and rodents |
| scleral rings | round bones found in the eyes of birds |
| hyoid apparatus | found in the tongue of avians |
| origin | the end of the muscle that is attached to a stationary part of bone |
| insertion | the end of the muscle that is attached to a mobile section of bone |
| tendons | attach muscles to bone |
| ligaments | attach bone to bone |
| epiphysis | the two ends of long bone |
| diaphysis | the shaft of long bone |
| epiphyseal-diaphyseal plate | a growth region between the epiphysis and the diaphysis |
| endosteum | membrane lining the medullary cavity |
| periosteum | membrane covering the outer surface of the bone composed of connective tissue |
| medullary cavity | hollow area in the center of the bone where bone marrow is located |
| diploe | spongy bone |
| long bone | dumb-bell shaped, wide, expanded ends, narrow, cylindrical mid-section |
| elongated bone | costae (ribs), expanded ends, no medullary cavity (marrow space) |
| aborted bone | ulna of horse, one expanded end, rudimentary medullary cavity (in the proximal-extended end of bone), distal extremity small |
| flat bone | flat in two dimensions |
| typical flat bone | bones of skull, intramembranous, lighter weight bone |
| atypical flat bone | scapula, develops from cartilage, no diploe |
| short bone | cubicle in shape, typical short bones, sesamoid bones |
| typical short bones | human wrist and ankle, knee and tarsal, carpels |
| sesamoid | shaped like sesame seeds, bones that form in a tendon, patella |
| functions of short bones | reduce concussion, reduce friction |
| Irregular bone | bones of vertebral column, cervical vertebrae |
| Pneumatic bone | air (air packets/spaces/cavities) birds, excavation in skill (paranasal sinuses) |
| 5 types of bone | long bone, flat bone, short bone, irregular bone, pneumatic bone |
| How many cervical vertebrae do mammals have | 7 |
