Skeletal System
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 |
