| Question | Answer |
|---|---|
| Long Bone | A bone that is longer than it is wide, has a shaft plus two ends |
| short bone | a bone that is rough and cube shaped |
| flat bone | a bone that is thin flattened and usually curved |
| irregular bones | complicated shapes that do not fit in any other classes, vertebrae, hip |
| sesamoid bones | shaped like a sesame seed, special type of bone that forms in a tendon (patella) |
| Projections | muscle attachment |
| tuberosity | large rounded projection may be roughened |
| crest | narrow ridge of bone prominent |
| line | narrow ridge of bone less prominent than a crest |
| epicondyle | raised are on or above a condyle |
| spine | sharp slender often pointed projection |
| head | bony expansion carried on a narrow neck |
| facet | smooth nearly flat articular projection |
| ramus | handlelike bar of bone |
| meatus | canal like passageway |
| sinus | cavity within a bone filled with air and lined with mucous membrane |
| fossa | shallow basinlike depression often serving as an articular surface |
| groove | furrow |
| fissure | narrow slitlike opening |
| foramen | round or oval opening through a bone |
| diaphysis/ephiphysis | bone ends |
| periosteum/sharpeys fibers | glistening white dbl layer memebrane which surround entire bone surface except the joint |
| osteoblasts | bone forming cells which secret bone matrix and bone destroying cells |
| articular cartilage | hyline carilage covering bone ends at movable joints |
| epiphyseal plate/line | dis of hyaline cartilage that grows during childhood to lengthen the bone |
| medullary cavity | yellow fat cavity |
| red marrow | found within trabecular cavities of long bones and in the diploe of flat bones |
| endosteum | connective tissue connecting internal bone surfaces |
| trabeculae | thin plate of bone in spongy bone |
| haversian canal | runs through the core of each osteon and contains small blood vessels and nerve fibers |
| osteon | structural unit of compact bone runs parallel to the long axis of the bone |
| volkmann's canal | lie at right angles to the long axis of the bone connecting blood and nerves of the periosteum to those in the central canal |
| lucunae | small hollow depressions found at the junctions of the lamellae |
| lamellae | layer of bone matrix in the osteon of a bone |
