|
|
Are the sesamoid and wormian bones included in the bone count of 206?
|
except for the patellas, no.
Because they vary in number and location in different individuals |
|
diaphysis
|
Long Bone
or shaft. Smooth surface, which is composed of compact bone. |
|
peristeum
|
Long Bone
or fibrous membrane covering surface. The many fibers of the periosteum penetrate into the bone |
|
epiphysis
|
Long Bone
The end of the long bone |
|
articular cartilage
|
covers the epiphyseal surface in place of the periosteum. Composed of glassy hyaline cartilage, it provides a smooth surface to prevent friction at joint surfaces
|
|
epiphyseal plate
|
Long bone
Child - thin area of hyaline cartilage that provides for longitudinal growth of the bone during young |
|
epiphyseal lines
|
Once the long bone has stopped growing (epiphyseal plate), the thin hyaline cartilage is replaced with bone and appear as thin remnants
|
|
yellow marrow
|
Long bone
Adults - central cavity of the shaft (medullary cavity) is a storage region for adipose tissue |
|
red marrow in adults
|
long bones
confined to the interior of the piphyses, where it occupies the spaces between the trabeculae of spongy bone |
|
red marrow - child
|
long bone
this area is involved in forming blood cells. Is found in the marrow cavities |
|
endosteum
|
long bone
covers the trabeculae of spongy bone and lines the canals of compact bone. Contains both osteoblasts and osteoclasts. |
|

|
|
crest
|

|
|
trochanter

line
|
narrow ridge of bone; less prominent than a crest
|
|
tubercle
|
small rounded projection or process
|
|
