Class of Bones

compact bone smooth and homogenous
spongy bone composed of small trabeculae (bars) of bone and lots of open space
long bones are much longer than they are wider, generally consisting of a shaft with heads at either ends
short bones typically cube shaped, and they contain more spongy bone than compact bone
flat bones generally thin, with two waferlike layers of compact bone sandwiching a layer of spongy bone between them
irregular bones bones that do not fall into one of the proceeding categories
tuberosity large rounded projection; may be roughened
crest narrow ridge of bone; usually prominent
trochanter very large, blunt, irregularly shaped process (the only examples are on the femur)
line narrow ridge of bone; less prominent than a crest
tubercle small rounded projection or process
epicondyle raised area on or above a condyle
spine sharp, slender, often projected pointed
process prominence or projection
head bony expansion carried on a narrow neck
facet smooth, nearly flat articular surface
condyle rounded articular projection
ramus armlike bar of bone
sinus space within a bone, filled with air and lined with mucous membrane
meatus canal like passageways
fossa shallow, basinlike depression in a bone, often serving as an articular surface
groove furrow
fissure narrow, slit like opening
foramen round or oval opening through a bone
periosteum fibrous membrane covering a long bone
diaphysis shaft of a long bone
endosteum inside lining of a bone
articular cartilage covers the epiphyseal surface in place of periosteum at joint locations
epiphysis end of a long bone
haversian canal runs parallel to the long axis of the bone and carries blood vessels, nerves, and lymph vessels through the bony matrix
lamellae rings of calcified extracellular membrane
lacunae mature bone cells in chambers arranged in concentric circles around the central canal
canaliculli tiny canals radiating outward from a central canal to the lacunae of the first lamellae and then from lamallae to lamallae
