AP1
narrow slit between adjacent parts of bones;allows blood vessels/nerves to pass
fissure
opening for blood vessels, nerves, ligaments
foramen
Shallow depression
fossa
tubelike opening
meatus
furrow along the bone surface for blood vessels, nerves, tendons
sulcus
large, round portuberance having a small articular surface at the end of the bone
condyle
smooth, flat, slightly concave, or convex articulating surface
facet
rounded, articular projection that is supported on a neck (or construsted region) of bone
head
elongated projection or a prominent ridge
crest
a roughened projection above a condyle
epicondyle
long, narrow ridge or a boarder that is less prominent than a crest
line
sharp, slender projection
spinous process
very large projection
trochanter
variablly sized rounded projection
tubercle
variably sized projection w/ a rough, bumpy surface
tuberosity
longer in length then width
long bone
external layer of compact bone, spongy bone at ends
long bone
nearly equal in length/width
short bones
thick interior core of spongy bone, external compact bone
short bones
many flat, some have curved shape
flat bones
thin layer spongy bone "sandwiched" between compact bone
flat bone
dont fit into any category
irregular bone
vary in compact and spongy bone
irregular bone
small bones that form within tendons; protection against wear and tear
sesamoid bone
enlarged regions at proximal/distal ends; covered by articular cartilage
epiphysis
region where epiphysis and diaphysis meet
metaphysis
ossified cartilage
epiphysis line
exterior covering of dense vascular connective tissue membrane; cells that enable width growth of bone
periusteum
vain like stuctures throughout bone
nutrient artery
space within bone that hold yellow bone marrow
medullary cavity
lines cavity
endosteum
lies within spongy bone
red bone marrow
hard layer outside of bone
compact bone
mid area of bone; between metaphysis
diaphysis
in peristeum/endosteum; bone builders
osteoblasts
in peristeum/endosteum; bone breakers
osteoclasts
circular units that run parallel to the long axis of the bone
osteons
central canal of osteon; contains lymphatic vessels, blood vessels, and nerves that norish and serve the compact bone tissue
haversian canal
provide passage from the periosteum to the central canal
perforating (Volkmann) canals
concentric rings; similar to tree trunk rings
concentric lamellae
darkened area with thin lines extending between the lamellae
lacuna
mature bone cell
osteocyte
lines extending from lacuna; provide connection between blood vessels in the haversian canal to the osteocytes found within the lacunae
canaliculi
they fill the space between the osteons
interstitial lamellae
