compact bone
epiphyses, diaphysis of logn bones surface of short bones, plates of the bones
trabecular
aka cancellous, spongy
most bulbous epiphyses, lining of marrow cavity, core of short bones, diploë of flat bones
intramembranous ossification
forms directly within mesenchym
endochondral ossification
bone replaces hyaline cartilage
periosteum
outer covering of dense irregular CT
endosteum
lining of the cavities in bone, single layer
lacunae
spaces within matrix occupied by osteocytes
bone matrix
amorphosu mineralized ground substance and collagen fibers
outer circumferential
two or more layers of matric with lacunae arranged parallel to each oher located just deep to the periosteum
innercircumferential
two or more layers of matric with lacunae arranged parallel to the inner circumference of the bone located jsut deep to the marrow cavity
concentric
layers of matrix and lacunae that surround the central cnala of each osteon in concentric circles
interstitial
remnants of remodeled osteons found between complete osteons
canaliculi
fine channels radiating from each lacunae, connecting lacunae in adjacent lamellae
central canals
at the center of each osteon, containing the blood supply to the osteon
Volkmann’s (perforating) canals
enter bone and form connections perpendicula to the central canals; carry nutrient blood vessels to the bone
