Terms #2 Flashcards
perforating fibers
bundles of collagen fibers (sharpey fibers) straighten the attachment of the tendons or ligaments to the bone
sinuses
some flat and irregular bones of the scull have these open air-filled spaces which are lined by a mucus membrane
intramembranous ossification
takes place in connective tissue membranes- produces woven bone
endochondral ossification
takes place in cartilage-
fontanels
larger membrane-covered spaces between the developing skull bones that haven’t been ossified yet
hypertrophy
to enlarge
calcified cartialge
when hydroxyapatite crystals are formed in the cartilage matrix
zone of resting cartilage 1
nearest to the epiphysis, contains randomly arranges chondrocytes that don’t divide rapidly
zone of proliferation 2
produces new cartilage through interstitial cartilage growth
zone of hypertrophy 3
chondrocytes produced in the zone of proliferation grow
zone of calcification 4
very thin and contains hypertrophied chondrocytes and calcified cartilage matrix
basic multicellular unit (BMU)
bone remodeling includes this- temporary assembly of osteoclasts and osteoblast that travel across the bone getting rid of old bone matrix and replacing it
hematoma
localized mass of blood released from blood vessels but confined within an organ or space
callus
mass of tissue that forms at a fracture cite and connects the broken ends of the tissue (internal forms between the ends of the broken bone) (external forms around the opposing ends of the fragments)
open fracture
when the bone protrudes the skin
