S4W6V Flashcards
the marrow space in the shaft of a long bone
medullary cavity
a simple machine consisting of a rigid bar pivoted on a fixed point and used to transmit force, as in raising or moving a weight at one end by pushing down on the other
lever
a soft, fatty, vascular tissue in the interior cavities of bones that is a major site of blood cell production
marrow
cartilage that lines the joints
articular cartilage
flat bones, like the skull or jaw bone develop from clusters of condensed mesenchyme
intramembranous bone
the shaft of a long bone
diaphysis
layer of protective hard bone tissue surrounding every bone; composed of repeating units of osteon systems
compact bone
any bone that develops in and replaces cartilage
endochondrial bone
a growing bone contains a band of cartilage located at the ends of long bones, between the epiphysis and the diaphysis
epiphyseal bone
a part or process of a bone separated from the main body of the bone by a layer of cartilage and subsequently uniting with the bone through further ossification
epiphysis
a large multinucleate cell found in growing bone that resorbs bony tissue, as in the formation of canals and cavities
osteoclast
potential bone-forming cell; secretes collagen in which minerals in the bloodstream can be deposited
osteoblast
the formation of blood cells in the living body (especially in the bone marrow)
hematopoiesis
the dense fibrous membrane covering the surface of bones except at the joints and serving as an attachment for muscles and tendons
periosteum
newly formed bone cells
osteocyte
