Structure and Function of Bone

primitive embryonic cells

when mineral replaces previously formed cartilage and creates bone

35%

65%

the cartilage separating the epiphysis from the diaphysis in the early stages of development

bone cells that deposit new bone

bone cells that can dissolve bone, secreting enzymes that split up the substance in bone and placing them into the surrounding fluids

the long shaft of the bone

an extreme end at each end of the bone

a hallowed interior of the shaft where yellow bone marrow produces fat cells, or red bone marrow produces blood cells

lines the marrow canal

softer bone in the interior where blood vessels can easily distribute their nutrients to the bone cells

outer, tougher bone giving bone its strength

tissue covering the epiphysis in a thin layer of cartilage

the length is greater than the circumference of these bones

the thickness of these bones is minimal

oddly shaped bones for various attachments of muscles and movement

cube-like in physical structure

small, round, and flat bones that develop inside tendons to offset stresses on those joint sites
