a connective tissue in which the matrix is hardened by the deposition of calcium phosphate and other minerals
the process in which calcium, phosphorus, and other minerals crystallize on the collagen matrix of a growing bone, hardening the bone the same as calcification
the process in which calcium, phosphorus, and other minerals crystallize on the collagen matrix of a growing bone, hardening the bone the same as mineralization
small spaces between the lamellae which contain osteocytes
small hair-like canals extending from the central canal. Allow for diffusion of nutrients, waste products, hormones, etc. to lacunae.
bones that are thin and flattened, and usually somewhat curved (eg the sternum, scapulae, ribs, and most skull bones)
the most common class of bone in the body, long bones have a well-defined shaft (the diaphysis) and two well-defined ends (the epiphyses).
the bodily system that consists of the bones, their associated cartilages, and the joints, and supports and protects the body, produces blood cells, and stores minerals.
cube-shaped bones of the wrist and ankle. Bones that form within tendons (e.x., patella)
bone that doesn't fit in any other category;
mostly spongy bone with thin compact outer layer; ex, vertebrae, facial bones
dense, hard layers of bone tissue that lie underneath the periosteum
mature bone present in normal adult stages; collagen fibers are perfectly arranged in a parallel pattern
cavity within the shaft of the long bones filled with bone marrow
the hollow central cavity that extends the length of the diaphysis.
layer of Bone tissue having many small spaces and found just inside the layer of compact bone
lighter, less strong bone that is found in the ends and inner portions of long bones; also called spongy bone
the shaft of a long bone
the end of a long bone
thin hyaline cartilage layer that covers epiphyses of bones in synovial joints
an opening in the compact bone that allows for the passage of a nutrient artery and a nutrient vein into the medullary cavity.
a dense fibrous membrane covering the surface of bones (except at their extremities where the articular cartilage is located "joints") and serving as an attachment for tendons and muscles
tufts of collagen fibers that extend from its fibrous layer into bone matrix, which secure periosteum to underlying bone
hundreds of connective tissue securing periosteum to underlying bone
vascular membrane that lines the inner surface of long bones
a band of carilage (hyaline) found between the diaphysis and epiphyses of long bones during childhood and adolescence. Cell proliferation in the middle of the eiphyseal plate essentially forces the diaphysis and epiphyses further apart, while the older cartilage at the endes of the plate is replaced with bone. This is waht allows bone growth during childhood. The epiphyseal plate gets thinner and thinner the older a person gets, until finally it fuses ( the diaphysis and epiphyses connect) in late adolescence, preventing further elongation of the bones.
the internal layer of spongy bone in flat bones
supporting bundles of bony fibers in cancellous (spongy) bone
stem cells that develop in osteoblasts-- found inside of the periosteum and endosteum
stem cells divide to produce daughter cells that differentiate into osteoblasts
bone forming cells
former osteoblasts that have become trapped in the matrix they have deposited. they reside in tiny cavities called lacunae
large cells that resorb or break down bone matrix, releasing calcium ions into the blood
a crystallized mineral salt in bone matrix that forms when calcium phosphate combines with calcium hydroxide
a combination of two basic structural materials. Bone is considered to be in this class of materials
