Within about 48 hours after the fracture stem cells from the endosteum of the bone differentiate into chondrocytes which then secrete a fibrocartilaginous matrix between the two ends of the broken bone. OBs help to build bone by depositing collagen matrix whereas OCs serve to degrade bone. C When bone modeling occurs bone mass increases.

E All of these answers are correct. There is no cartilage involved in bone repair but there is in bone development. Bone formation occurs by osteoblasts secreting an organic matrix osteoid and then mineralizing the matrix.

Up to 10 cash back Bone remodeling is a key process in vertebrate organisms since it is responsible for maintaining skeletons integrity. The process of bone remodeling occurs throughout life via cells such as osteoblasts OBs and osteoclasts OCs possibly modulated by the influence from OCs distributed throughout the bone matrix.

Chondrocytes enlarge and die leaving struts within the cavity. Then other bone cells called osteoblasts create new bone. First special bone cells called osteoclasts break down bone.

E All of these answers are correct. To gain a better understanding about these conditions bone remodeling has. Osteoclasts are involved in bone development but not in bone repair.

The change is opposite that of negative feedback and B. The medullary cavity has a delicate membranous lining called the endosteum end- inside. 1 2 4 3.

Bones are remodeled continually in response to changes in blood calcium levels and the pull of gravity and muscles on the skeleton. OCs move to a surface of bone matrix and resorb the bone. When bone remodeling occurs bone mass may stay the same.

Remodeling occurs as bone gets thicker and establishes secondary ossification centers. Seen here as density. A Fibrocartilage degenerates where the two broken ends of the bone were once together.

When the remodeling process is skewed such that over time there is more eating than replenishing you get osteoporosis. The outer surface of the bone is covered with a fibrous membrane called the periosteum peri around or surrounding. Estrogen via decrease in RANKL stimulates bone production anabolic and prevents resorption.
