Osteoblasts, which do not divide, synthesize and secrete the collagen matrix and calcium salts. These vessels and nerves branch off at right angles through a perforating canal, also known as Volkmann’s canals, to extend to the periosteum and endosteum. flat bones… Short Bones. The hydroxyapatite crystals give bones their hardness and strength, while the collagen fibers give them flexibility so that they are not brittle. Flat bones serve as points of attachment for muscles and often protect internal organs. Now they are ready to build their own labeled skeletons. It is generally an inherited condition, though it can be a symptom of other genetic disorders. Short bones are designated as those bones that are as wide as they are long.

A short bone is one that is cube-like in shape, being approximately equal in length, width, and thickness. Created. Spiral fracture is caused by a twisting force. The spaces of the trabeculated network provide balance to the dense and heavy compact bone by making bones lighter so that muscles can move them more easily. They are often challenging to treat, as it is difficult to set short bones and keep them stable while they heal. Human skeleton, the internal skeleton that serves as a framework for the body.

The surface features of bones vary considerably, depending on the function and location in the body. Woven bone: Woven bone is characterized by the irregular organization of collagen fibers and is mechanically weak.. Woven bone is found on the growing ends of an immature skeleton or, in adults, at the site of a healing fracture. Brachydactyly is known as shortening of the fingers and toes due to unusually short bones. Compact bone is dense so that it can withstand compressive forces, while spongy (cancellous) bone has open spaces and supports shifts in weight distribution. Other bone types include: long bones; short bones; irregular bones Compact bone is the denser, stronger of the two types of bone tissue (Figure 6.10). Start studying Essentials of Anatomy & Physiology: Chapter Five Review Questions Multiple Choice.
