1.	Describe the structure and function ofmammalian bone
Answer» Bone is not uniformly solid, but includes a toughmatrix. This matrix makes up about 30% of the bone and the other 70% is of salts that give strength to it.The matrix is made up of between 90 and 95%collagenfibers, and the remainder isground substance.The primary tissue of bone,bone tissue(osseous tissue), is relativelyhardand lightweight. Its matrix is mostly made up of a composite material incorporating the inorganic mineralcalcium phosphatein the chemical arrangement termed calciumhydroxylapatite(this is thebone mineralthat gives bones their rigidity) andcollagen, an elastic protein which improves fracture resistance.The collagen of bone is known as ossein.Bone is formed by the hardening of this matrix around entrapped cells. When these cells become entrapped from osteoblasts they become osteocytes.
