Expert Solution

1.Bone is a connective tissue it consists of three components,

           * Bone cells

                       Bone cells are divided into three types,

                                Osteoblast

                                          Osteoblasts are precursors of osteocytes which help in the formation of

                                           osteocyte or mature bone cell.

                                 Osteocytes

                                           Osteocyte is the mature bone cell and basic functional unit of bone.

                                  Osteoclast

                                            This cells result in bone resorption and remodelling.

            * Ground substance

                              It includes proteoglycans.glycoproteins,mineral components and water to

                              maintain bone rigidity and hydration.

            * Fibers

                      Fibers are type one collagen fibers that provide adequate tensile strength to the bone.

Unique qualities of bone

                 * Bones form a structural framework of the body to give a shape and support.

                  * It provide surface for attachment of ligaments,tendons and muscles.

                  * It protect the internal organs of the body from external injuries.

                  * Bone act as a store house of calcium and phosphorus.

                  * Bone marrow is the place where blood cells produced.

                  * Bones along with muscle make the body movements.

2. Bones response to injury,stress and aging

                    * Bone is a protective structure of the body from various type of injuries,stress

                       or compression but in case of severe injuries different types of fractures occur

                       based on which area of body affected ( eg;compression fracture of spine,green

                        stick fracture of wrist bone etc).

                   * Aging result in reduction of bone density and development of osteoporosis which

                     result in pathological fractures.

                   * Aging process affect the joints of bones and cartillage damage occur result in

                      osteoarthritis.
