Cross-section of a femoral head. Bone tissue is a type of dense connective tissue and hard. It has a honeycomb-like matrix internally, which helps to give the bone cells. Osteoblasts and osteocytes are involved in the formation and mineralization of bone. 

Modified osteoblasts are the lining cells that become form a protective layer on the bone surface. The mineralized matrix of bone tissue has an organic component of the main collagen called ossein and an inorganic component of bone mineral made up of various salts.

Bone tissue is mineralized tissue of two types, cortical bone, and cancellous bone. Many more types of tissue found in bones include bone marrow, endosteum, periosteum, nerves, blood vessels, and cartilage. 

In the human body at birth, there are approximately 270 bones present, many of these fuses together during development, leaving a total of 212 separate bones in the adult, not counting numerous small sesamoid bones. The largest bone in the femur or thigh-bone and the smallest is the stapes in the middle ear.
