BONE TISSUE
!
Tissue Components
Bone tissue is a type of connective tissue that contains lots of calcium and phosphorous salts. About 25% of bone tissue is water, another 25% is made up of protein fibers like collagen. The other 50% of bone tissue is a mixture of mineral salts, primarily calcium and phosphorous. !

Bone Anatomy
Bone Forms
Bones in the body are found in two basic forms, long bones and plates. Long bones of this kind are hollow on the inside. The inner space is called the medullary cavity. Bones are also covered by two membranes on the outside of the bone is the Periosteum. The inside of the bone, lining the medullary cavity is the Endosteum.
Bone Parts
!
The Epiphysis refers to the end of the bone, and the Diaphysis refers to the main shaft of the bone.
Each Epiphysis is connected to an adjacent bone using a structure called a joint. The ends of each bone are covered with articular cartilage which keeps the ends of the bones from grinding together when moving.

Because bone is made up of minerals and is hard, many people think that it is not living material. But a bone in a living animal consists of both living tissue and non-living substances. Within the "alive bone" are blood vessels, nerves, collagen, and living cells including:
•
osteoblasts (cells that help
