1. Examples

   • Diaphysis of long bones
     • Metaphysis and epiphysis of long bones Short, flat, and irregular bones

2. Bone anatomy. Bone is made up of compact bone, cancellous bone, and bone marrow.

   • Compact bone forms the outer layer of bone.
   • Cancellous bone is found mostly at the ends of bones and contains red marrow.
   • The bone marrow is in the center of most bones and has many blood vessels.

3. There are two types of bone marrow: red and yellow.

   • Red marrow contains blood stem cells that can develop into red blood cells, white blood cells, or platelets.
   • The yellow marrow is made up, for the most part, of fat.

4. Bone tissue is a variety of specialized connective tissue, in which the extracellular matrix is mineralized, which gives it the hardness and resistance characteristic of this tissue.

   • The bone matrix contains type I collagen, type V collagen, glycosaminoglycans, glycoproteins, and sialoproteins.
