Calcification is the process of deposition of mineral salts on the collagen fiber matrix that crystallizes and hardens the tissue. The mineral salts primarily include hydroxyapatite, a mineral formed from calcium phosphate. It contains specialized cells and a matrix of mineral salts and collagen fibers. For example, spongy bone tissue is found in the inner layer of bones and contains blood vessels to deliver nutrients and remove waster from bone cells.īone, or osseous tissue, is a connective tissue that constitutes the endoskeleton. However, as a student of biology it is important to understand the types of bones and bone tissues as well as their functions because this basic part of anatomy is an excellent example of form follows function.

Some muscles allow us to open our mouths and bite down with force. Muscles attach to the skull at different locations. The combination of compact and spongy bone is important because flat bones have numerous muscle attachment points that pull in different directions, so they need to be able to withstand forces in different directions.įor example, the skull is made of flat bones and irregular bones. ![]() The hard outer layer provides protection from direct forces, while the spongy bone center allows these bones to absorb forces coming from different directions as well. ![]() Red bone marrow is contained within the spongy bone. These bones are constructed in a sandwich-like manner, with hard compact bone on the outside and spongy bone on the inside. The skull, ribs, and sternum are all made from flat bones. Flat bones are a type of bone that protects internal organs. ![]()
