Function:
- Protection: The bones and joints help protect the brain and other delicate internal organs.
- Support: The bones and joints help provide a framework for the body. They specifically help the body maintain its upright position, which is essential for life.
- Blood Cell Formation: Blood cells are developed in the marrow of some bones ( hematopoiesis)
- Mineral Homeostasis: Some bones store minerals in them such as calcium and phosphorus.
- Storage: Again the bones can store certain minerals, but they can also store fats which are needed for chemical energy. The yellow marrow found in bones is home to adipose cells. Adipose cells are fat cells, and are a very important source of chemical energy.
- Movement/Leverage: The bodies bones and joints are similar to a simple machine. A lever is a simple machine that quickens speed of movement or force. The bones in the body (especially the long bones) are like levers, and the joints (where the bones meet) are like the fulcrums. Together they allow our bodies to move.
- Periosteum: This is the dense white sheath that covers the surface of the bone. This is also the part of the bone where muscles and tendons attach.
- Diaphysis (also known as the shaft): This is the portion of the long bone between the epiphysis.
- Medullary Cavity: This is a cavity of the bone (in the middle) filled with yellow, fatty marrow.
- Spongy Bone: This helps create the rigid part of the bone. This part of the bone isn't as dense, and therefore contains spaces so blood vessels and other nutrients can get to the bone.
- Compact Bone: Has little space within, and provides the bone protection and strength.
- Epiphysis: This is the end of a long bone, and is disconnected from the (diaphysis).
