Imagine for a moment that people did not haveskeletons. What comes to mind? Probably that each of us would be a little heap on the floor, much like a jel-lyfish out of water. Such an image is accurate and reflects the most obvious function of the skeleton: to support the body. Although it is a framework for the body, the skeleton is not at all like the wooden beams that support a house. Bones are living organs that actively contribute to the maintenance of the internal environment of the body.
The skeletal system consists of bones and other structures that make up the joints of the skeleton. The types of tissue present are bone tissue, cartilage, and fibrous connective tissue, which forms the ligaments that connect bone to bone.
