The Skeletal System The functions of the Skeleton are to: * Provide Protection * Movement * Blood Production * Support * Shape * Mineral Production Definitions of the functions: Protection: The skeleton is designed in such a way that the delicate parts of the body are protected. These parts are major organs, the brain is protected by the skull, the lungs and heart are protected by the ribs and the vertical column protects the spinal cord. For example you will see this happen in many sports such as boxing, the skull protects the brain from impact of a punch during a fight. [IMAGE] Support/ Shape: The skeletal system gives the human body structure. It supports the internal organs that are held within the body in a network of tissue. Bones give us form. In sports support and shape are also used for example in a rugby scum, to body needs to be placed in such a way to keep the back aligned. [IMAGE] Movement/ Attachment: The skeleton is jointed to allow movement. A joint is an articulation of two or more connecting bones, providing us with either stability or movement. Muscles are attached to our bones by tendons, and ligaments attach bone to bone. Movement is very important to any sports it allows us to make the certain movements needed to succeed. For example when striking the ball in football, a range of muscles and bones work together to allow for this movement. [IMAGE] Blood Cell Production: Both red and white blood cells are produced in the bone marrow. The bones also store minerals for other functions. [IMAGE] The Skeleton: The human skeleton consists of 206 bones. Humans are actually born with more bones (about 300), but many fuse together as a child grows up. These bones support the body and allow movement. Front View Back View [IMAGE] [IMAGE]
