Functions Of The Skeleton The human skeleton has 6 main functions that provide the body with good health. They are as follows: Support - our skeleton provides shape and support to our body which gives our body its shape, without this function our body would simply collapse. Movement - it aids our body to move by giving a framework to the attached muscles which then allows different movements at different joints. Movement is therefore powered by the skeletal muscles. Protection - the skeleton provides protection to many important organs. The skull protects the brain, eyes and ears. The vertebrae protects the spinal cord from any damage. The rib cage prevents any damage to the lungs, hearts and major blood vessels. The illium are there to protect the digestive system. Blood cell production – the skeleton is the place of haematopoiesis which is produced in the red bone marrow. Storage – bone tissues stores various minerals such as calcium and phosphorus, they release these minerals into the body when required. Leverage - this is the function which gives the body movement by making the bones act as levers. These levers are responsible for changing the direction of force created by the muscles in our body. Endocrine regulation¬¬¬¬¬¬ – the cells in the bones release a hormone known as osteocalcin which helps regulate glucose levels and fat deposition. On top of spiking up the production of insulin and reducing stores of fat it also increases the secretion of insulin. Skeletal System The skeletal system consists of 206 bones and is made up of the axial and appendicular skeletons. The axial skeleton is the central line of the body which consists of the cranium, vertebral column and rib cage. It is for... ... middle of paper ... ...em releases energy without the need of oxygen. It is broken down very quick and utilized to turn ADP into ATP. This energy system is very useful for quick and short bursts activities of 10 seconds such as the long jump and javelin. Creatine phosphate is limited in muscles for that reason most athletes use supplements to increase their creatine phosphate in the body. Lactic acid energy system also gives out energy without the need of oxygen. Energe is developd from the break down of glucose from glycogen and blood sugar. However the glycogen isn’t fully broken down and the process is known as anaerobic glycolysis, which leaves something known as latic acid. As lactic acid gather in the muscles, the muscles get weaker and fatigued. This energy system is use-able for about 2 minutes which makes it suitable for events such as the 100m swimming and the 400-800m run.
