Human Skeleton

For humans the skeleton is a large part to the structure of the body because of all its required functions which all help to maintain the body in a safe and secure state. The human skeleton is made of 206 bones which are specifically developed and designed to perform several basic functions. At birth the human skeleton is made up of 275 different bones and as the body matures some of the bones fuse together leaving only 206 bones in the adult body. The skeleton is the internal structure that holds the human body up and with the help of the muscular system allows us to move. The skeleton includes several functions which are vitally important and essential for participation and contribution towards physical activity and movement. Without other components the skeleton would not be able to perform its functions correctly because it needs to combine with ligaments and joints otherwise it wouldn't be able to achieve the following functions:


The skeleton helps to provide a rigid and inflexible framework to the body which in turn gives the body its shape and also provides suitable positions for attachment of skeletal muscle.


The skeleton provides intensive protection for all the body's internal organs to prevent any damage which occur and cause serious injury for even death. Examples of protection ain the body where the skeleton protects vital organs are:

* Brain

The brain is major organ in the body because it is the main part which makes the body's nervous system because without the nervous system the human body wouldn't be alive due to all the information processed is done in the brain and all movement is decide and told to be carried out by the brain. The cranium is the structure of flat bones which is also well known as the skull. The skull is an extremely important part of the skeletal system because it protects the brain from damage and injury.

* Spinal Cord

The spinal cord is the motorway for information to be sent around the body it is the main link up between the brain and the rest of the body so if it was to be damaged the information wouldn't be able to get sent to the brain which means it would stop any movement occurring because before any movement is achieved the brain has to have the required information sent to it from the spinal cord and nerves. The Vertebral column is responsible for the protection of the spinal cord because the spinal cord travels through the vertebral column and so if the spine is damaged it would also cause injury to the spinal cord resulting in major problems.


The skeletons bones help to provide a large surface area for the attachment of the body's muscles which happen to be the main factor of movement.

The long bones are also helpful because they act as a system of levers which the muscles can pull to allow and produce movement. There are 3 types of joints that connect bones; these are fixed joints, mobile joints and ball and socket joints. Fixed joints are the joints that are between the bones in the skull. Mobile joints are like hinge joints of the elbow or pivotal joint like the joint between the first and second vertebrae. This allows the head to turn from side to side. Ball and socket joints allow the widest range of movement like the shoulder and hip joints.

Blood cell production

Within the bones of the skeleton bone marrow produces both red and white blood cells. Red blood cells are usually produced in the ends of long bones such as the humerus and the femur and in some flat bones such as the pelvis and the sternum. While white blood cells are mainly produced in the shafts of the long bones.

Mineral Storage

The bones of the skeleton also happen to be able to store vital minerals such as calcium and phosphorus which can be distributed to other parts of the body when in ...
