Functions of the skeletal system
There are five main functions of the skeletal system. To protect, to support, movement, cell production and storage.
The skeletal system protects delicate and important organs from harm. An example of this is the ribcage. This protects your heart and lungs from anything that tries to harm it. Another example is the brain. The brain is protected by the skull.
The skeletal system also provides support for the body as it acts as a framework giving the body its shape. This helps the body go against gravity.
Muscles are attached to the bones by tendons which allows movement in the body. The bones allow the muscles to contact meaning movement is possible. Where two …show more content…

Minerals such as calcium and phosphorus are stored in the bones. If the blood levels of these minerals drops excessively then some of the stores within the bone can be released. Fat can also be stored in the bones.
Three types of cells are produced by the bone marrow inside the bones. Red blood cells, white blood cells and platelets. The red blood cells help carry oxygen from the lungs to the muscles. The white blood cells fight against infections, while the platelets help clot the open wounds.
Structure of the skeletal system
The axial skeleton consist of 80 bones and is composed of eight parts. The skull bones, the ossicles of the middle ear, the hyoid bone, the rib cage, sternum and the vertebral column. This image shows the axial skeleton

For example, the cranium is you skull. This protects the brain from any harm. Another example of a major bone are the ribs. They are located in your chest area and protect the heart and lungs.
The humerus is a long bone located in the arm or forelimb that runs from the shoulders to the elbow. It connects the scapula and the two bones of the lower arm, the radius and ulna, and consists of three sections.
The radius or the radial bone is one of the two largest bone located in the forearm. It extends from the lateral side of the elbow towards the thumb side of the wrist. It is a long bone that is prism shaped and slightly curved.
The ulna is the second bone in your arm, and is next to the radius. It extends from the elbow to the wrist and runs parallel to the radius.
The scapula is also known as the shoulder blade. It is the bone that connects the humerus with the clavicle. It is a paired with the scapula on the other side of the body. It is a flat bone that forms the back of the shoulder girdle.
The pelvis is located in the lower part of the body between the thigh and the abdomen. In mammals, the bony pelvis has a gap in the middle. This gap is significantly larger in females than in males. This is where babies pass through when they are
