Structure of the skeleton
The skeleton is made up of two hundred and six bones, but over three hundred bones when a
infant. This is due to the bones being cartilage; they then change into bone in the first year of
life. This process is called ossification. There are two different types of bones these are
compact and spongy. The skeleton has a major role in the human body. The functions of the
·Support the skeleton provides a framework for soft tissues such as muscles, tendons and
ligaments to attach too. Without a skeleton we would be a pile of jelly. This function also
keeps the body in the right position.
·Protection- the bones protect vital organs such as the cranium protects the brain from any
impact, the ribs and sternum protects the heart and lungs and the vertebrae column protects the
spinal cord which sends messages from the brain to other parts of the body.
·Attachment for the skeletal muscles- some parts of the skeleton allows muscles to attach
too it for example the origin (where the muscle is attached to a stationary bone) of the bicep is
the scapula and the insertion (the point where the muscle is attached to the bone that moves) is
·Leverage- the skeleton allows movement where bones join for example the femur, patella
(floating) and tibia allows the knee to move. Muscles are attached to the bone by tendons.
Tendons are a non-elastic type fibre.
·Store of minerals-some bones in the skeleton allows minerals to be stored. Blood cells (red
and white) are also produced in the marrow of long bones such as the femur.…read more
