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.

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.

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.

Blood Cell Production: Both red and white blood cells are produced in

the bone marrow. The bones also store minerals for other functions.

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.
