Friday, February 20th, 2009The foundations of the body is the musculouskeletal system, which is made up of muscles, bones, joints, and their associated tissues. These are the areas most often injured in sports.
Bones
Bones make up the skeleton, which is the body’s framework. The skeleton has two main functions;
* Supporting the body
* Protecting important organs
Muscles
Muscles move the bones by shortening and lengthening in response to signals from th brain. The major muscle groups are the rotator cuff in the shoulder, quadriceps in the front of the upper arm, triceps behind the upper arm, and the calf muscles behind the lower leg.
