The muscle system is a very complex important system in our bodies. The muscle fibers are separated into three different groups. There is skeletal muscle, cardiac muscle, and smooth muscle. Skeletal muscle is the type of muscle that you would find around the skeletal system, and is the only type of muscle found in the muscular system. Main Functions Of Skeletal Muscles •Produce movement of the skeleton •Maintain posture and body position •Support soft tissues •Guard entrances and exits •Maintain body temperature |
Organization of Skeletal Muscles
There are three different layers of connective tissues in skeletal muscles. Epimysium is what separates the muscles from the surrounding tissues. Perimysium surrounds muscle fibers that are called fascicles. The endomysium surrounds individual muscle cells called muscle fibers. | |
ATP to ADP - Energy Release This is done by a simple process, in which one of the phosphate molecules is broken off, therefore reducing the ATP from 3 phosphates to 2, forming ADP (Adenosine Diphosphate after removing one of the phosphates {Pi}). This is commonly wrote as ADP + Pi.
When the bond connecting the phosphate is broken,energy is released.
While ATP is constantly being used up by the body in its biological processes, the energy supply can be bolstered by new sources of glucose being made available via eating food which is then broken down by the digestive system to smaller particles that can be utilized by the body.
On top of this, ADP is built back up into ATP so that it can be used again in its more energetic state. Although this conversion requires energy, the process produces a net gain in energy, meaning that more energy is available by re-using ADP+Pi back into ATP.

Integumentary System Relates to Muscular System
The integumentary system provides protection for the muscular system. If the integumentary system did not exist there is no way that the muscles could perform properly.
A disease that affects both the integumentary system and the muscular system is dermatomyositis. Dermatomyositis (DM) is a rare inflammatory muscle disease that affects both the muscles as well as the skin. DM can affect people of all races, sex and age. Patients with dermatomyositis usually present with complaints of tiredness and loss of energy. The skin changes occur before the onset of muscle disease in most patients. The earliest signs of skin manifestations may begin with a red to bluish-purple rash most commonly in the sun exposed areas (face, neck, shoulders, upper chest and back). The eyelids may get the typical purple rash known as the heliotrope rash. Early clinicians thought that this violaceous rash around the eyes reminded them of the color of a heliotrope flower, and thus referred to this as the ‘heliotrope sign’. The knuckles may have purple spots known as ‘Gottron’s papules’.(http://www.aocd.org/?page=Dermatomyositis)
