Musculoskeletal system of the body is one of those important ones, through which every body movement is made possible.All 206 bones in the human body are linked with the muscles in some way or the other which enables the bones to move and perform actions..

Some muscles in the human body our involuntary that is they are continously working without the instructions from the brain, like the cardiac muscles in the heart, because of which the heart is continously pumping.Other examples of involuntary muscles are bladder muscles, and eye muscles for blinking.

Ligaments and cartilage are used to draw bones together and provide a means of keeping the bones and joints functioning properly. Without the cartilage the bones would rub against each other causing significant wearing of the bone.
