The first human muscle diagram above shows you the overview of the human muscular system. The main function of the muscular system is movement. Muscles are the only tissue in the body that has the ability to contract and therefore move the other parts of the body. These muscles also often contract to hold the body still or in a particular position rather than to cause movement. The following muscle diagram shows the posterior and anterior view of the muscle anatomy.

The cardiac and visceral muscles are primarily responsible for transporting substances like blood or food from one part of the body to another. Each muscle also has its own blood supply, arteries and veins, alongside its own nerve connections. The human body consists of around 640+ skeletal muscles.
