Muscular system

Muscles have the ability to contract and expand. Muscles along with skeletal system help in movement of body parts and locomotion.

There are 2 types of muscles:
Voluntary muscles - Muscles which we control knowingly. e.g. hand, leg or mouth muscles.
Involuntary muscles - Muscles which we don't control directly. e.g muscles of the heart and digestive system.

Cardiac muscles are found on the walls of the heart. Cardiac muscles are under involuntary control.

Smooth muscles are found in internal organs like blood vessels, organs of digestive and respiratory systems. These are called involuntary because we do not control the movement of these muscles. We can control only voluntary muscles like muscles of our hand or mouth etc.

Eye muscles are busiest muscles in our body.

The Gluteus Maximus is the biggest muscle in the human body. This muscle is located at the back of the hips and is commonly known as buttocks.
