What are muscles?

We humans have over 150 muscles.

Muscles are body tissues or organs (human and animal) known for their ability to contract and stretch.

There are two types:

Striated muscles which cover the skeletal structure.
Smooth muscles which are in the skin, blood vessels, digestive tract, respiratory tract and urogenital apparatus.
