1. The smallest muscle in the human body is the stapedius in the middle ear. It is only about 1.5 centimeters long.

3. The strongest muscle in the human body is the masseter muscle, located in the jaw and responsible for chewing.
4. Muscles make up about 40% of a person’s total body weight.

7. When we shiver, our muscles produce heat to keep our bodies warm.
