What is the function and an example of a muscle(tissue)?

The function of muscular system is to move our body, so if I had no muscle in my fingers I wouldn't have been able to type this answer. 

For muscle tissue there are three types of tissues: skeletal, cardiac, and smooth muscle. They provide posture and body support, locomotion, and heat production. 

Hope you understand what I said
