Structure of Muscle
Muscle is one of the four tissues in the body and plays a key role in the locomotion of higher animals. Besides locomotion, muscles are also associated with digestion, respiration, circulation, excretion and reproduction. There are three main types of muscles: smooth or unstriated muscle, skeletal or striated muscle, and cardiac muscle. This article explains the structure and characteristics of muscles, with particular focus on skeletal muscle and its role in movement.
