Skeletal muscle

The muscles are classified by gross appearance and location of the cells. The three types of muscles are striated (skeletal), cardiac, and smooth (nonstriated). Skeletal muscle (SM) plays a major role in body movements. They are called a 'major arm of the nervous system' in order to move. The interactions of various muscles produce well-coordinated movements that are needed for daily functional activities, routines, and sports. To understand the physiology of movement, it is essential to understand basic structure and function of SMs. The force producing capability of SM is regulated by a number of simultaneously occurring processes that provide real-time fine-tuning of contractility
