What is skeletal muscle?

Skeletal striated muscle tissue is formed by bundles of very long, multinucleated cylindrical fibers known as skeletal striated muscle fibers. These bundles are surrounded by the epimysium, an outer membrane of dense connective tissue. Septa of very thin connective tissue, called perimysium, depart from these membranes, through which blood vessels enter the muscles. They are muscles of voluntary movement.

Myosin is made up of two subunits, light meromyosin and heavy meromyosin. The light meromyosin corresponds to the largest portion of the rod, while the heavy meromyosin is composed of the smallest part of the rod next to the globular projection.

The sarcolemma consists of a cell membrane, called the plasma membrane, and a lining of a thin layer of polysaccharide material, with many thin collagen fibrils.
