Skeletal muscle is made up of individual muscle cells or myocytes, known as muscle fibers. They are formed from the fusion of developmental myoblasts (a type of embryonic progenitor cell that gives rise to a muscle cell) in a process known as myogenesis.Muscle fibres are cylindrical, and multinucleated.keletal muscle is a form of striated muscle tissue which is under the voluntary control of the somatic nervous system. It is one of three major muscle types, the others being cardiac muscle and smooth muscle.
Muscle Contraction. Muscle fibers contract in response to nerve stimuli from your central nervous system. This is an active process that involves the release of calcium at the cellular level of the muscle fiber, and causes a ratcheting effect that results in the shortening, or contracting, of individual muscle fibers.HARE SHARE TWEET EMAIL. Muscle contraction and relaxation occurs in your body multiple times during the course of a day, especially if you are active. Muscles have fibers, and the fibers are grouped into fascicles, or bundles, which form individual skeletal muscles.
