MT30-Histology Art AB 3 years, 7 months ago Skeletal muscle accounts for approximately 40% of total body mass and is the most common and extensively distributed muscle tissue. It is found in the eyes, throat, diaphragm, and anus and is responsible for the development of all skeletal muscles such as the biceps brachii and gluteus maximus.-
Skeletal muscle tissue cells are voluntary, striated, non-branched, and multinucleated. Skeletal muscle tissue is the only type of muscle tissue that is directly controlled by the cerebral cortex of the brain, giving it the label of voluntary muscle-
All conscious bodily motions, including limb movement, face expressions, eye movements, and swallowing, are controlled by skeletal muscle tissue. Skeletal muscle contractions provide most of the body’s heat because of cellular metabolism.

Skeletal muscle cells differ from other muscle tissues because of their structure. Skeletal muscle cells are generated throughout fetal development by the union of numerous smaller cells, resulting in long, straight muscle fibers with many nuclei

When studied under a microscope, skeletal muscle cells exhibit a striped, or striated, pattern of bright and dark areas. These stripes are caused by the orderly arrangement of actin and myosin proteins within cells into structures known as myofibrils. Myofibrils are responsible for the skeletal muscles’ amazing power and ability to pull and push the body with great force
