Skeletal muscle tissue is responsible for all conscious body movements, including limb movement, facial expressions, eye movements, and swallowing. As a consequence of cellular metabolism, skeletal muscle contractions also produce the majority of the bodyās heat.
Skeletal muscle cells display a striped, or striated, pattern of light and dark regions when examined under a microscope. The orderly organization of actin and myosin proteins within cells into structures known as myofibrils causes these stripes.
