Skeletal muscles are a type of muscle tissue that allows voluntary movements in the body. Each skeletal muscle is surrounded by a sheath of connective tissue called the epimysium. Parts of the epimysium protrude inwards to group the muscle fibers or cells into sections called fascicles. Each fascicle is enclosed by another layer of dense connective tissue called the perimysium. Within a fascicle, each muscle fiber is also enveloped by a sheath of connective tissue called an endomysium. All these three sheaths of connective tissues are continuous with each other. Besides supporting and protecting the muscle cells during muscle contraction, they also provide a passageway for the nerves and blood vessels, crucial for transmitting nerve impulses and supplying oxygen and nutrients. They may also extend beyond the muscles to form a rope-like tendon or as a sheath-like aponeurosis, which serves as attachments to the bones or other muscles. On contraction, the muscle fibers pull the continuous sheaths, generating a force that propagates to these muscle attachments and ultimately moves the bone.
