The primary functions of the skeletal muscle take place via its intrinsic excitation-contraction coupling process. As the muscle is attached to the bone tendons, the contraction of the muscle leads to movement of that bone that allows for the performance of specific movements. The skeletal muscle also provides structural support ...
The skeletal muscle also provides structural support and helps in maintaining the posture of the body. The skeletal muscle also acts as a storage source for amino acids that can be used by different organs of the body for synthesizing the organ-specific proteins.[12] .
The two most significant myofilaments are actin and myosin filaments which are arranged distinctively to form various bands on the skeletal muscle.
There is a unique T-tubule system in place for conduction of neuronal action potential to the interior of the muscle cell via invaginations of the sarcolemma to enhance coordination and uniform muscle contraction. [25] Clinical Significance. Skeletal muscles enable humans to move and perform daily activities.
The outermost sheath of connective tissue covering each muscle is called as epimysium. Each muscle is made up of groups of muscle fibers called fascicles which are surrounded by a connective tissue layer called perimysium.
After birth, the satellite cells act as stem cells and are responsible for the further growth and development of skeletal muscles.
These regulatory factors include the Wnt, Shh and BMP4 proteins.
