skeletal muscle (voluntary muscle)

A collection of striated muscle fibers connected at either or both extremities within a bony framework of the body. Histology: - histologically, the muscle consists of elongated, multinucleated, transversely striated muscle fibers together with connective tissues, blood vessels & nerves - individual muscle fibers are surrounded by fine reticular & collagen fibers (endomysium). - bundles or fascicles of muscle fibers are surrounded by irregular connective tissue (perimysium) - the entire muscle is surrounded, except at the tendon junction, by a dense connective tissue (epimysium). Physiology: - muscle fibers regenerate by recruitment of muscle stem cells satellite cells Pathology: - see muscular disease - see age-associated changes in skeletal muscle
