Skeletal muscle
Skeletal muscle fibers secrete an external lamina that lies immediately adjacent to the sarcolemma (cell membrane). Outside the basal lamina is a layer of reticular fibers, produced by fibroblasts, which form the endomysium. Some consider the basal lamina to be a component of the endomysium. 15,000x
