Gross inspection of a skeletal muscle reveals collections of muscle fascicles surrounded by a layer connective tissue termed the epimysium. Each muscle fascicle represents a group of muscle fibers bound together by a layer of connective tissue termed the perimysium.
Microscopic Anatomy
The plasma membrane of the skeletal muscle fiber is called a sarcolemma. The muscle fiber contains long cylindrical structures, the myofibrils. The myofibrils almost entirely fill the cell and push the nuclei to the outer edges of the cell under the sarcolemma.
