WebSkeletal muscles consist of flexible muscle fibers that range from less than half an inch to just over three inches in diameter. These fibers usually span the length of the muscle. … WebMuscle fibers are grouped into bundles called fascicles. Each fascicle is surrounded by perimysium. An entire muscle is surrounded by epimysium ; Each skeletal muscle fiber is long (up to 30cm; 12 inches) and striated in appearance. The striations in skeletal muscle are a result of many repeating units called sarcomeres, which are the ...

Within this is a layer termed the epimysium which splits inwards into the muscle as the perimysium dividing muscle fibers into groups termed fascicle. Each fascicle is surrounded by another layer of connective tissue termed the endomysium.
