What term describes a bundle of muscle fibers surrounded by perimysium?

• A. Endomysium
• B. Epimysium
• C. Muscle fascicles
• D. Muscle fibers

Answer: (C)

A muscle fascicle is a bundle of skeletal muscle fibers encased by perimysium. The endomysium surrounds each individual fiber, while the epimysium wraps the entire muscle. So, when you see a bundle of fibers together with perimysium, that unit is a fascicle. Fascicles group to form the whole muscle, with the epimysium enclosing them all. This arrangement helps organize force transmission and provides pathways for nerves and blood vessels to reach the fibers.
