Which layer surrounds a bundle of muscle fibers (fascicle)?

Explanation:
Bundles of muscle fibers, or fascicles, are wrapped by a connective tissue layer called the perimysium. This layer sits around each fascicle, grouping multiple fibers together and providing pathways for nerves and blood vessels to reach the fibers inside. The endomysium surrounds each individual muscle fiber, while the epimysium encases the entire muscle. Blood vessels run through both the perimysium and epimysium to supply the muscle, but the defining layer that surrounds a fascicle is the perimysium.
