Verified step by step guidance

Understand the structure of a muscle: A muscle is composed of bundles of muscle fibers, and these fibers are surrounded by connective tissue layers. These layers include the epimysium, perimysium, and endomysium.
Learn the function of each connective tissue layer: The epimysium surrounds the entire muscle, the perimysium surrounds bundles of muscle fibers (fascicles), and the endomysium surrounds individual muscle fibers.
Recognize the location of capillaries: Capillaries are small blood vessels that provide oxygen and nutrients to muscle fibers. They are located within the connective tissue layer that directly surrounds individual muscle fibers.
Match the correct connective tissue layer: Since capillaries are located around individual muscle fibers, they are found within the endomysium, which is the innermost connective tissue layer.
Confirm the correct answer: Based on the anatomical structure and function, the capillaries that wrap around each muscle fiber are located within the endomysium.
