Verified step by step guidance

Understand the hierarchical structure of a muscle: Muscles are composed of bundles of muscle fibers, which are further organized into smaller units called fascicles.

Learn the role of connective tissue layers in muscle anatomy: The muscle is surrounded by three layers of connective tissue—epimysium, perimysium, and endomysium. Each layer has a specific function and surrounds a specific structure.

Focus on the perimysium: The perimysium is the connective tissue layer that surrounds and separates fascicles, which are bundles of muscle fibers. This layer provides support and allows blood vessels and nerves to reach the muscle fibers within the fascicles.

Differentiate the other connective tissue layers: The epimysium surrounds the entire muscle, while the endomysium surrounds individual muscle fibers. Myofibrils, which are the contractile units within muscle fibers, are not directly surrounded by any of these connective tissue layers.

Conclude that the perimysium specifically surrounds fascicles, making it the correct answer to the question.
