Final answer:
Skeletal muscle is indeed composed of multiple layers surrounded by connective tissue. The layers are the epimysium, perimysium, and endomysium, which enclose and support the muscle fibers and allow the entry of blood vessels and nerves.
Step-by-step explanation:
The statement about skeletal muscle being comprised of multiple layers surrounded by connective tissue is true. Skeletal muscles are complex organs made up of skeletal muscle fibers, blood vessels, nerve fibers, and an extensive network of connective tissue. There are three distinct layers of connective tissue, commonly referred to as the mysia, that provide structure and integrity to these muscles.
The outermost layer is the epimysium, which is a dense layer of connective tissue that envelopes the entire muscle. It allows the muscle to move powerfully without losing its shape. The middle layer, or perimysium, groups muscle fibers into bundles called fascicles. Each individual muscle fiber within a fascicle is further encased by an inner layer of connective tissue known as the endomysium. This detailed hierarchical structure not only provides protection and support for muscle fibers but also provides a pathway for blood vessels and nerves to reach each muscle fiber, ensuring their functionality.
Connective tissues play a crucial role in muscle physiology, allowing skeletal muscles to maintain posture, stabilize bones and joints, and produce movement efficiently. Their configuration into bundles within bundles facilitates coordinated muscular contraction and allows for varied movements and forces to be applied by the muscles.
