What is the fibrous connective tissue that surrounds and separates the levels within the skeletal muscle and provides resistance to forces in different directions?

• A. Fascia
• B. Endomysium
• C. Perimysium
• D. Epimysium

Answer: (A)

Inside skeletal muscle, connective tissue forms layers that organize fibers into units and help transmit force. The perimysium is the fibrous layer that wraps around bundles of muscle fibers to form fascicles. This layer both separates the levels within the muscle (fibers grouped into fascicles) and provides resistance to forces coming from different directions because its collagen fibers are arranged in a multidirectional network. That arrangement helps distribute tensile loads across the fascicles and contributes to stableness when the muscle stretches or contracts. In contrast, the tissue that surrounds the entire muscle and helps separate muscles from one another is fascia, a broader layer outside the muscle itself. The endomysium surrounds individual muscle fibers, and the epimysium encases the whole muscle. The perimysium specifically handles the organization and mechanical stability of the internal muscle structure by wrapping fascicles and resisting multidirectional stress.
