B
sarcolemma
C
myofibril
D
epimysium
Verified step by step guidance
1
Understand the structure of skeletal muscle: Skeletal muscle is organized into layers of connective tissue. These layers include the epimysium, perimysium, and endomysium, each serving a specific function.
Define the epimysium: The epimysium is the outermost layer of connective tissue that surrounds the entire muscle. It provides structural support and protection for the muscle as a whole.
Identify the role of the epimysium: The epimysium contains nerves and blood vessels that supply the muscle. These structures are essential for delivering oxygen, nutrients, and removing waste products, as well as transmitting signals for muscle contraction.
Differentiate the other options: The endomysium surrounds individual muscle fibers, the sarcolemma is the plasma membrane of a muscle cell, and the myofibril is a structural unit within the muscle fiber responsible for contraction. None of these contain nerves and blood vessels.
Conclude that the correct answer is the epimysium, as it is the connective tissue layer that houses nerves and blood vessels within the muscle.
