An individual skeletal muscle cell
A
muscle fiber
B
fascicle
C
sarcolemma
D
aponeurosis
E
agonist
Explanation: 

Detailed explanation-1: -Each skeletal muscle consists of thousands of muscle fibers wrapped together by connective tissue sheaths. The individual bundles of muscle fibers in a skeletal muscle are known as fasciculi. The outermost connective tissue sheath surrounding the entire muscle is known as epimysium.

Detailed explanation-2: -Skeletal muscle fibers are broadly classified as “slow-twitch” (type 1) and “fast-twitch” (type 2).

Detailed explanation-3: -Skeletal muscle fibers are innervated by motor neurons whose cell bodies are located in the ventral horn of the spinal cord. The terminal region of the axon gives rise to very fine processes that run along skeletal muscle cells.
