A Correct answer
Explanation

Fatigue is a subjective feeling of tiredness which is distinct from weakness and has a gradual onset. Neuromuscular fatigue involves the depletion of acetylcholine which is a neurotransmitter released to stimulate skeletal muscles and the parasympathetic nervous system. Muscle contraction is then ended by the release of aceltylchlineterese from the muscle sarcomere.
