Muscle contraction can only occur through the generation of neural activation. Which of the following is not a part of this process?
a. electrical impulses travel along the neuron
b. muscle fibers are wrapped together into bundles
c. acetylcholine stimulates muscle fibers
d. release of neurotransmitters occurs
Answer: b. muscle fibers are wrapped together into bundles
Muscle fibers are being wrapped together does not generate neural activation, it is simply a description of the anatomy of the muscle fiber. Muscle contraction occurs after the electrical impulse travels along the neuron, neurotransmitters are released across the synapse to muscle fiber, and then acetylcholine produces the contraction of the muscle.
