The place where an impulse is tansmitted from a motor neuron to a skeletal muscle is called A. Intercalated disc
B. Myofibril
C. Origin point
D. Neuromuscular junction

Another specialization of the skeletal muscle is the site where a motor neuron's terminal meets the muscle fiber—called the neuromuscular junction (NMJ). This is where the muscle fiber first responds to signaling by the motor neuron.

D. Neuromuscular Junction

i think that is new experiments yield untrustworthy data and should be carefully considered, because you don't know what will happen with the experiments.
