The stimulus from motor neuron to neuromuscular junction is________ _, and the stimulus from axon terminal to muscle sarcolemma is________ .

Question

Quizplus · Accepted Answer

The stimulus from a motor neuron to the neuromuscular junction is electrical, as action potentials travel down the neuron. At the axon terminal, the electrical signal triggers the release of neurotransmitters, which then cross the synaptic cleft chemically to stimulate the muscle sarcolemma.

The Stimulus from Motor Neuron to Neuromuscular Junction Is________ _
