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 a neuromuscular junction is electrical, as action potentials travel down the neuron. When the action potential reaches the axon terminal, it triggers the release of neurotransmitters (a chemical signal) across the synaptic cleft to the muscle sarcolemma, making the stimulus from axon terminal to muscle sarcolemma chemical.
