Question

Quizplus · Accepted Answer

A synapse is a junction between a sending neuron and a receiving neuron, where information is transmitted via chemical or electrical signals. It is not a chemical messenger that triggers muscle contractions (choice A), nor is it an automatic response to sensory input (choice B). A neural cable containing many axons is known as a nerve (choice D), not a synapse.
