Question

Quizplus · Accepted Answer

When a neural impulse reaches the end of an axon, it causes tiny oval sacs at the end of the axon to release chemicals called neurotransmitters. This is how neurons communicate with each other and send messages throughout the body. Hormones are released by glands and affect organs and tissues in the body, but do not play a direct role in neural communication at the synapse. Antioxidants and electrolytes are not directly involved in the release of neurotransmitters.
