Question

Quizplus · Accepted Answer

The knoblike structures branching out from an axon are called terminal buttons. Terminal buttons contain and release neurotransmitters into the synapse, allowing communication with the next neuron or muscle cell. Hormones are chemical messengers secreted by endocrine glands, neurotransmitters are chemical messengers used in neural communication, and synapses are the tiny gaps between neurons where chemical communication occurs.
