Question

Quizplus · Accepted Answer

The task of passing a message from one neuron to another is carried out by neurotransmitters. These are chemical messengers that are released from the axon of one neuron and travel across the synapse to the dendrite or cell body of another neuron, where they bind to specific receptor sites and transmit the message. The myelin sheath is a fatty coating that surrounds some axons and speeds up the transmission of signals, but it does not directly pass the message from one neuron to another. Glia cells play supportive roles in the nervous system, such as providing nutrients and insulation to neurons, but they do not transmit messages. The action potential is an electrical signal that travels along the axon of a neuron, but it also does not directly pass the message from one neuron to another.
