Question

Quizplus · Accepted Answer

Neurons communicate with each other through the release of chemicals known as neurotransmitters across the synapse, a small gap between neurons. These neurotransmitters are released from the axon terminal of one neuron and bind to receptors on the dendrites of another neuron, facilitating communication.
