Question

Quizplus · Accepted Answer

Neurotransmitters are the chemicals that facilitate movement of impulses at synapses. They are released from the axon terminals of one neuron and transmit signals to the dendrites or cell body of another neuron or an effector cell, like a muscle or gland. Opiates, sedatives, hypnotics, and analgesics are all types of drugs that affect the nervous system in various ways, but do not necessarily facilitate movement of impulses at synapses.
