Neurotransmitters are released by axon terminals and not by dendrites.

Vedclass · Answer

(D) The transmission of nerve impulses across a synapse is unidirectional because neurotransmitters are stored in synaptic vesicles located only at the axon terminals (presynaptic membrane). When an action potential reaches the axon terminal,these vesicles fuse with the presynaptic membrane and release neurotransmitters into the synaptic cleft. The dendrites (postsynaptic membrane) contain specific receptors for these neurotransmitters,but they do not contain synaptic vesicles to release them. Therefore,the impulse can only travel from the axon terminal of one neuron to the dendrite of the next neuron,ensuring a one-way flow of information.
