Synapse

Vedclass · Answer

(A) The unidirectional transmission of nerve impulses is primarily due to the presence of a $Synapse$. At a chemical synapse,neurotransmitters are released only from the presynaptic membrane of the axon terminal into the synaptic cleft. These neurotransmitters then bind to specific receptors located only on the postsynaptic membrane of the dendrite or cell body. Because receptors are absent on the presynaptic side and neurotransmitter vesicles are absent on the postsynaptic side,the impulse can only travel in one direction.
