Answer:
Transmission of nerve impulse across a synapse :
(1) This transmission takes place with the help of neurotransmitters.
(2) Once the neurotransmitters bind to the receptors of the post-synaptic cell, the action is either excitatory or inhibitory depending on the type of neurotransmitter.
(3) The enzyme like acetyl cholinesterase destroys the neurotransmitter after the transmission and the synapse is ready to receive a new impulse.
