What occurs sequentially when the nerve impulse is transmitted from the synapse of one neuron to the postsynaptic neuron?
|
|
The nerve impulse is transmitted next to the axon of the presynaptic neuron
|
|
|
The synaptic vesicles release neurotransmitters into the synaptic cleft by exocytosis
|
|
|
The nerve impulse is transmitted to the postsynaptic neuron by a direct connection between the two
|
|
|
The nerve impulse is transmitted to the axon of the postsynaptic neuron
|
Explanation:
Detailed explanation-1: -(i) Opening of specific ion channels allows the entry of ions, a new action potential is generated in the post-synaptic neuron. (ii) Neurotransmitter binds to the receptor on post synaptic membrane. (iii) Synaptic vesicle fuses with pre-synaptic membrane, neurotransmitter release into synaptic cleft.
