Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

The following steps refer to various stages in transmission at a chemical synapse Neurotransmitter binds with receptors associated with the postsynaptic membrane.Calcium ions rush into the neuron’s cytoplasmAn action potential depolarizes the membrane of the axon terminalThe ligand gated ion channels openThe synaptic vesicles release neurotransmitter into the synaptic cleftWhich sequence of events is correct?

A	3
B	5
C	2
D	4

Explanation:

Detailed explanation-1: -Synthesis of the neurotransmitter in the presynaptic nerve terminal. Storage of the neurotransmitter in secretory vesicles. Regulated release of neurotransmitter in the synaptic space between the pre-and post-synaptic neurons. More items

Detailed explanation-2: -Neuronal impulse travels down the presynaptic axon to axon bulb. Synaptic vesicles fuse with the axon bulb plasma membrane, releasing neurotransmitters. Neurotransmitter is released into the synaptic cleft. Neurotransmitter bind to receptors on the postsynaptic neuron. More items
