Answer: B) The end of one neurons releases neurotransmitters that influence the membrane potential of the next neuron.
Explanation:
Neurons communicate with each other, when the neuron presynaptic relays stimulus, the membrane potential reach at the end nobs of axon and then it gives signal to neurosecretory vesicles at the end of neurons and then, vesicles are filled with neurotransmitters. As, neurotransmitters are the small molecules which contains different chemical composition like dopamine, glycine and acetylcholine. And then, vesicles released neurotransmitters in synapse. Receptors send signal to the neurons with the interaction of neurotransmitter to generate membrane.

Produced by the adrenal glands, it s main function is to trigger a quick response to potenital threats, seen an increased blood pressure to muscles, heart rate, pupils dilatation and increased metabolyizing of suger.
The incorrect levels of epinephrine will characterize a person suffering an anxiety disorder. If a situation requieres a stress response, epinephrine will help a living organism like mammals to answer quickly and surive.
