Neurotransmitters are released from axon terminals via _______. A. osmosis B. active transport C. diffusion D. exocytosis
Nutka1998 [239]

The correct option is D

Neurotransmitters are released from axon terminals via exocytosis.

A neurotransmitter is stored inside synaptic vesicles which is a small sac-like structure. It is released into the synaptic cleft from axon terminals when a cell membrane fuses with vesicles. This process is termed exocytosis with the capability to release neurotransmitters in less than a millisecond.

In neurons of the nervous system, synaptic vesicle exocytosis occurs. Nerve cells communicate by electrical or chemical signals called neurotransmitters which are passed from one neuron to the next one. This transmission of neurotransmitters occurs by exocytosis.

The fundamental biological events of neurotransmission are dependent on neuronal communication and brain function including exocytosis of presynaptic vesicles which is for the release of neurotransmitters and the subsequent endocytosis.
