In neuron functioning,the role of the synaptic vesicle is to
A) accumulate sodium ions inside the semipermeable membrane.
B) create new myelin sheaths on demand from the nervous system.
C) send the electrochemical signal to the axon hillock.
D) store neurotransmitters in the synaptic knob.

Question

Quizplus · Accepted Answer

The role of the synaptic vesicle is to store neurotransmitters in the synaptic knob until they are released into the synaptic cleft to initiate a response in the next neuron. Accumulation of sodium ions inside the semipermeable membrane occurs in the action potential, while myelin sheaths are produced by oligodendrocytes or Schwann cells, not synaptic vesicles. The axon hillock receives synaptic input from dendrites and decides whether to initiate an action potential, but it is not the role of the synaptic vesicle.
