In synaptic transmission, the action potential stimulates the release of:
A)potassium ions by the glial cells.
B)neurotransmitters by the synaptic vesicles.
C)myelin by the glial cells.
D)sodium ions by the dendrites.

Question

Quizplus · Accepted Answer

The action potential stimulates the release of neurotransmitters from the synaptic vesicles into the synaptic cleft. This is the key step in communication between neurons. Potassium ions are not released by glial cells in synaptic transmission. Myelin is not released either. Sodium ions are involved in the action potential itself, but are not directly released by dendrites in synaptic transmission.
