Voltage -gated calcium channels in the axon terminal open in response to which of the following?
A) summation of graded potentials at the axon hillock
B) paracrines released from the post -synaptic cell
C) initiation of an action potential in the axon hillock
D) neurotransmitter binding to receptor
E) arrival of an action potential at the axon terminal

Question

Quizplus · Accepted Answer

Voltage-gated calcium channels in the axon terminal open in response to the arrival of an action potential at the axon terminal. This influx of calcium ions triggers the release of neurotransmitters into the synaptic cleft.
