Question
Chapter 12.2, Problem 4WDYL
Summary Introduction
To explain:
The function of neuron structures: dendrites, axon, synaptic vesicles and neurofibrils.
Concept introduction:
A neuron is a basic functional unit of the nervous system and is the specialized cells of the nervous system that makes a complex network for the transmission of messages. A neuron is made up of a cell body, nerve fibers, dendrites, Schwann cell, and an axon

Which of the following is the role of axonal Calcium (Ca2+) channels in neuronal communication at the synapse?
a) they inhibit the action potential causing it to stop
b) Calcium channels have no role in this process
c) by allowing calcium to exit the cell, they promote the propagation of action potential across the synapse by creating depolarization
d) by blocking calcium entrance, they mediate the contraction of presynaptic axon to facilitate movement
e) when they open, calcium enters the presynaptic terminal, promoting fusion of neurotransmitter vesicles with presynaptic membrane, and release of neurotransmitters to the synaptic cleft
