An action potential is something that only occurs at synapses. Afferent pathways send sensory information to the CNS for processing. When they are at rest, neurons are more positively charged inside than outside the cell. Action potentials originate at the axon terminal and move towards the dendrites. An action potential travels down the length of the neuron with the help of voltage-gated calcium channels. Neurons can only have one action potential and must be recycled by glia once they have depolarized. At axon terminals, calcium influx stimulates vesicle release. Ligand-gated ion channels open in response to a molecule binding to them. FALSE 4. For each FALSE statement in # 3, explain why it is incorrect.
