C)The degree of sustained depolarization at the axon hillock determines the frequency of action potentials.
D)The number of postsynaptic cells that a presynaptic cell is communicating with determines the frequency of action potentials.
E)The length of the presynaptic cell axon determines the frequency of action potentials.

Question

Quizplus · Accepted Answer

The degree of sustained depolarization at the axon hillock determines the frequency of action potentials. When the membrane potential at the axon hillock of a neuron reaches the threshold level, voltage-gated ion channels open and allow an influx of sodium ions, causing depolarization and the generation of an action potential. The frequency of action potential generation is determined by the degree of sustained depolarization at the axon hillock, which is influenced by the strength and duration of the synaptic inputs received by the neuron.
