Which part of the neuron can conduct an action potential?
The method through which neurons interact with neighboring neurons usually consists of several axon terminals connecting through synapses to the dendrites on other neurons. If a stimulus creates a strong enough input signal in a nerve cell, the neuron sends an action potential and transmits this signal along its axon.
Why does an action potential travel in one direction down an axon?
Action potentials travel in only one direction down an axon because sodium channels in the neuron are refractory. Influx of Na+ ions into the neuron can lead to membrane depolarization above the threshold potential; this event triggers the creation of an action potential.
What are the 4 steps of an action potential?
An action potential is caused by either threshold or suprathreshold stimuli upon a neuron. It consists of four phases; hypopolarization, depolarization, overshoot, and repolarization. An action potential propagates along the cell membrane of an axon until it reaches the terminal button.
What occurs during hyperpolarization of a neuron membrane?
What occurs during hyperpolarization of a neuron membrane? The neuron fires at its maximum voltage if a stimulus depolarizes the neuron to threshold.
