Understanding Action Potential Generation

Easy Unit 2: Biological Bases Neural Communication

Neural communication involves the transmission of signals between neurons. This process begins when a neuron receives a signal from its surroundings, leading to a change in its electrical state. One essential step in this communication process is the generation of an action potential.

Which of the following accurately describes the process of action potential generation?

An action potential is generated when a neuron is stimulated by another neuron, leading to a decrease in membrane potential.

An action potential occurs when sodium ions rush into the neuron, causing a rapid depolarization.

An action potential is created only when a neurotransmitter binds to a receptor on the post-synaptic neuron.

The generation of an action potential is inhibited when potassium ions exit the neuron.

An action potential is similar to a graded potential in that both can vary in strength.
