What is the correct order of events in an action potential?

An action potential has three phases: depolarization, overshoot, repolarization. There are two more states of the membrane potential related to the action potential. The first one is hypopolarization which precedes the depolarization, while the second one is hyperpolarization, which follows the repolarization.

What are the 4 steps of an action potential?

An action potential can be further broken down into its separate stages: depolarization, repolarization, hyperpolarization, and the refractory period.

What are the 5 steps of an action potential in order?

The action potential can be divided into five phases: the resting potential, threshold, the rising phase, the falling phase, and the recovery phase.

What happens in phase 4 of the action potential cycle?

In these cells, phase 4 is also known as the pacemaker potential. During this phase, the membrane potential slowly becomes more positive, until it reaches a set value (around -40 mV; known as the threshold potential) or until it is depolarized by another action potential, coming from a neighboring cell.

What is the first event of an action potential quizlet?

The first step with regards to the generation of an action potential is the opening of voltage-gated potassium channels at the axon hillock.

What is the first step during an action potential?

Depolarization. During the depolarization phase, the membrane potential increases from - 70 mV to + 40 mV due to the presence of a stimulus, and this is the first phase of an action potential.

What is the correct sequence of events involved in an action potential start with the number of the first step and go step by step through the events?

Answer and Explanation: The correct answer is c. 2, 1, 4, 3. The potential along the cell membrane is the difference in the cell's electric gradient between the inside and outside of the nerve cell membrane.

What are the 5 steps of an action potential in order?

The action potential can be divided into five phases: the resting potential, threshold, the rising phase, the falling phase, and the recovery phase.

What is the first step in an action potential?

Depolarization. During the depolarization phase, the membrane potential increases from - 70 mV to + 40 mV due to the presence of a stimulus, and this is the first phase of an action potential.

What is the sequence of structures an action potential must pass through in order to excite skeletal muscle contraction?

Answer and Explanation: c. Axon of neuron, sarcolemma, T tubules represents the sequence muscle action potentials must go through to excite a muscle cell.

What is the first event of an action potential quizlet?

The first step with regards to the generation of an action potential is the opening of voltage-gated potassium channels at the axon hillock.
