What else can I help you with?
When the electrical potential in a cell is in action versus a resting state the electrical charge reversal?
When a cell is in action, the electrical potential becomes more positive compared to the resting state. This is due to an influx of positively charged ions such as sodium. During the resting state, the electrical potential is negative, maintained by the concentration gradient of ions across the cell membrane.
What is a resting motor neuron expected to do?
exhibit a resting potential that is more negative than the "threshold" potential
What is the interval called during which a neuron is dormant after an action potential has been completed?
Resting potential
A resting motor neuron is expected to?
exhibit a resting potential that is more negative than the "threshold" potential.
During an action potential hyperpolarization beyond more negative to the resting membrane potential is primarily due to?
Potential hyperpolarization are more negative to the resting membrane potential because of voltage. This is taught in biology.
What is the reversal of the resting potential owing to an influx of sodium ions called?
The reversal of the resting potential owing to an influx of sodium ions is called depolarization. This occurs when the membrane potential becomes less negative, bringing it closer to the threshold for action potential initiation.

What restores the resting potential after the action potential passes through an axon?
The resting potential is restored after the action potential passes through an axon by the sodium-potassium pump, which actively transports sodium ions out of the cell and potassium ions into the cell. This process helps maintain the balance of ions inside and outside the cell, returning the membrane potential to its resting state.
What restores and puts the cell membrane to resting conditions after an action potential?
Calcium
The sudden reversal of electrical charge across the neuron membrane is called?
Action potential is a short-lasting event in which the electrical membrane potential of a cell rapidly rises and falls, following a consistent trajectory. Action potentials occur in several types of animal cells, which include neurons, muscle cells, and endocrine cells, as well as in some plant cells. In neurons, they play a central role in cell-to-cell communication.
Action potential will be propagated only after a sufficiently large resting membrane potential has been achieved in the direction of?
depolarization
Are neurotransmitters that depress the resting potential called excitatory?
No, neurotransmitters that depress the resting potential are called inhibitory neurotransmitters. Excitatory neurotransmitters have the opposite effect, causing depolarization and increasing the likelihood of an action potential.
Arrange these action potential events in their proper sequence?
The correct sequence of action potential events is: 1. Resting membrane potential, 2. Depolarization, 3. Repolarization, 4. Hyperpolarization.
