|
|
When a neuron is activated by a stimulus, it becomes positively charged causing an action potential
|
|
|
When a neuron is in a resting state it is positively charged
|
|
|
When a neuron is in a resting state it is negatively charged
|
|
|
The action potential creates an electrical signal that travels along the axon

Detailed explanation-1: -Resting Membrane Potential A neuron is at rest when it is not sending an an electrical signal. During this time, the inside of the neuron is negative relative to the outside.
Detailed explanation-2: -Answer and Explanation: The correct answer is option A. During the resting state of a neuron, the inside of the cell has a negative charge, as compared to the positive charge of the extracellular environment.
Detailed explanation-3: -What happens when a neuron is at rest? In the resting state, there is no signal passing through the neuron. However, even in this state, the neuron is electrically active. Because of how ions are moving across the cell membrane, the inside of the neuron is more negative than the fluid that surrounds it.
Detailed explanation-4: -At rest, a typical neuron has a resting potential (potential across the membrane) of −60 to −70 millivolts. This means that the interior of the cell is negatively charged relative to the outside.
