The difference in charge across the membrane is called the membrane potential. It is measured in Milivolts.

At resting potential, the charge of the outside of the neuron is positive and the inside is negative. Once a stimulus changes the membrane potential, the neuron conducts an impulse called a(n) action potential.

This causes the charge outside the cell to temporarily become negative and the inside to temporarily become positive.

When the action potential arrives at the axon terminal it reaches a junction called the synaptic cleft.

Because the nerve impulse cannot cross the synaptic cleft, neurotransmitters are released.

Explanation:

The cell has a membrane that acts as a barrier between the outside and the inside of the cell, allowing the passage of some ions and retaining others. By doing this, there is a difference in charges between the inside and outside that is called the membrane potential, thanks to this difference in charge that the membrane creates the cell can communicate with other cells generating an action potential, which is a modification in the cell charge due to the flow of positive ions to the inside and the exit of negative ions to the outside. This is a temporary modification that ends when the action potential arrives at the presynaptic terminal releasing the neurotransmitters to the synaptic cleft, then the neurotransmitters will interact with the postsynaptic terminal receptors of a different neuron to open their ion channels and generate a new action potential.

b - the respond is innate and varies over time.

good luck!
