the resting potential is the potential difference across the neuron membrane while the neurone is at rest

# data[].attributes.body
The resting potential is the potential difference across the neurone is at rest. It is usually around -70mV to -60mV. It is maintained via the sodium potassium pump. Which pumps 3 Na+ ions in and 2 K+ ions.

# data[].attributes.body
That's when the sodium voltage gated channel is open and the sodium ions diffuse into the neurone causing the overall charge to become +40mV.

# data[].attributes.body
The resting potential is -70mv inside the cell because 3Na+ ions are pumped out of the neurone for every 2 k+ ions pumped in.

# data[].attributes.body
Resting potential is the voltage difference across the neurone membrane while the neurone is at rest. It is about between -70 - 60. The neurone is more negative inside than the outside. Three sodium ions pumped out of the outside. Sodium channels are closed so ions cannot move out of the neurone.

Dear Nana Kumi Darius III,

Neurone cell membranes are polarised, the resting potential is the potential difference across the neurone membrane while the neurone is at rest, the voltage of this is about -70mv to -60mv from inside to the outside. A neurone is more negative inside than outside. 3 na move out, 2k move in. Sodium and potassium channels are closed so ions cannot get back in or out of the neurone once pumped

# data[].attributes.body
The sodium-potassium pump restores resting potential by pumping Na+ ions back out the neurone and K+ ions back in

# data[].attributes.body
depolarisation of the neuron membrane so that the inside is more positive than the outside.
It’s is between +30 -+40mv inside the neuron compared to the outside.
The voltage gated Sodium Chanel opens in response to a stimuli
Sodium ions diffuse into the neuron down the concentration gradient this starts a nerve impulse.
The threshold for this to begin is -55mv and from here.
The all or nothing law applies

# data[].attributes.body
After an action potential has been created, sodium channels close while Potassium channels open. K ions diffuse out of the neurone down the concentration gradient created sodium-potassium pump. The neurone repolarises - the inside of the neurone becomes negative co the outside once again. Potassium channels are slow to close, so too many K ions diffuse out of it and the potential difference overshoots slightly. The sodium-potassium pumps restore resting potential by pumping

# data[].attributes.body
At 30mv sodium voltage gated channels close and potassium voltage gated channels open. Potassium ions diffuse out the neurone down the concentration gradient. The neurone repolarises where the inside of the neurone become negative compared to the outside

# data[].attributes.body
Repolarisation occurs when an action potential has been created (+30 or +40 mV). The sodium voltage gated channels close and the potassium voltage gated channels open. The potassium ions diffuse out of the neurone, down the concentration gradient causing it to repolarise.

# data[].attributes.body
- Sodium channels close
- Potassium channels open
- Potassium diffuses out of neurone
- Neurone repolarises
- Potassium channels are too slow to close therefore too many potassium ions diffuse out of the neurone. This causes hyperpolarisation.

# data[].attributes.body
Depolarisation is when the inside is more positive than the outside. The inside of the neurone is +40mV  compared to the outside. It occurs when the sodium channels open in response to a stimulus. Voltage gated sodium channels open so they diffuse into the neurone down the concentration gradient causing it to depolarise. Voltage gated potassium ions are closed.

# data[].attributes.body
Potassium channels OPEN, while Sodium channels CLOSE

In the Sodium-Potassium Pump- K+ ions diffuse out of the neurone down a concentration gradient.

In the end, the neurone repolarises since the inside of the neurone becomes more negative contrasting to the outside.

# data[].attributes.body
Repolarisation is happens when the action potential is created, this is when sodium gated channel closes and potassium gated channel opens. Potassium diffuses out of the neurone. Potassium channel are slow to close causing more potassium to diffuse making it hyperpolarised

The resting potential are maintained by the sodium and potassium pump also sodium channels and potassium channels.They active transport 3 Na+  ions out of 5he neurons and 2 K+ 8 ions in by using ATP and work against  concentration gradient. When The sodium and potassium channels opens they allow facilitated diffusion of either Na+ or K+ ions in or out of the neurons.
