What is electrical potential?

The difference in the concentration of charged particles between two points, measured as voltage.

2
New cards

What is electrical current?

The flow of charged particles from one point to another.

3
New cards

What does it mean when something is polarized?

It has an electrical potential (a charge difference across a membrane).

4
New cards

What is resting membrane potential (RMP)?

The charge difference across the plasma membrane of a cell at rest.

5
New cards

What is the resting membrane potential (RMP) of neurons?

-70 mV.

6
New cards

What does the -70 mV resting membrane potential mean?

The inside of the neuron is more negative than the outside.
