Depolarization refers to the reversal of charges of neuron cell membrane, it occurs by moving in of 'Na' ions .
A nerve is depolarized when there is a shift in the resting membrane potential towards more positive values, usually triggered by the opening of voltage-gated ion channels. This initiates an action potential that allows for the transmission of electrical signals along the nerve cell.
False
There is electrical potential difference between out side of the cell and inside of the cell, in case of the polarized neuron. This electrical difference is lost in case of depolarization. That is what can be said roughly.
The most likely place you're going to find a sodium potassium pump would be in the muscle cell membrane. The sodium potassium pump reverses the electronegative potential once the cell has depolarized. In other words, it primes the muscle cell to be able to contract again.
Action potentials are short-lived, local changes in membrane potential that can be either depolarized or hyperpolarized. They are essential for transmitting electrical signals along neurons.
depolarized, which triggers an action potential and leads to muscle contraction.

-70 millivolts
Depolarized light refers to light in which the orientation of the electric field vectors is randomized in all directions. This means that the light is no longer vibrating in a single plane, making its polarization undefined. Depolarized light can be created by scattering or passing light through certain materials.

Once action Potential reaches Dendrides of the Neuron, the cell is Depolarized, causing the cell (neuron) to release a chemical signal, known as a nuerotransmitter, from the Pre-synsaptic cleft, where it will bind to recepters on the Post-synaptic cleft.
There is more potassium inside the cell during a resting period...as an action potential occurs, the cell becomes depolarized, or in other words there is an influx of sodium, allowing the membrane to open. As the action potential comes to an end, the cell repolarizes, meaning the levels of sodium rush outside of the cell again, while the potassium flows back in. As another action potential takes place, this happens over again.
