NEET PG DENTAL EXAM

Detailed explanation-1: -This means that the interior of the cell is negatively charged relative to the outside. Hyperpolarization is when the membrane potential becomes more negative at a particular spot on the neuron’s membrane, while depolarization is when the membrane potential becomes less negative (more positive).

Detailed explanation-2: -If you are alert, you notice that both the sodium and the potassium ions are positive. Neurons actually have a pretty strong negative charge inside them, in contrast to a positive charge outside. This is due to other molecules called anions. They are negatively charged, but are way too big to leave through any channel.

Detailed explanation-3: -If the membrane potential becomes more negative than it is at the resting potential, the membrane is said to be hyperpolarized.

Detailed explanation-4: -When the inside of the plasma membrane has a negative charge compared to the outside, the neuron is said to be polarized. Any change in membrane potential tending to make the inside even more negative is called hyperpolarization, while any change tending to make it less negative is called depolarization.
