Action potential is also termed as

Options

A. Nerve implse
B. Reflex action
C. Repolarisation
D. Polarisation

Answer

**Step-by-Step Solution:**

1. **Understanding Action Potential**: Action potential is a term used to describe the rapid change in membrane potential that occurs when a neuron transmits a signal. It is a crucial process in neural communication.

2. **Resting State of Neurons**: When a neuron is at rest, it is polarized, meaning there is a difference in charge across its membrane. The inside of the neuron is negatively charged compared to the outside, typically around -70 millivolts.

3. **Depolarization**: When a stimulus reaches the neuron, it causes depolarization. This means that sodium channels open, allowing sodium ions to rush into the neuron, making the inside more positive.

4. **Definition of Action Potential**: The term "action potential" refers to this rapid depolarization and subsequent repolarization of the neuron as it conducts an impulse. It is the potential difference across the membrane during this active state.

5. **Conclusion**: Therefore, action potential is also referred to as a "nerve impulse." This term emphasizes the function of action potential in transmitting signals along neurons.

**Final Answer**: Action potential is also termed as "nerve impulse."
