Question

Nerve impulse is a

• A. Physical process
• B. Chemical process
• C. Effected process
• D. Electron-chemical process

Answer 1

Answer: (D)

Electron-chemical process

A nerve impulse is an electrochemical signal. The nerve cells are activated by the stimulus from the brain which opens the voltage-gated ion channels and helps in the depolarization of nerves. The waves of depolarization are conducted all along the axon and reach the nerve terminal where it activates the synaptic vesicles which release the chemicals known as neurotransmitters which conduct the impulse to the another neuron.

So, the correct answer is option D.
