Larger influx of sodium ions into the nerve cell is called
1 Depolarization
2 Action potential
3 Re polarization
4 Positive feedback regulation
Explanation:
A When there is a larger influx of sodium ions into a nerve cell, it leads to depolarization, which is a change in the cell membrane potential. A positive feedback cycle rapidly moves the membrane potential toward its peak value, which is close but not equal to the \(\mathrm{Na}^{+}\)equilibrium potential.

Acetylcholinesterase help in breaking
1 Synapse
2 Dendrites
3 Acetylcholine
4 Axon
Explanation:
B Acetylcholinesterase enzyme is found in the synapse. This enzyme decomposes the acetylcholine in to choline and acetic acid. It breakdowns or hydrolyses acetylcholine and naturally occurring neurotransmitters into acetic acid and choline.

Which of the following is not considered as a secondary messenger?
1 Acetylcholine
2 cAMP
3 \(\mathrm{Ca}^{2+}\)
4 Diacylglycerol
Explanation:
A Secondary messengers are molecules that are produced inside the cell in response to signal from outside of the cell. They amplify the signal and relay it to other. \(\mathrm{Ca}^{2+}\), diacylglycerol, cAMP are examples of secondary messenger. Acetylcholine is the neurotransmitter in the parasympathetic nervous system (the part of the autonomic nervous system) that contracts smooth muscles, dilates blood vessels, increases bodily secretions, and decreases heart rate.

Action potential is generated by
1 \(\mathrm{Na}\)
2 \(\mathrm{K}^{+}\)
3 \(\mathrm{Ca}\)
4 \(\mathrm{Cl}^{-}\)
Explanation:
A An action potential is generated by the rapid influx of \(\mathrm{Na}^{+}\)ions followed by a slightly slower influx of \(\mathrm{K}^{+}\)ions. An action potential is generated in the body of the neuron and propagated through its axon.
