What is the resting membrane potential of nerve fiber?
1 \(+75 \mathrm{mV}\)
2 \(+45 \mathrm{mV}\)
3 \(-70 \mathrm{mV}\)
4 \(-45 \mathrm{mV}\)
Explanation:
C In most neurons the resting potential has a value of approximately \(-70 \mathrm{mV}\). The resting potential is mostly determined by the concentrations of the ions in the fluids on both sides of the cell membrane and the ion transport proteins that are in the cell membrane.

When ' \(A\) ' stands for Axon. ' \(D\) ' for Dendrites. ' \(S\) ' for Synapse and 'CB' for Cell body, a typical sequence of structures between a receptor and an efferent is
C Typical sequence of structures between a receptor and an efferent is Dendrites \(\rightarrow\) cell body \(\rightarrow\) Axon \(\rightarrow\) Synapse \(\rightarrow\) Dendrite \(\rightarrow\) Cell body \(\rightarrow\) Axon. This means the signal travel from dendrite (D) to the cell body \((\mathrm{CB})\), then down the axon (A), through a synapse \((S)\), and repeats the process until it reaches the efferent pathway.

During the conduction of nerve impulse, the repolarization occurs with the
1 influx of \(\mathrm{K}^{+}\)ions
2 influx of \(\mathrm{Na}^{+}\)ions
3 efflux of \(\mathrm{K}^{+}\)ions
4 efflux of \(\mathrm{Na}^{+}\)ions
Explanation:
C During the repolarization phase of nerve impulse conduction, there is an efflux (outward movement) of \(\mathrm{K}^{+}\)ions from the cell, which helps to restore the resting membrane potential after the depolarization phase.

In the axon of motor nerve fiber, the nerve impulse travels
1 Towards cell body
2 Away from cell body
3 Away from synapse
4 In both directions
Explanation:
B In a motor nerve fiber, the direction of nerve impulse transmission is unidirectional. The nerve impulse travel away from the cell body, toward the muscle or target organ it innervates.
