When a neuron is in resting state, i.e., not conducting any impulse, the axonal membrane is :

During resting condition, the axonal membrane is

In a neuron (axon) at rest the concentration of Nat is

(A ): When a capacitor is getting charged the conduction current in the connecting wires at any instant is equal to the displacement current in between the capacitor plates. (R) : Conduction current is always greater than the displacement current.

What happens when two solutions of different concentrations are separated by an egg membrane ? State the reason.

Consider the situation shown in the figure. If the current I in the long straight conducting wire XY is increased at a steady rate then the induced e.m.f..s in loops A and B will be

Consider that you are passing by a garbage disposal area and you immediately cover your nose. Arrange the events belown in a logical order by marking them from (i) to (v) to trace the events that happen in the nervous system from detection of foul smell (stimulus generation) to covering your nose (response). (i) At the end of the axon, electrical impulse releases chemicals. (ii) Stimulus received by the dendritic cells of a neuron sets off chemical reaction that creates an electrical impulse. (iii) Electrical impulse transmitted through cell body and axon. (iv) The chemicals cross the synapse and reach the next neuron. Similarly, the electrical impulse crosses several neurons. (v) Finally, the impulse is delivered from neuron to the gland that helps in recognition of the foul smell and muscle cells that help in covering the nose.
