At the end of repolarization, the nerve membrane gets hyperpplarized. Why ?

Text Solution

Verified by Experts

1. In a neuron the reversal of membrane potential inside the axolemna to negative occurs due to the efflux of `K^(+)` ions which is called Repolarization.
If repolarization becomes more negative than the resting potential - 70 mV to about -90 mV, it is called Hyperpolarization.
During hyperpolarization the `Na^(+)` voltage gate remains closed.

Figure shows a light rod of length l rigidly attached to a small heavy block at one end and a hook at the other end. The system is released from rest with the rod in a horizontal position. There is a fixed smooth ring at a depth h below the initial position of the hook and the hook gets into the ring as it reaches there. What should be the minimum value of h so that the block moves in a complete circle about the ring?
