Depolarization of a stimulated nerve is ...

Depolarization of a stimulated nerve is maintained by

A

`Ca^(++)`

B

`Cl^(-)`

C

`Mg^(++)`

D

`K^(+)`

Text Solution

Verified by Experts

The correct Answer is:
D
Efflux of `K^(+)` causes repolarization. Therefore it is the movement of `K^(+)` that maintains the depolarized state.
