During the propagation of a nerve impulse, the action potential results from the movement of
- AK+ ions from intracellular fluid to extracellular fluid
- BNa+ ions from extracellular fluid to intracellular fluid
- CK+ ions from extracellular fluid to extracellular fluid
- DNa+ ions from intracellular fluid to extracellular fluid.
View written solutionFree
Correct answer: B
Total sum of physio-electrochemical
changes that takes place along the length of
nerve fibre is known as nerve impulse.
Change in potential due to stimulation of nerve fibre is called action potential. During
propagation of nerve impulse, Na+ enters
inside so ( +ve) charge is formed inside the
membrane. K+ ions come out.
