Comparatively more permeable to $K^+$ ions and nearly impermeable to negatively charged proteins

(B) The correct answer is $(B)$.During the resting stage,the axonal membrane is comparatively more permeable to $K^+$ ions and nearly impermeable to $Na^+$ ions.Furthermore,the membrane is nearly impermeable to the negatively charged proteins present in the axoplasm.This differential permeability,along with the action of the $Na^+-K^+$ pump,maintains the resting membrane potential.

Generation and conduction of Nerve Impulse

During resting potential,the axonal membrane is polarised. Indicate the movement of $+ve$ and $-ve$ ions leading to polarisation diagrammatically.

View Solution

Which of the following statements is/are correct?
$(a)$ The electrical potential difference across the resting plasma membrane is called the resting potential.
$(b)$ $Na^+$ ions are responsible for the generation of an action potential.

How does the conduction of a nerve impulse occur?

Easy

View Solution

Give scientific reasons:
$(1)$ There is no physical connection between sequential neurons,yet nerve impulses are conducted through them.
$(2)$ The neuroplasm of a neuron contains a high $K^+$ concentration during the maintenance of the resting potential.
