Question
When a neuron is an resting state, ie, not conducting any impulse, the axonal membrane is
Options
A.equally permeable to both Na+ and K+ ions
B.impermeable to both Na+ and K+ ions
C.comparatively more permeable to K+ ions and nearly impermeable to Na+ ions
D.comparatively more permeable to Na+ ions and nearly impermeable to K+ ions
Solution
Neurons are exitable cells because their membrane are in a polarised state. Different typesof selectively permeable channels are presents on the nural membrane . When a neuron isnot conducting any impulse, ie, resting, the axonal membrane is comparatively morepermeable to potassium ion (K+) and nearly impermeable to sodium ion (Na+)
