The Resting Neuron

Question

The resting neuron A) is polarized. B) has an internal (+) charge. C) has an internal negativity because of the outward leak of Na⁺. D) has an internal negativity because of the inward leak of K⁺.

Accepted Answer

The resting neuron is polarized with a negative charge inside and positive charge outside. This is due to the selective permeability of the cell membrane and the activity of ion channels. While there is some leak of ions such as Na+ and K+, it is not significant enough to completely offset the resting potential.
