Their membranes are in a polarized state

Vedclass · Answer

(C) Neurons are considered excitable cells because their membranes are in a polarized state. In the resting state,the axonal membrane is more permeable to $K^+$ ions and nearly impermeable to $Na^+$ ions. This differential permeability,maintained by the $Na^+-K^+$ pump,creates an electrical potential difference across the membrane,known as the resting membrane potential. This state of polarization allows the neuron to respond to stimuli by generating an action potential.
