Zoology - Neural Control and Coordination Question with Solution | TestHub

Neurons are excitable cells because their membrane are in a polarised state. Different types of selectively permeable channels are present on the neural membrane. When a neuron is not conducting any impulse, ie, resting, the axonal membrane is comparatively more permeable to potassium ion $\left({\mathrm{K}}^{+}\right)$and nearly impermeable to sodium ion $\left({\mathrm{Na}}^{+}\right)$.
