Question : How many statements are incorrect for neuron?i. Neurons are excitable cells because their membranes are in a polarised state ii. Different types of ion channels are present on the neural membrane iii. Ion channels are selectively permeable to different ionsiv. When a neuron is not conducting any impulse the axonal membrane is comparatively less permeable to K^(+) and nearly impremeable to Na^(+)v. Resting membrane is impermeable to negatively charged proteins present in the axoplasm. vi. The ionic gradients across the resting membrane are maintained by the active transport of ions by the sodium-potassium pump.vii. In sodium-potassium pump2Na^(+) transported outwards and 3K^(+) into the cell.
