When a neuron is not conducting any impulse i.e. resting , the axonal membrance is

Assertion : When a neuron is not conducting any impulse, i.e. resting, the axoplasm inside the axon contains high concentration of K^(+) and negatively charged proteins and low concentration of Na^(+) . Reason : In resting, the axonal membrane is comparatively more permeable to K^(+) ions and nearly impermeable to Na^(+) ions. Similarly, the membrane is impermeable to negatively charged proteins present in axoplasm

Read the given statements and select the correct ones. (i)Autonomic neural system transmits impulses from the CNS to the voluntary organs and striated muscles of the body. (ii)Unmyelinated nerve fibres do not have Schwann cells which form the myelin sheath. (iii)Axonal membrane of a neuron while not conducting any impulse is comparatively more permeable to potassium ions (K^+) than to sodium ions (Na^+) (iv)A synapse is formed by the membranes of presynaptic neuron and a post synaptic neuron.

An action potential in the nerve fibre is produced when positive and negative charges on the outside and the inside of the axon membrane are reversed, because
