    The cytoplasm immediately surrounding the nucleus is loaded with protein synthetic machinery and is called perikaryon, dendrites are usually shorter, tapering and much branched processes which may be one to several. These two are only present in nerve cells.

    Correct Option: D

    Total sum of physio-electrochemical changes that takes place along the length of nerve fibre is known as nerve impulse. Change in potential due to stimulation of nerve fibre is called action potential. During propagation of nerve impulse, Na+ enters inside so (+ve) charge is formed inside the membrane. K+ ions come out.
