Communicate signals to target cells (other neurons or … WebHowever, the presence of Schwann cells does not directly affect the opening or closing of ion channels on the nerve cell membrane. Thus, options (a), (b), (c), and (d) are incorrect. In conclusion, Schwann cells impact nerve cells by myelinating their axons, thereby increasing the speed of nerve impulses.
