What are the functions of neuroglia?Multiple ChoiceThey guide neurons to muscles, then pass neurotransmitters to the muscle cells.They serve as glue and scaffolding for neurons but have no physiological role.They sense changes in the environment and respond by sending electrical impulses.They support and bind nervous tissue and provide nutrients and growth factors to neurons by connecting them to blood vessels.
