5 True/False questions

  1. microgliado not conduct nerve impulse; support, nourish, and protect neurons; special type of connective tissue for nervous system


  2. reverse polarizationmembrane is impermeable to Na+ but permeable to K+ and it rushes outside the cell down the concentration gradient, which restores the resting membrane potential to -70 mV

  4. CHART!peripheral-somatic and autonomic-sympathetic (arousing) and parasympathetic (calming), central


  5. saltatory conductionoccurs in myelinated axons; it's faster
