- neurons, neuroglia; neuroglia outnumber neurons

- The parallel processing and interpretation of sensory information to determine the appropriate response
5 True/False questions
microglia → do not conduct nerve impulse; support, nourish, and protect neurons; special type of connective tissue for nervous system
reverse polarization → membrane 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
if transmission is _______ the NT-receptor reaction will depolarize → 31; carry info to and from spinal cord
CHART! → peripheral-somatic and autonomic-sympathetic (arousing) and parasympathetic (calming), central
saltatory conduction → occurs in myelinated axons; it's faster
