Question:
differences between neurons and other cells

Answer:
endothelial cells with tight junctions, pericytes, astrocytes
Question:
divisions of the autonomic nervous system
Answer:
sympathetic (fight or flight) and parasympathetic (rest and digest)
Question:
three ways resting potential is maintained
Answer:
Na+/K+ pump, semipermeable membrane, ion channels (Na+ closed, K+ leaky)
Question:
why are leaky K+ channels ok
Answer:
K+ should move in based on the electrical gradient, but out based on the
