Neurons conduct an action potential

	when sodium is pumped out of the neuron.
	when molecular gates open to allow sodium ions into a neuron.
	when the electrical stimulation dips below -70 millivolts.
	only if surrounded by a myelin sheath.

	amounts of DNA and RNA.
	types of neurotransmitters on either side of the nerve cell membrane.
	types of neurons inside and outside the nerve cell membrane.
	concentrations of ions on either side of the nerve cell membrane.

	resting potential.
	equilibrium potential.
	state of potential nerve energy.
	action potential.
