At rest, where can Cl- be found in higher concentrations?

• inside the neuron

• outside the neuron

• equally inside and outside

• huh? Cl-?

• oligodendrocytes

• microglia

From the following where are you likely to find a large number of voltage gated Na+ channels?

• axon hillock

• soma

• dendrites

• synaptic cleft

At rest, what makes K+ want to leave the cell?

• concentration gradient

• electrostatic pressure

• Na+/K+ pump

• all of these

What part of the neuron releases neurotransmitters?

• axon terminal

• axon

• dendrites

• soma

• dendritic spines

Which of the following is false about when the neuron is at rest?

• Cl- channels are closed

• Concentration gradient wants to push K+ outside of the cell

• Electrostatic pressure wants to push Cl- outside of the cell

• Na+ channels are closed
