Cells become more negative during hyperpolarization

Leak sodium channels are the primary determinant of the resting membrane potential of a neuron

The parasympathetic nervous system is considered part of the afferent portion of the peripheral nervous system

Terminal buttons of neurons release neurotransmitters

Action potentials will travel in both directions from the middle of a motor neuron

Larger diameter neurons will propagate action potentials at a slower velocity compared to smaller diameter neurons

Voltage-gated potassium channels cause the rapid upstroke of an action potential

The afterhyperpolarization phase of an action potential is due to current moving through voltage-gated potassium channels

Activation of ligand gated Cl- channels by neurotransmitters in the synaptic cleft with typically lead to EPSP’s

The “tightness” of the blood-brain barrier results mostly from the action of __________, a type of glial cell.

The sodium equilibrium potential using an extracellular Na+ concentration of 145 mEq/L and an intracellular concentration of 14 mEq/L would be about

The resting membrane potential is closest to the equilibrium potential for:

Hyperkalemia would _______resting membrane potential of the cell.

Neurotransmitter release would be inhibited by:

What is NOT true of the relative refractory period?

Chemicals that stimulate action potentials in postsynaptic cells are called:

What action produces an IPSP on the postsynaptic membrane (choose all that apply)?
