This document contains a 10 question neurophysiology quiz that covers topics like the parts of neurons, membrane potentials, action potentials, and the roles of different neuroglial cells. The questions test knowledge of which cell types carry signals towards the brain, identify the part of the neuron that sends signals to the next neuron, and recognize which neuroglia form the myelin sheath in the peripheral nervous system. Additional concepts addressed include the resting membrane potential of neurons, how neurons respond when sodium or potassium channels open, what depolarization and hyperpolarization refer to, the functions of astrocytes and oligodendrocytes, and properties of action potentials and EPSPs.
