sensory

What is the functional classification for neurons that carry information from peripheral receptors to the central nervous system?

motor

What is the functional classification for neurons that carry information from the central nervous system to peripheral effector organs?

ganglia

What are clusters of neuronal cell bodies in the peripheral nervous system called?

astrocyte

What type of glial cell is responsible for supporting neurons and maintaining the blood/brain barrier?

axon

What do we call neuronal processes that transmit membrane potentials away from the neuronal cell body?

threshold

What is the smallest stimulus that is capable of initiating an action potential called?

relative refractory period

What do we call the period during which initiation of an action potential requires a higher than normal threshold stimulus?

absolute refractory period

What do we call the period during which an action potential cannot be initiated, regardless of the strength of the stimulus?
