Lesson 6.2: Learning the Key Terms

is the re-establishment of a polarized state in a cell after depolarization

repolarization

when the inside of a cell is more negatively charged than the outside, it is

polarized

is the time between the completion of the action potential and repolarization

refractory period

the ability of a neuron to transmit a nerve impulse is called

conductivity

are involuntary stimuli transmitted to skeletal muscles from neural arcs in the spinal cord

somatic reflexes

are involuntary stimuli transmitted to cardiac and smooth muscle

autonomic reflexes

are simple, rapid, involuntary, programmed responses to stimuli

reflexes

a cell membrane that is what is more positively charged in the inside than the outside

depolarized

an action potential that rapidly skips from node to node on my myelinated neurons is experiencing

saltatory conduction

is an electrical charge that travels along a nerve fiber when stimulated

nerve impulse
