With regard to the process of neural transmission, a refractory period refers to a time interval in whichA. a neuron fires more rapidly than usualB. an electrical charge travels from a sensory neuron to a motor neuronC. positively charged ions are pumped back outside a neural membraneD. am individual reflexively withdraws from a pain stimulusE. dendrites transmit more electrical signals to axons
In transmitting sensory information to the brain, an electrical signal travels from the ________ of a single neuron.A. cell body to the axon to the dendritesB. dendrites to the axon to the cell bodyC. axon to the cell body to the dendritesD. dendrites to the cell body to the axonE. axon to the dendrites to the cell body
Increasing excitatory signals above the threshold for neural activation will not affect the intensity of an action potential. This indicates that a neuron"s reaction isA. inhibited by the myelin sheathB. delayed by the refractory periodC. an all-or-none responseD. dependent on neurotransmitter moleculesE. primarily electrical rather than chemical
Your friend is taking her first psychology class. She comes to you saying, "I don"t understand why we are studying the brain; I thought this was a psychology class."
