Final answer:
When dendrites receive a noxious stimulus, the typical response is initiation of an action potential.
Step-by-step explanation:
When dendrites receive a noxious stimulus, the typical response is initiation of an action potential. A noxious stimulus can depolarize the membrane of the dendrite, causing a decrease in the voltage across the membrane. If the depolarization reaches a certain threshold, the dendrite will generate an action potential, which is a self-propagating brief reversal of the resting membrane potential. This action potential can then be transmitted to downstream neurons to continue the signal.
