Question

When dendrites receive a noxious stimulus, what is the typical response?

A) Enhanced synaptic transmission

B) Inhibition of neurotransmitter release

C) Initiation of an action potential

D) Promotion of cell division in the neuron

Answer 1

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.
