Describe the steps of sensory transduction when a touch receptor in the skin is activated
What will be an ideal response?
The steps of sensory transduction are as follows: 1 ) Before a stimulus arrives, the ion channels in the axolemma of the PNS sensory neuron are closed. 2 ) When a stimulus arrives, mechanically gated sodium ion channels open. Sodium ions enter the axoplasm, causing a temporary depolarization referred to as receptor potential. 3 ) If enough sodium ions enter that the membrane potential reaches threshold, voltage-gated sodium ion channels open. An action potential is triggered and it is propagated along the axon to the CNS.
