Question
A depolarization that happens in a sensory receptor on stimulation is known as a ________ potential.
Solution
A depolarization that occurs in a sensory receptor upon stimulation is known as a receptor potential. This type of potential is critical in the process of sensory transduction, where an external stimulus is converted into an electrical signal in sensory neurons. When a sensory receptor is activated by a specific stimulus (such as light, sound, or pressure), it undergoes a change in membrane permeability, leading to depolarization and generating a receptor potential. If the receptor potential is sufficient to reach a certain threshold, it can trigger an action potential that will then propagate along the sensory neuron, ultimately resulting in the perception of the stimulus in the central nervous system.
