A sensory receptor is a structure in the body that responds to a specific stimulus, such as light, sound, or temperature. This allows for the detection of these stimuli and the transmission of this information to the brain for processing. Option A is incorrect because a chemical released by neurons is not a structure, and while it may play a role in sensory perception, it is not the definition of a sensory receptor. Option B is incorrect because a learned behavior is not a physical structure in the body. Option D is incorrect because inherited traits are genetic characteristics, not physical structures that respond to stimuli.
