A loud crash makes you jump. Which of the following receptors would be most likely to detect the stimulus? (A) Pain receptors in your skin, (B) light receptors in your eyes, (C) sound receptors in your skin, (D) light receptors in your brain, or (E) sound receptors in your ears.
Several different sensory receptors exist in the human body, and they allow us to process and experience our surroundings. This question asks about the receptor that would detect the stimulus of a loud crashing noise. In order to answer this question, let’s discuss a few of the receptors found in the human body. Humans possess sound receptors in the ears, and these allow us to process auditory signals from our surroundings. We also possess pain receptors in the skin, which is why you may have experienced pain upon touching a sharp object. Light receptors exist in the eyes, and they allow us to see our surroundings. Several other receptors also exist, including those that allow us to detect temperature, chemicals, and pressure.
Now that we have covered some of the receptors involved in our answer choices, we are able to answer our question correctly. The sensation we are being asked about is a noise. A noise is a sound. So the correct receptor responsible for detecting this is likely a sound receptor. Sound receptors are found exclusively in the ears in humans. So the correct answer to this question is (E) sound receptors in your ears.
