Hey, everyone. Let's take a look at this question together. The first order somatic sensory neurons are part of the larger somatosensory pathway that enables the perception of what is it? Answer choice, a touch, answer choice B image answer choice C sound or answer choice D light. Let's work this problem out together to try to figure out which of the following answer choices are associated with first order somatic sensory neurons. So in order to solve this question, we have to recall what we have learned about first order somatic sensory neurons to determine which of the following. Those first order somatic sensory neurons enable the perception of. And we can recall that first order somatic sensory neurons are neurons that are involved in the somatosensory pathway and are responsible for sensations related to touch, pressure, vibration, temperature and pain. So looking at our answer choices, we can identify answer choice, a touch as the correct answer. Since first order somatic sensory neurons are responsible for sensations related to touch. So answer choice A is the only correct answer choice as answer choice B image answer choice C sound and answer choice D light are all related to vision, hearing and sight, respectively, which vision, hearing and sight involve different sensory pathways and different types of sensory neurons. So answer choice A is the only correct answer choice. I hope you found this video to be helpful. Thank you and goodbye.
