Hey, everyone. Let's take a look at this question together which of the following is being carried by anterolateral pathways. Is it answer choice? A vibration sensations, answer choice B, temperature sensations, answer choice C proprioceptors or answer choice D pressure receptors. Let's work this problem out together to try to figure out which of the following answer choices is being carried by those anterolateral pathways. So in order to solve this question, we have to recall what the anterolateral pathways are and what type of sensation or information is carried by those pathways, which we can recall that the anterolateral pathway such as the spinothalamic tract are responsible for carrying certain types of somatic sensations, which we know that those somatic sensations can include temperature. And the spinothalamic tract transmits information related to temperature and pain sensations from the body to the brain. So looking at our answer choices, we can identify answer choice B which says temperature sensations as the correct answer and all other answer choices are incorrect. Since the anterolateral pathways such as the spinothalamic tract do not carry vibration sensations, proprioceptor information or pressure receptor information. And answer choice B is the only correct answer choice. I hope you found this video to be helpful. Thank you and goodbye.
