Hello, everyone and welcome to today's video. So today, we need to identify the incorrectly matched pair. Now let's go over each of our answer choices so that we may solve this problem. First of all, we have a frontal cranial bone that forms the forehead. This is going to be true. Therefore, we're going to move on. Then we have the and this is going to be the cranial bone that forms the lateral aspects of the skull. Again, this is going to be true. So we're going to move on. Then we have the occipital, which is going to be the cranial bone that forms most of the base of the skull or the back. This is also true. So we're going to be moving on. Now, we have the Zygomatic and this is stated to be the cranial boom that forms the inferolateral aspects of the skull. Well, this is going to be false. But why as it turns out this Zygomatic is going is not going to be a cranial boom. It is going to be a facial bone that forms the shake and part of the orbit. Now, the cranial bone that forms the inferolateral aspects of the skull is going to be the temporal. So that should be the match there. And therefore that makes answer choice d or incorrectly matched pair. So we're going to highlight it. So we have that Zygomatic cranial bone that forms the inferolateral aspects of the skull is or incorrectly matched pair. And the final answer for this question, I really hope this helped and I hope to see you on the next one.
