Hello, everyone and welcome to today's video. So which of the following cranial bones allow this P cord to pass through to the brain. As answer choice. A we have the frontal bone B, that's the por bone, C, the bone d, the occipital bone. Well, let's go over each of these so that we may solve the problem. First of all, we have a which is the frontal bone. Now, this is going to be forming the forehead and the upper part of the eye sockets. It is not going to allow this spinal core located at the back of the head to pass through to the brain. So we're going to cancel it out. Then we have B which is the temporal bone. Now, the temporal bones form to the sides of the skull and contain the ear canal on the inner ear. This is not going to be allowing the spinal cord to pass through to the brain. So we're also going to cancel it out. Then we have the ethmoid bone. This ethmoid bone is going to be forming the roof of the nasal cavity. The spinal cord is not going to be passing through here So we're going to cancel it out. And finally, we have the which is the occipital bone. Now, this is going to be forming the back of this cold and it's, it's going to contain something called the ramen magnum, which is going to be allowing the spinal cord to pass through to the brain. And therefore, this is going to be making answer choice, the occipital bone, the correct answer for this question. I really hope this helped you and I hope to see you on the next one.
