Quizplus · Accepted Answer

The dura mater of the spinal cord is not attached to the inner surface of vertebrae, but the dura mater of the brain is attached to the inner surface of the cranial bones. This is a key difference between the meninges of the brain and the spinal cord. Additionally, denticulate ligaments are present in both the brain and spinal cord, but they serve different functions. In the brain, denticulate ligaments connect the pia mater to the dura mater, while in the spinal cord, they anchor the spinal cord to the dura mater. Therefore, choices A and B are incorrect, and choice D is incorrect because it states there are no differences when there is at least one significant difference between the two.
