During brain surgery, surgeons must cut through the scalp and a thick, leathery layer of the meninges in order to reach the brain. What is the name of this layer?

Question

BlackTom AI · Accepted Answer

The question asks for the name of the thick, leathery layer that must be cut through during brain surgery to reach the brain.
Option 1: Dura Mater. This is the correct identification: the dura mater is the outermost and toughest layer of the meninges, described as a thick, leathery membrane that encloses the brain and spinal cord, which explains why surgeons must cut through it first.
Option 2: Pia Mater. This is the innermost delicate layer that directly covers the brain's surface, not the thick protective outer layer, so it is not the layer described in the question.
Option 3: Arachnoid Mater. This middle, web-like layer lies between the dura and pia mater. While it is part of the meninges, it is not the thick leathery layer the surgery must traverse first.
Option 4: Choroid Plexus. This structure resides within the brain's ventricles and produces CSF; it is not a meningeal layer, nor is it encountered as the outer protective layer during scalp-to-brain access.
Option 5: Foramen Magnum. This is an anatomical opening at the base of the skull, not a meningeal layer, so it cannot be the layer described in the question.
