Answer to Question 1

ANS: C
The membranous covering of the central nervous system (CNS), referred to as meninges, lines the cranium and covers the brain and spinal cord. The three distinct layers are the dura mater (in direct contact with the cranium), arachnoid (a weblike space), and pia mater (in direct contact with the surface of the brain).

Answer to Question 2

ANS: B
A Mayfield headrest fits on to a standard OR bed. The Mayfield headrest conforms to the contours of the patient's head like a horseshoe. The Mayfield skull clamp provides stability during lengthy procedures.
