蛛网膜下隙
• Position: lies between pi a and arachnoid maters co ntaining cerebrospinal fl uid
• Terminal cistern 终池: th e largest part of subarac hnoid space extending fro m termination of spinal c ord to level of S2, where it is occupied by nerves of cauda equina, so it is the best site for a lumba r puncture

The Meninges of Brain and Spinal Cord
• The spinal cord and brain are surrounded by three membranes, the meninges. Named from the outside inward they are the dur a mater, arachnoid, and pia mater.
Lumbar spinal puncture (spinal tap)
Spinal pia mater 软脊膜
• A delicate vascular membran e that closely invests the spinal cord
• Denticulate ligament齿状韧 带: consist of 21 pairs tri angular ligaments extending from spinal cord on each si de between anterior and pos terior roots of spinal nerv es to spinal dura mate; th ese ligaments help to fix p osition of spinal cord.

Characters
• A thick and dense inel astic membrane that co mposed of two layers, an inner or meningeal and outer or endosteal
• It is in loose contact with calvaria, and mos t strongly adherent to base of skull
