Spinal arachnoid mater 脊髓蛛网膜 Characters ◼ A thin, delicate, tubular membran loosely investing spinal cord ◼ Above, it is continuous with cerebral arachnoid mater
Subarachnoid space 蛛网膜下隙 Position: lies between pia and arachnoid maters containing cerebrospinal fluid Termina| cistern终池:the largest part of subarachnoid space extending from termination of spinal cord to level of s2. where it is occupied by nerves of cauda equina, so it is the best site for a lumbar puncture

Spinal pia mater软脊膜 a delicate vascular membrane that closely invests the spinal cord Denticulate ligament齿状韧带 consist of 21 pairs triangular ligaments extending from spinal cord on each side between anterior and posterior roots of spinal nerves to spinal dura mate; these ligaments help to fix position of spinal cord filum terminale: an extension of pia beyond conus medullaris
