The spinal cord and brain are surrounded by three membranes, the meninges. Named from the outside inward they are the dura mater, arachnoid, and pia mater. The meninges of spinal cord ? Spinal dura mater 硬脊膜 ? Spinal arachnoid mater脊髓蛛網(wǎng)膜 ? Spinal pia mater 軟脊膜 Spinal dura mater 硬脊膜 Characters ? Above, attached to circumference of foramen magnum ? Below, bees thinner at level of S2, invests filum terminale to attach at back of coccyx Epidural space 硬膜外隙 ? Position: lies between spinal dura mater and periosteum of vertebral canal ? Contents: a quantity of loose connective tissue, fat, lymphatic vessels and vertebral venous plexus, the spinal nerves on each side pass through the epidural space which is applicable for block anesthesia Subdural space硬膜下隙 Spinal arachnoid mater 脊髓蛛網(wǎng)膜 Characters ?

Position: lies between pia and arachnoid maters containing cerebrospinal fluid ?
