It is in loose contact with calvaria, and most strongly adherent to base of skull
THE MENINGES AND BLOOD VESSELS OF BRAIN AND SPINAL CORD, AND THE CEREBROSPINAL FLUID 脑和脊髓的被膜、血管及脑脊液循环
MENINGES OF BRAIN AND SPINAL CORD
The spinal cord and brain are surrounded by three membranes, the meninges.
蛛网膜下隙的下部，自脊髓下 端至第2骶椎扩大为终池，内有 马尾。
脊髓被膜和腔隙
The meninges (coverings) of spinal cord
*spinal dura mater,arachnoid and spinal pia mater *epidural space,subarachnoid space and denticulate ligaments
CEREBRAL DURAL MATER 硬脑膜
Characters
A thick and dense inelastic membrane that composed of two layers, an inner or meningeal and outer or endosteal
由两层合成, 间有丰富的血管和 神经
பைடு நூலகம்
SPINAL DURA MATER 硬脊膜
Characters
A dense, fibrous membrane that encloses the spinal cord and cauda equina（马尾） Above, attached to circumference of foramen magnum （枕骨大孔） Below, becomes thinner at level of S2, invests filum terminale（终丝）to attach at back of coccyx On each side, continuous with external membrane of spinal nerves at intervertebral foramina（椎间孔）
Named from the outside inward they are • Dura mater 硬膜 • Arachnoid mater 蛛网膜 • Pia mater 软膜
THE MENINGES OF SPINAL CORD
Spinal dura mater 硬脊膜 Spinal arachnoid mater脊髓 蛛网膜 Spinal pia mater 软脊膜
Pia mater
Arachnoid mater Dural root sleeve
Posterior ramus
Anterior ramus Spinal nerve
Dura mater
Posterior rootlets Denticulate lig. Posterior root Spinal ganglion
Anterior longitudinal lig.
12th rib
Intercristal line (L4)
Iliac crest
THE MENINGES OF BRAIN
Cerebral dural mater 硬脑膜 Cerebral arachnoid mater 脑蛛网膜 Cerebral pia mater 软脑膜
SPINAL ARACHNOID MATER 脊髓蛛网膜
半透明的薄膜 ，位于硬脊膜与 软脊膜之间，与脑蛛网膜相延续
SPINAL PIA MATER 软脊膜
紧贴脊髓表面，并延伸至脊髓的 沟裂中，向上经枕骨大孔与软脑 膜相延续，向下在脊髓圆锥下端 移行为终丝。
软脊膜在脊髓两侧脊神经前、后 根之间形成齿状韧带
Epidural space 硬膜外隙
• Position: lies between spinal dura mater 硬脊膜and periosteum of vertebral canal 椎管内膜
• Contents: a quantity of loose connective tissue, fat 脂肪, lymphatic vessels 淋巴and vertebral venous plexus 静脉丛, the spinal nerves 脊神 经根on each side pass through the epidural space which is applicable for block anesthesia
Anterior root
C4
L2
Lumbar spinal puncture (spinal tap)
Skin
Supraspinous fascia
Interspinal lig.
Yellow lig.
Posterior longitudinal lig.
Intervertebral disc.
• 硬膜外麻醉
Subdural space 硬膜下隙
SUBARACHNOID SPACE 蛛网膜下隙
Position: lies between pia and arachnoid maters containing cerebrospinal fluid
脊髓蛛网膜与软脊膜之间,充满 脑脊液
Terminal 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 （马尾）, so it is the best site for a lumbar puncture
