  2. Dura mater - Wikipedia

    en.wikipedia.org/wiki/Dura_mater

    The dura mater covering the spinal cord is known as the dural sac or thecal sac, and only has one layer (the meningeal layer) unlike cranial dura mater. The potential space between these two layers is known as the epidural space , [ 5 ] which can accumulate blood in the case of traumatic laceration to the meningeal arteries .

  3. Dural venous sinuses - Wikipedia

    en.wikipedia.org/wiki/Dural_venous_sinuses

    The walls of the dural venous sinuses are composed of dura mater lined with endothelium, a specialized layer of flattened cells found in blood and lymph vessels.They differ from other blood vessels in that they lack a full set of vessel layers (e.g. tunica media) characteristic of arteries and veins.

  4. Arachnoiditis - Wikipedia

    en.wikipedia.org/wiki/Arachnoiditis

    Arachnoiditis is an inflammatory condition of the arachnoid mater or 'arachnoid', one of the membranes known as meninges that surround and protect the central nervous system. The outermost layer of the meninges is the dura mater (Latin for hard) and adheres to inner surface of the skull and vertebrae. [ 1 ]

  5. Longitudinal fissure - Wikipedia

    en.wikipedia.org/wiki/Longitudinal_fissure

    All three meninges of the cortex (dura mater, arachnoid mater, pia mater) fold and descend deep down into the longitudinal fissure, physically separating the two hemispheres. Falx cerebri is the name given to the dura mater in-between the two hemispheres, whose significance arises from the fact that it is the outermost layer of the meninges ...

  6. Arachnoid granulation - Wikipedia

    en.wikipedia.org/wiki/Arachnoid_granulation

    Arachnoid granulations (also arachnoid villi, and pacchionian granulations or bodies) are small outpouchings of the arachnoid mater and subarachnoid space into the dural venous sinuses of the brain. The granulations are thought to mediate the draining of cerebrospinal fluid (CSF) from the subarachnoid space into the venous system. [1]

  7. Cerebrospinal fluid leak - Wikipedia

    en.wikipedia.org/wiki/Cerebrospinal_fluid_leak

    Cerebrospinal fluid is produced by the choroid plexus in the ventricles of the brain and contained by the dura and arachnoid layers of the meninges. [23] [42] [64] The brain floats in CSF, which also transports nutrients to the brain and spinal cord. As holes form in the spinal dura mater, CSF leaks out into the surrounding space.

  8. Arachnoid mater - Wikipedia

    en.wikipedia.org/wiki/Arachnoid_mater

    The arachnoid mater and dura mater are very close together throughout the cranium and spinal canal all the way to sacral vertebra S2, where the two layers fuse into one and end in the filum terminale, which attaches to the coccygeal end of the spinal canal. Sandwiched between the dura and arachnoid maters lie some veins that connect the brain's ...

  9. Human brain - Wikipedia

    en.wikipedia.org/wiki/Human_brain

    Between the arachnoid mater and the pia mater is the subarachnoid space and subarachnoid cisterns, which contain the cerebrospinal fluid. [11] The outermost membrane of the cerebral cortex is the basement membrane of the pia mater called the glia limitans and is an important part of the blood–brain barrier. [12]
