  2. Arachnoid mater - Wikipedia

    en.wikipedia.org/wiki/Arachnoid_mater

    The arachnoid mater covering the brain is referred to as the arachnoidea encephali, and the portion covering the spinal cord as the arachnoidea spinalis. The arachnoid and pia mater are sometimes considered as a single structure, the leptomeninx, or the plural version, leptomeninges (lepto, from the Greek root meaning "thin" or "slender").

  3. 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 ]

  4. Arachnoid - Wikipedia

    en.wikipedia.org/wiki/Arachnoid

    Arachnoid (astrogeology), a geological structure found only on the planet Venus; Arachnoid (botany), referring to organs with a cobwebby exterior appearance; Arachnoid granulation, small protrusions of the arachnoid mater; Arachnoid mater, a layer of the meninges, membranes that contain the central nervous system

  5. Meningitis - Wikipedia

    en.wikipedia.org/wiki/Meningitis

    The outermost membrane, the dura mater, is a thick durable membrane, which is attached to both the arachnoid membrane and the skull. In bacterial meningitis, bacteria reach the meninges by one of two main routes: through the bloodstream (hematogenous spread) or through direct contact between the meninges and either the nasal cavity or the skin.

  6. Meninges - Wikipedia

    en.wikipedia.org/wiki/Meninges

    The middle element of the meninges is the arachnoid mater, or arachnoid membrane, so named because of its resemblance to a spider web. It cushions the central nervous system. This thin, transparent membrane is composed of fibrous tissue and, like the pia mater, has an outer layer of tightly packed flat cells, forming the arachnoid barrier. [8]

  7. Leptomeningeal collateral circulation - Wikipedia

    en.wikipedia.org/wiki/Leptomeningeal_collateral...

    Leptomeningeal collaterals lie within the leptomeninges, the two deep layers of the meninges called the pia mater and the arachnoid mater. [4] Their diameter has been measured at approximately 300 micrometers, [ 5 ] but there is variability between individuals in the size, quantity and location of these vessels, and between either hemisphere ...

  8. Subarachnoid cisterns - Wikipedia

    en.wikipedia.org/wiki/Subarachnoid_cisterns

    Although the pia mater adheres to the surface of the brain, closely following the contours of its gyri and sulci, the arachnoid mater only covers its superficial surface, bridging across the gyri. This leaves wider spaces between the pia and arachnoid and the cavities are known as the subarachnoid cisterns. [citation needed]
