Meninges

Aka: Meninges, Dura Mater, Arachnoid Mater, Pia Mater
  1. Definition
    1. Meninges
      1. Membranous lining (3 layers) of the brain and spinal cord
  2. Anatomy: Meningeal Layers
    1. General
      1. Mnemonic: PAD
    2. Pia Mater (inner layer, adjacent to brain)
      1. Inner layer of the Meninges (adjacent to the brain)
      2. Vascular layer (contains the major intracranial arteries including the Circle of Willis)
    3. Arachnoid Mater
      1. Connective tissue space between the dura and the pia
      2. Subarachnoid space separates the arachnoid from the pia
        1. Contains cerebrospinal fluid
        2. Subarachnoid Hemorrhage occurs in this space
    4. Dura Mater (outer layer, adjacent to skull)
      1. Thick, durable, outer layer of the Meninges (adjacent to the skull)
      2. Composed of two layers of connective tissue between which run cerebral veins known as sinuses
      3. Forms two additional barriers between intracranial components
        1. Falx Cerebri (divides the Cerebral Hemispheres)
        2. Tentorium cerebelli (divides the Cerebrum from the Cerebellum)
      4. Pathophysiology
        1. Subdural Hemorrhage occurs when veins bridging the brain and dural sinuses rupture
        2. Epidural Hemorrhage occurs when the middle meningeal artery ruptures (between the dura and skull)

Arachnoid mater (C0003707)

Definition (MSH) A delicate membrane enveloping the brain and spinal cord. It lies between the PIA MATER and the DURA MATER. It is separated from the pia mater by the subarachnoid cavity which is filled with CEREBROSPINAL FLUID.

Meninges (C0025285)

Definition (SCTSPA) Las tres membranas que rodean al cerebro y la médula espinal, constituidas por la duramadre, la piamadre y la aracnoides. La piamadre y la aracnoides juntas constituyen las leptomeninges
Definition (SNOMEDCT_US) The three membranes that surround the brain and spinal cord, consisting of the dura mater, arachnoid, and pia mater. The pia and arachnoid in combination are referred to as the leptomeninges.
Definition (NCI) Any one of three membranes that surround the brain and spinal cord.
Definition (NCI_NCI-GLOSS) The three thin layers of tissue that cover and protect the brain and spinal cord.
Definition (NCI_CDISC) Any one of three membranes that surround the brain and spinal cord. (NCI)
Definition (CSP) three membranes covering of the brain and spinal cord; named the dura mater, pia mater and arachnoid.
Definition (MSH) The three membranes that cover the BRAIN and the SPINAL CORD. They are the dura mater, the arachnoid, and the pia mater.

Pia Mater (C0031869)

Definition (NCI) The delicate, highly vascular, innermost membrane encasing the brain and spinal cord.
Definition (CSP) innermost layer of the leptomeninges, which adheres to the brain and spinal cord and conforms to all the irregularities on their surfaces.
