II. Physiology

  1. Choroid Plexus: Formation of CSF
    1. Tufts of capillaries in Lateral Ventricles
    2. Produces CSF at 20 ml/hour
  2. Pathway
    1. Produced in both Lateral Ventricles
    2. Each ventricle drains into a foramina of Monro
    3. Both foramina drain into a single Third Ventricle
    4. CSF flows into aqueduct of Sylvius
    5. Enters Fourth Ventricle in posterior fossa
    6. Seeps into subarachnoid space via 3 small holes
    7. CSF in subarachnoid space cushions brain and spine
    8. CSF reabsorbed by arachnoid granules (top of brain)
    9. CSF empties into superior sagital sinus (venous)
  3. CSF Volume
    1. Total CSF in circulation: 140 ml
    2. Distribution
      1. Ventricles: 25 ml
      2. Subarachnoid space: 115 ml

Ontology: Cerebrospinal Fluid (C0007806)

Definition (FMA) Transudate contained in the subarachnoid space.
Definition (NCI) The fluid that is contained within the brain ventricles, the subarachnoid space and the central canal of the spinal cord. (NCI)
Definition (NCI) The fluid that flows in and around the hollow spaces of the brain and spinal cord, and between two of the meninges (the thin layers of tissue that cover and protect the brain and spinal cord). CSF is made by tissue called the choroid plexus in the ventricles (hollow spaces) in the brain.
Definition (UWDA) Transudate contained in the subarachnoid space.
Definition (NCI) The fluid that is contained within the brain ventricles, the subarachnoid space and the central canal of the spinal cord.
Definition (CSP) clear colorless liquid secreted by the choroid plexus of the lateral, third, and fourth ventricles, and contained within the ventricular system of the brain and spinal cord and within the subarachnoid space.
