Interpeduncular Cistern

The interpeduncular cistern (basal cistern or Fossa interpeduncularis) is a wide cavity where the arachnoid extends across between the two temporal lobes.

It encloses the cerebral peduncles and the structures contained in the interpeduncular fossa, and contains the arterial circle of Willis.

Famous quotes containing the word cistern:

    “But there, where I have garnered up my heart,
    Where either I must live or bear no life;
    The fountain from the which my current runs
    Or else dries up: to be discarded thence,
    Or keep it as a cistern for foul toads
    To knot and gender in!”
    —William Shakespeare (1564–1616)
