What does the ambient cistern do?

What does the ambient cistern do?

The ambient cistern is a thin, sheet-like extension of the quadrigeminal cistern that extends laterally around the midbrain and posterior to the thalami. It acts as the connection between the quadrigeminal cistern and the interpeduncular cistern.

What is interpeduncular cistern?

The interpeduncular cistern (or basal cistern) is an unpaired CSF-filled subarachnoid cistern located between the cerebral peduncles. It is partially bounded by the leaves of the Liliequist membrane, one of the arachnoid membranes, which separate it from its direct cranial and caudal relations1.

What is a cistern neuroanatomy?

Cisterns are openings in the subarachnoid space of the brain created by a separation of the arachnoid and Pia mater. There are many cisterns in the brain, but the notable ones include: Lies behind the medulla and below the cerebellar hemispheres.

Where is the interpeduncular cistern located in the brain?

The interpeduncular cistern is located between the cerebral peduncles (connects the remainder of the brain stem to the brain’s thalamus)(16). This cistern is known to eminently communicate with the chiasmatic cistern and abjectly communicate with the pontine cistern(17).

Where is the interpeduncular fossa located in the brain?

Nicholas Vargas and Dr Jeremy Jones ◉ et al. The interpeduncular cistern (or basal cistern) is one of the subarachnoid cisterns. It is a wide CSF- filled cavity between the two temporal lobes anteriorly and encloses the cerebral peduncles as well as structures contained within the interpeduncular fossa.

How is CT used to diagnose cerebral cisterns?

A study used computed tomography (CT) to evaluate subarachnoid spaces and cisterns in teenagers and children. The CT examination images showed linear indices that can be calculated to identify the typical subarachnoid spaces’ sizes within the specific age group(26).

Is the sylvian fissure anterior to the interpeduncular cistern?

The suprasellar cistern is anterior to the interpeduncular cistern and usually has a five-point or six-point starlike appearance. The sylvian fissures are bilaterally symmetrical and contain CSF. They separate the temporal from the frontal and parietal lobes.
