What is the function of the aqueduct of Sylvius?
What is the function of the aqueduct of Sylvius?
aka aqueduct of Sylvius. The cerebral aqueduct is a channel that connects the third ventricle with the fourth ventricle and allows cerebrospinal fluid to pass between them.
What does the foramen of Monro do?
The foramen of Monro is a short conduit between the paired lateral ventricles and the third ventricle of the brain. This deep structure becomes clinically significant when obstructed and leads to obstructive (non-communicating) hydrocephalus.
Where is the aqueduct of Sylvius?
midbrain
The cerebral aqueduct (of Sylvius) is the structure within the brainstem that connects the third ventricle to the fourth. It is located within the midbrain, surrounded by periaqueductal grey matter (PAG) with the tectum of midbrain located posteriorly and the tegmentum anteriorly.
Why is it called aqueduct of Sylvius?
The cerebral aqueduct is surrounded by an enclosing area of gray matter called the periaqueductal gray, or central gray. It was first named after Franciscus Sylvius….

Which part of the brain contains the aqueduct of Sylvius?
The midbrain is one of the parts of brainstem that contains the cerebral aqueduct, or aqueduct of Sylvius.
What happens if you block the cerebral aqueduct?
Aqueductal stenosis is a narrowing of the aqueduct of Sylvius which blocks the flow of cerebrospinal fluid (CSF) in the ventricular system. Blockage of the aqueduct can lead to hydrocephalus, specifically as a common cause of congenital and/or obstructive hydrocephalus.

What is brain fluid?
Overview. Hydrocephalus is the buildup of fluid in the cavities (ventricles) deep within the brain. The excess fluid increases the size of the ventricles and puts pressure on the brain. Cerebrospinal fluid normally flows through the ventricles and bathes the brain and spinal column.
What is sylvius?
Sylvius, aqueduct of: A canal between the third and fourth ventricles in the brain within the system of four communicating cavities that are continuous with the central canal of the spinal cord. The ventricles are filled with cerebrospinal fluid, which is carried by the aqueduct of Sylvius.
Which part of the brain contains the aqueduct of Sylvius pons medulla midbrain cerebrum?
Which part of the brain contains the aqueduct of Sylvius? The midbrain is one of the parts of brainstem that contains the cerebral aqueduct, or aqueduct of Sylvius. The pons contains cardiac acceleration and vasoconstriction centers. The cardiac-slowing center and respiratory center are present in the medulla.
