Definition

Noun: - A small channel in the brain: The sylvian aqueduct is a narrow, tube-like canal located in the midbrain. It serves as a crucial passageway for cerebrospinal fluid, connecting the third ventricle to the fourth ventricle.

Usage
  • The term is used exclusively in anatomical and neurological contexts to describe this specific structure within the brain's ventricular system.
  • It is often discussed in relation to conditions that can obstruct the flow of cerebrospinal fluid, such as hydrocephalus.
Examples
  • Noun:
    • An obstruction in the sylvian aqueduct can lead to a buildup of cerebrospinal fluid in the brain.
    • The MRI scan clearly showed the pathway of the sylvian aqueduct.
Advanced Usage
  • "Aqueductal stenosis": This is a medical condition referring to a narrowing or blockage of the sylvian aqueduct, which is a common cause of non-communicating hydrocephalus.
    • The infant was diagnosed with hydrocephalus due to aqueductal stenosis.
Variants and Related Words
  • Cerebral aqueduct: This is a direct synonym for the sylvian aqueduct. "Cerebral aqueduct" is the more anatomically precise and commonly used term in modern medical literature.
  • Aqueduct of Sylvius: This is an older, eponymous term (named after the anatomist Franciscus Sylvius) that is synonymous with the sylvian aqueduct.
Synonyms
  • Cerebral aqueduct: The primary synonym.
  • Aqueduct of Sylvius: A historical synonym.
Related Anatomical Terms
  • Ventricle: One of the interconnected cavities in the brain where cerebrospinal fluid is produced and circulates. The sylvian aqueduct connects the third and fourth ventricles.
  • Cerebrospinal fluid (CSF): The clear fluid that flows through the ventricles and around the brain and spinal cord, for which the sylvian aqueduct is a conduit.
Noun
  1. a canal connecting the third and fourth ventricles
