AQUEDUCTUS CEREBRI Meaning and
Definition
-
Aqueductus Cerebri, commonly known as the cerebral aqueduct, is a narrow canal in the brain that serves as a pathway for cerebrospinal fluid (CSF) to circulate between different regions of the central nervous system. Specifically, it connects the third and fourth ventricles of the brain, allowing for the continuous flow of CSF.
The aqueduct is located within the midbrain, a region that lies between the diencephalon (thalamus and hypothalamus) and the pons. It is surrounded by surrounding neural tissue and comprises a small tunnel-like structure. The aqueduct is lined with ependymal cells, a specialized type of epithelial cells that produce and help circulate CSF.
The main function of the aqueductus cerebri is to facilitate the movement of CSF from the lateral ventricles to the fourth ventricle, aiding in the maintenance of normal intracranial pressure and the exchange of important nutrients, electrolytes, and waste products throughout the brain. Additionally, the aqueduct also plays a crucial role in the regulation of moisture and pressure within the central nervous system.
Obstruction or stenosis of the aqueductus cerebri can lead to a condition known as aqueductal stenosis or hydrocephalus, characterized by the abnormal accumulation of CSF within the ventricles. This condition can cause increased pressure on the brain, leading to various neurological symptoms, such as headache, nausea, vomiting, and changes in cognition or behavior. Treatment for aqueductal stenosis usually involves surgical intervention to relieve the blockage and restore normal CSF flow.

Etymology of AQUEDUCTUS CEREBRI
The term "Aqueductus Cerebri" is derived from Latin.
- "Aqueductus" is the Latin word for "aqueduct". It is a noun formed from the combination of "aqua" meaning "water" and "ductus" meaning "leading" or "conduit". In this context, it refers to a canal or passageway that carries fluid.
- "Cerebri" is the genitive form of "cerebrum", the Latin word for "brain". It is a noun referring to the organ in the head that controls the central nervous system and functions as the center of thought, emotion, and coordination.
When combined, "Aqueductus Cerebri" translates to "aqueduct of the brain" or "the brain's aqueduct".
