PERILYMPHATIC DUCT Meaning and
Definition
-
The perilymphatic duct refers to a small canal or vessel that connects the scala tympani of the cochlea in the inner ear with the subarachnoid space of the brain. It is a crucial component of the lymphatic system within the ear.
Within the inner ear, there are two fluid-filled compartments called scala vestibuli and scala tympani. These compartments are separated by the cochlear duct, which contains the organ of Corti responsible for hearing. The perilymphatic duct acts as a fluid-filled conduit, allowing the perilymph fluid to flow between the scala tympani and the subarachnoid space.
The perilymphatic duct aids in maintaining the delicate balance of fluid pressure within the inner ear. It regulates the distribution of perilymph, ensuring that the fluid is correctly circulating and maintaining optimal conditions for the cochlear structures to function.
This duct is also significant for its role in the clearance of waste products and the removal of excess fluid from the cochlea. It allows the perilymph to exit the inner ear and be absorbed into the subarachnoid space, where it can be processed and eliminated.
In summary, the perilymphatic duct is a narrow channel that connects the cochlea to the subarachnoid space, providing a pathway for the circulation and removal of perilymph fluid within the inner ear.

Etymology of PERILYMPHATIC DUCT
The term "Perilymphatic Duct" is a combination of two words: "perilymph" and "duct".
The word "perilymph" comes from the Greek words "peri" meaning "around" and "lympha" meaning "clear fluid". Perilymph refers to the clear fluid that fills the space surrounding the membranous labyrinth in the inner ear.
The word "duct" is derived from the Latin word "ductus", which means "to lead or convey". In anatomy, a duct refers to a tubular structure that carries fluid within the body.
Therefore, the etymology of "Perilymphatic Duct" can be understood as a tubular structure (duct) that carries the perilymph (clear fluid) within the body.
