ENDOLYMPHATIC SAC Meaning and
Definition
-
The endolymphatic sac is a small, membranous structure located in the inner ear, specifically in the vestibular system. It serves as a crucial component of the auditory and vestibular systems, playing a role in maintaining the fluid balance and pressure within the inner ear.
This sac is responsible for the production, absorption, and regulation of endolymph, a unique fluid found in the inner ear. Endolymph helps transmit sound signals and facilitates the detection of head movements and body balance. It is essential for the normal functioning of the cochlea, which is responsible for converting sound vibrations into electrical signals that are interpreted by the brain.
The endolymphatic sac consists of a sac-like structure containing a network of tiny blood vessels and cells that actively regulate the composition and volume of the endolymph fluid. It acts as a reservoir, where excess endolymph can be absorbed or stored to maintain optimal fluid pressure. By controlling the ion concentration and hydrostatic pressure in the inner ear, the endolymphatic sac ensures proper functioning of the auditory and vestibular systems.
Disorders or dysfunctions of the endolymphatic sac, such as endolymphatic hydrops, can lead to imbalances in fluid pressure, resulting in symptoms like vertigo, dizziness, tinnitus, and hearing loss. Surgical interventions like endolymphatic sac decompression or shunt placement may be required to alleviate the symptoms and restore normal fluid regulation.

Etymology of ENDOLYMPHATIC SAC
The word "endolymphatic" originates from the combination of two Latin words: "endo" meaning "within" or "inside", and "lympha" meaning "clear fluid" or "water". Meanwhile, "sac" comes from the Latin word "saccus", referring to a bag or pouch. Therefore, the term "endolymphatic sac" is derived from Latin roots and describes a sac-like structure situated within the ear that contains clear fluid or endolymph.
