Endolymph

Endolymph (/ɛndoʊˌlɪmf/; from Greek endo meaning "inside" and lymph meaning "water") is a fluid found in the inner ear of mammals. It is one of the two major fluids in the inner ear, the other being perilymph.

Function

Endolymph is crucial for the normal function of the inner ear. It fills both the cochlea, where it plays a key role in transmitting sound vibrations to the brain, and the vestibular system, where it helps maintain balance.

Composition

Endolymph is unique in its composition compared to other bodily fluids. It is high in potassium and low in sodium, which is essential for the proper functioning of the hair cells in the inner ear that detect sound vibrations and head movements.

Disorders

Disorders of the endolymph, such as Meniere's disease, can lead to symptoms like vertigo, tinnitus, and hearing loss. These disorders are often treated with medications, diet changes, or in severe cases, surgery.
