The fluid which surrounds the membranous labyrinth of the internal ear, and separates it from the walls of the chambers in which the labyrinth lies.

The fluid found in the scala, vestibuli and scala tympani.

A fluid similar in composition to cerebrospinal fluid; located in the spaces between the bony labyrinth and the membranous labyrinth of the inner ear.

fluid contained between the bony and membranous labyrinths of the inner ear

the fluid that fills the space between the semicircular canals and vestibule (utricle and saccule) and the surrounding bone.

G. " + L. lympha = clear fluid; a bastard term (from G. & L.) for fluid in bony labyrinth surrounding the membranous labyrinth; cf. endolymph.

watery liquid that fills the outer tubes running through the cochlea.

the bodily fluid that fills the space between the bony labyrinth and the membranous labyrinth of the inner ear

Greek peri = around, and lympha - Latin = clear water; hence, the fluid in the bony labyrinth surrounding the membranous labyrinth (and continuous with the cerebrospinal fluid).

another type of fluid found in the inner ear

A fluid, nearly identical to spinal fluid, that fills the cochlea.

The fluid contained in the space surrounding the membranous labyrinth but within the osseous (bony) labyrinth. This fluid is contiguous with the cerebro-spinal fluid via small openings.

Fluid in scala media of inner ear with composition resembling intracellular fluid.

Perilymph is an extracellular fluid located within the cochlea (part of the ear) in 2 of its 3 compartments; the scala typmani and scala vestibuli. The ionic composition of perilymph is comparable to that of plasma and cerebrospinal fluid. The major cation of perilymph is sodium.
