Valvula vestibuli is a Latin term used in anatomy to refer to a structure of the ear. Specifically, it translates to "vestibular valve" in English. The valvula vestibuli is a component of the inner ear, located within the bony labyrinth. It is a crescent-shaped membranous structure that separates the cochlea, the spiral-shaped cavity responsible for hearing, from the vestibule, which plays a role in maintaining balance and spatial orientation.
The function of the valvula vestibuli is to cover and protect the entrance to the cochlea, acting like a valve. It acts as a barrier that prevents the free communication between the cochlea and the vestibule. This valve-like structure helps regulate the exchange of fluid and pressure between the cochlea and the vestibule, ensuring the optimal functioning of both compartments.
The valvula vestibuli is composed of a delicate membrane that is part of the membranous labyrinth. It is surrounded by fluid called perilymph, which also fills the surrounding spaces of the inner ear. This fluid provides the necessary support and cushioning for the sensitive structures involved in hearing and balance.
In summary, the valvula vestibuli is a membranous structure in the inner ear that separates the cochlea from the vestibule. Its role is to act as a valve, regulating the exchange of fluid and pressure between these two compartments, thereby contributing to the proper functioning of both hearing and balance.

The word "valvula vestibuli" is Latin in origin.
- "Valvula" comes from the Latin word "valva", which means 'a folding door' or 'a valve.' It is derived from the verb "volvere", which means 'to roll' or 'to turn.'
- "Vestibuli" is the genitive form of the Latin word "vestibulum", which means 'entrance' or 'vestibule.' It is derived from the verb "vestire", which means 'to clothe' or 'to cover.'
Combined, "valvula vestibuli" translates to 'valve of the vestibule' in English. This term is used in anatomy to refer to a small, membranous structure in the inner ear.
