MEMBRANOUS LABYRINTH Meaning and
Definition
-
The term "membranous labyrinth" refers to a complex structure found within the inner ear, which is responsible for transmitting sound waves and converting them into electrical signals that can be interpreted by the brain. It consists of a series of delicate, fluid-filled sacs and ducts that are encased within the bony labyrinth.
The membranous labyrinth is divided into several interconnected components, each serving a specific function. These include the cochlea, which is responsible for hearing, and the vestibular system, which is responsible for balance and spatial orientation. These components are filled with a fluid called endolymph, which helps to transmit sound vibrations and detect changes in head position and movement.
Within the membranous labyrinth, there are specialized sensory cells known as hair cells. These hair cells are equipped with tiny hair-like projections called stereocilia, which are responsible for converting mechanical vibrations into electrical signals. When sound waves or changes in head position occur, the movement of the fluid within the membranous labyrinth causes the stereocilia to bend, initiating the transmission of electrical signals to the auditory nerve or vestibular nerve.
Overall, the membranous labyrinth plays a vital role in our sense of hearing and balance, helping us perceive the world around us and maintain our equilibrium.

Etymology of MEMBRANOUS LABYRINTH
The word "membranous labyrinth" has a compound etymology.
The term "labyrinth" comes from the Greek word "labýrinthos", which referred to a complex maze-like structure. It is believed to have its origins in the Minoan civilization on the island of Crete, where intricate, maze-like structures were constructed. The word "labyrinth" later entered the Latin language as "labyrinthus" and eventually made its way into English.
The word "membranous" comes from the Latin word "membrana", which means "membrane". It refers to a thin, pliable sheet-like structure, often used to describe flexible coverings that exist in living organisms.
When combined, "membranous labyrinth" refers to the delicate, membranous structures within the inner ear that are responsible for hearing and balance.
