MEMBRANA BASILARIS Meaning and
Definition
-
The membrana basilaris refers to a key structure within the human auditory system, specifically located in the cochlea of the inner ear. It plays a crucial role in the process of hearing and is responsible for converting sound waves into electrical signals that can be interpreted by the brain.
The membrana basilaris is a thin, flexible membrane that stretches longitudinally along the cochlea. It separates the scala tympani and the scala media, two compartments filled with fluid. The apex of the cochlea, where the membrane is wider and more flexible, is sensitive to low-frequency sound waves, while the base of the cochlea, where the membrane is narrower and stiffer, responds to high-frequency sounds.
Within the membrana basilaris resides the organ of Corti, a complex structure composed of sensory hair cells that are vital for auditory perception. These hair cells are embedded in the tectorial membrane, which overlaps the membrana basilaris. When sound vibrations enter the cochlea and propagate through the fluid-filled scala tympani, they cause the basilar membrane to vibrate, leading to the displacement of the hair cells and the generation of electrical signals that are transmitted to the brain via the auditory nerve.
In summary, the membrana basilaris is a delicate membrane inside the cochlea that, together with the organ of Corti, is essential for hearing by converting sound vibrations into electrical signals.

A membrane extending from the lamina spiralis ossea to the crista basilaris of the cochlea, forming the greater part of the floor of the ductus cochlearis, or scala media, and supporting the organ of Corti.

Etymology of MEMBRANA BASILARIS
The word "membrana basilaris" has its etymology rooted in Latin and Greek.
The term "membrana" comes from the Latin word membrāna, which means "membrane" or "thin layer". In anatomy, "membrana" is commonly used to refer to a thin layer of tissue that separates or lines structures within the body.
The word "basilaris" comes from the Latin word basilaris, which is derived from the Latin word basis, meaning "base" or "foundation". In anatomy, "basilaris" refers to structures that are located at the base or bottom part of a particular organ or body part.
In combination, "membrana basilaris" refers to the basilar membrane, which is a thin layer of tissue found in the cochlea of the inner ear.
