OVAL WINDOWS Meaning and
Definition
-
Oval windows, also known as ovals of the organ of Corti, refer to two specialized small openings found in the bony structure, specifically in the cochlea of the inner ear. These windows play a crucial role in transmitting sound vibrations and enabling hearing in humans and other mammals.
The oval windows are composed of thin, membrane-like tissues that approximate the shape of an oval. They are situated adjacent to the middle ear cavity and are surrounded by the temporal bone. As sound waves enter through the ear canal, they cause the tympanic membrane (eardrum) to vibrate. These vibrations are then transferred to the three middle ear ossicles, specifically the malleus, incus, and stapes. The stapes bone, which is connected to the ossicles, moves back and forth in response to these vibrations and ultimately causes the oval windows to move in a piston-like manner.
This movement of the oval windows generates an amplified pressure wave within the fluid-filled cochlea, a spiral-shaped structure responsible for converting sound vibrations into electrical signals that can be sent to the brain. The opening of the oval windows allows the fluid within the cochlea to respond to these waves, stimulating the sensory hair cells and transmitting the auditory signals to the auditory nerve.
In summary, the oval windows serve as the interface between the middle ear and inner ear, converting airborne sound vibrations into fluidic pressure waves to facilitate the process of hearing.
