Oval window
Oval Window
The Oval Window (pronunciation: /ˈoʊvəl ˈwɪndoʊ/) is a crucial part of the human ear anatomy. It is a membrane-covered opening that leads from the middle ear to the vestibule of the inner ear.
Etymology
The term "Oval Window" is derived from its oval shape and its function as a 'window' for transmitting vibrations from the stapes, one of the ossicles, to the inner ear.
Function
The Oval Window is responsible for transmitting sound waves from the middle ear to the inner ear. When the stapes vibrates against the Oval Window, it causes fluid in the inner ear to move, which in turn stimulates sensory cells and initiates the process of hearing.
