Semicircular canals
The three semicircular canals per ear are interconnected, fluid-filled tubes that are positioned almost at right angles to each other and belong to the balance organ in the inner ear (vestibular apparatus). They serve to register angular accelerations, i.e., rotational movements of the head.

Round window
The round window is a membrane-covered opening in the cochlea on the middle ear side. It is connected to the scala tympani and enables the necessary pressure equalization in the inner ear when sound is transmitted through the oval window.

Stirrup
The stapes is the third ossicle in the middle ear and the smallest bone in the human body. It transmits its vibrations to the oval window, behind which the inner ear begins.
