The image is a diagram illustrating the structure of the cochlea, which is part of the inner ear responsible for hearing. The diagram shows three sections labeled as "Scala Vestibuli," "Scala Tympani," and "Basilar Membrane." These are parts of the cochlear duct.

At the top left corner of the image, there's a small icon representing the oval window where the stapes (a small bone in the middle ear) is located. The diagram also includes labels for other structures such as the "Vestibule," which is at the base of the cochlea and connects to the semicircular canals.

The diagram shows three different sections labeled with "High Frequency," "Middle Frequency," and "Low Frequency." These correspond to where sound waves are detected in the basilar membrane. The high-frequency sounds are detected closer to the oval window, while low-frequency sounds are detected further along the length of the cochlea towards the apex.

The diagram also includes a scale at the bottom that shows the distance along the cochlear duct from "BASE" (where high frequencies are detected) to "APEX" (where low frequencies are detected).

There is text at the top right corner indicating the source of this image: "From Kramer & Brown 'Audiology: Science to Practice'".
