Cochlea to structures in the brainstem for further processing. The "stapes" (stirrup) ossicle bone of the middle ear transmits vibrations to the "fenestra ovalis" (oval window) on the outside of the cochlea, which vibrates the perilymph in the "vestibular duct" (upper chamber of the cochlea). The ossicles are essential for efficient coupling of sound waves into the cochlea, since the cochlea environment is a fluid–membrane system, and it takes more pressure to move sound through fluid–membrane waves than it does through air; a pressure increase is achieved by the area ratio of the tympanic membrane to the oval window, resulting in
Stirrup jar jar offers two basic zones for decoration, the body and the shoulder. These are defined by concentric bands of color around the bottom and the top of the vase. The bands are present on nearly every stirrup jar, whether the canvases are painted or not. Sometimes the bands cover the entire body, and are the only decoration. The colors, generally red or brown on a cream or buff slip, are produced by hematitic inclusions in the paint. Evidence of the Linear B documents indicates that Stirrup jars were used as containers for olive oil. Speculations as to other content have
