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 been made, but are generally unsupported. The most common, wine, had its own battery of containers from serving and drinking ware (cups, mixers, bowls, etc.) to transport vessels, the amphorae, which are generally larger and more plentiful than stirrup-jars. Wine was apparently more plentiful. Oil requires a significant investment in olive trees, which cannot be harvested for several years after planting. A third suggestion, perfume, is not compatible with the small quantities placed in perfume jars, which are always very small. The relatively large stirrup jars would represent unrealistically huge amounts of perfume. The early stirrup-jars were not distinguished by
