Weberian apparatus

From Wikipedia, the free encyclopedia

The Weberian apparatus is made up of a set of bones known as Weberian ossicles, a chain of small bones that connect the auditory system to the gas bladder of fishes. It is a characteristic of the superorder Ostariophysi. The ossicles connect the pulsating gas bladder wall with Y-shaped lymph sinus that abuts the lymph-filled transverse canal joining the sacculi of the right and left ears. This allows the transmission of vibrations to the inner ear of some fish. It is named after the German anatomist and physiologist Ernst Heinrich Weber (1795 – 1878).
