Otic vesicle Otic vesicle Otic vesicle, or auditory vesicle, consists of either of the two sac-like invaginations formed and subsequently closed off during embryonic development. It is part of the neural ectoderm, which will develop into the membranous labyrinth of the inner ear. This labyrinth is a continuous epithelium, giving rise to the vestibular system and auditory components of the inner ear. During the earlier stages of embryogenesis, the otic placode invaginates to produce the otic cup. Thereafter, the otic cup closes off, creating the otic vesicle. Once formed, the otic vesicle will reside next to the neural tube medially, and on
History of anatomy been debunked as a myth by modern historians of science. For many decades human dissection was thought unnecessary when all the knowledge about a human body could be read about from early authors such as Galen. In the 12th century, as universities were being established in Italy, Emperor Frederick II made it mandatory for students of medicine to take courses on human anatomy and surgery. Students who had the opportunity to watch Vesalius in dissection at times had the opportunity to interact with the animal corpse. At the risk of letting their eagerness to participate become a distraction to their
