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 in the 19th century horror of being the subject of dissection. The criminal temptations ultimately led to the 1827–1828 West Port murders in Edinburgh, UK, where likely candidates were killed and sold for cash. The murders led to the passing of the Anatomy Act 1832 which finally provided for an adequate and legitimate supply of corpses. History of anatomy in the 19th century The history of anatomy in the 19th century saw anatomists largely finalise and systematise the descriptive human anatomy of the previous century. The discipline also progressed to establish growing sources of knowledge in histology and developmental biology, not only of humans
