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
Sociopolitical issues of anatomy in America in the 19th century US similarly sought to set the medical profession apart from alternative medicine and other rivals through increased anatomical studies. As a result, the demand for corpses by medical students for dissection studies grew, which in turn propelled widespread medical grave-robbing, social strife and legislative changes to provide anatomists with legal supplies of cadavers. Medical grave robbery prompted anatomy riots in nearly every medical institution and drove changes in legislatures. The increase in importance of anatomy in medical studies also increased society's interest in the human body, which prompted the popularization of anatomy museums. The societal funerary obligation to respect the
