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 executed, "i.e.", hanged criminals, thus many perceived morbid anatomy for anatomical studies as punishment that is only justified to inflict on the morally condemned. Medical grave robbing incited widespread anger and abhorrence, resulting in at least seventeen full-fledged anatomy riots in the United States between 1785 and 1855, in Connecticut, Vermont, Ohio, and elsewhere. Although a law which outlawed body snatching, and allowed executed criminals to be dissected after death, was passed by the New York legislature after the 1788 riot, medical students continued to face a shortage of cadavers, and so grave robbing persisted These anatomy riots involved citizens
