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 set up to teach people the natural and moral sciences of the human body, anatomy museums gradually declined in status with the progress of medical science and education. In postbellum America, the division between high and low medicine increased. The focus of public scientific education turned toward the structures and functions of plants, animals, and cells, and this was done through politically and socially approved public school curriculums and sanitary fairs. These other avenues not only appeared more legitimate, but also reduced the uniqueness of anatomy museums. Anatomy museums' popularity also suffered with the establishment of nonprofit art and natural
