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 other mammals, not human bodies. Andreas Vesalius, born and educated in Belgium, contributed the most to human anatomy. Vesalius's success was due in large part to him exercising the skills of mindful dissections for the sake of understanding anatomy, much to the tune of Galen's "anatomy project" instead of focusing on the work of other scholars of the time in recovering the ancient texts of Hippocrates, Galen and others (which much of the medical community was focused around at the time).Vesalius was the first to publish a treatise, "De humani corporis fabrica", that challenged Galen "drawing for drawing". These drawings
