Otic vesicle chick, invagination of the otic placode occurs passively due to the movements of the surrounding placode. The otic placode in zebrafish, on the other hand, occurs by cavitation; the ectodermal placode condenses and forms an ovoid ball directly below the embryo surface. Otic vesicle formation occurs later, during the 25-30 somite stage in mice. 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
Anatomy for Beginners Anatomy for Beginners Anatomy for Beginners is a television show created by Gunther von Hagens. In this 4-part series, Dr von Hagens and Professor John Lee demonstrated the anatomical structure and workings of the body. The 4 episodes ("Movement", "Circulation", "Digestion" and "Reproduction") were screened in the United Kingdom on Channel 4 in 2005. The show features public anatomy demonstrations with the use of real human cadavers and live nude models (for Surface Anatomy and Surface Markings), carried out at Gunther von Hagens' "Institute for Plastination" in Heidelberg, Germany. Dr von Hagens’ public demonstrations are not formal anatomy dissections performed
