Otic vesicle constricts to form the canalis reuniens. The central part of the otic vesicle represents the membranous vestibule, and is subdivided by a constriction into a smaller ventral part, the saccule, and a larger dorsal and posterior part, the utricle. The dorsal component of the inner ear also consists of what will become the semicircular canals. The utricle and saccule communicate with each other by means of a Y-shaped canal. The FGF, Bmp, Wnt and Pax genes are likely to be involved in otic induction. FGF and BMP signals help control patterning in the early otic vesicle. Fgf3 and Fgf10 are
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
