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 by medical students in some countries as part of their medical training. Formal dissection are performed slowly and take dozens of hours of dissection. "Anatomy for Beginners" performs quicker autopsy and also combines with demonstration of plastinated body parts and specimens to gives just a glimpse of the human anatomy. The individuals on whom the demonstration was performed had, before their death, enrolled on von Hagens’ body donor programme and consented to the use of their bodies for public education in anatomy, including public demonstration. Anatomy for Beginners Anatomy for Beginners is a television show created by Gunther von Hagens.
