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
Grotesque body (where the body can be entered). Eating, drinking, burping from excess, etc. is all done through the mouth. Rabelais uses the Carnival to refer to politics and critique the world based on human anatomy. In the Italian celebration of Carnival, masks play a major role as many people wear them during the celebration.
