In gnathostomes, each membranous labyrinth has three semicircular ducts that connect with a chamber known as the utriculus (...); Gnathostome ears have a horizontal semicircular duct. This brings their complement to three semicircular ducts, a pattern retained throughout gnathostome evolution.[well established][VHOG] |
