Medical Definition of Semicircular ducts

1. Three membranous semicircular tubes contained in the bony labyrinth of the inner ear. They are concerned with equilibrium and the interpretation of the bodys position in space. The three canals are set anterior, posterior, and lateral, at right angles to each other and are situated superior and posterior to the vestibule. Each canal opens into the vestibule through five openings of which one is common to the anterior and lateral ducts. Each duct has an ampulla at one end within which filaments of the vestibular nerve terminate. Synonym: ductus semicirculares. (12 Mar 2007)
