The Influence of Duct and Utricular Morphology on Semicircular Canal Response

  • Charles M. Oman


Recently a renewed interest has developed in the question of what constitutes the physiologic magnitude and bending mode of motion of the semicircular canal cupula. In 1972, Oman and Young (26) theoretically estimated that, regardless of bending mode, the motion of the middle of thehuman cupula ought to be limited to about 3 μm for maximal self-induced sinusoidal head motion. Experimental investigations of cupula motion in the frog ( 10,21,22) and in the skate (7,24,25) have supported the notion that the relatively large “swinging door” rotation described by early workers is likely artifactual, and have suggested that in the frog (and possibly also in the skate) the cupula is normally adherent not only to the crista, but also to the vault of the ampulla, and deforms as a diaphragm.
