semicircular canals (of bony labyrinth)

[TA]
the organ of balance; the three bony tubes of the labyrinth of the inner ear within which the membranous semicircular ducts are located; they lie in planes at right angles to each other and are known as anterior semicircular canal [TA] (canalis semicircularis anterioris [TA]), posterior semicircular canal [TA] (canalis semicircularis posterioris [TA]), and lateral semicircular canal [TA] (canalis semicircularis lateralis [TA]).

In the control group, there were no significant differences between left and right ears in terms of VOR gains, and the average VOR gains for PSCC, anterior semicircular canal (ASCC), and LSCC were 0.96[+ or -]0.14, 0.96[+ or -]0.13, and 0.99[+ or -]0.09, respectively, for a total of 40 ears.
