Figure 4. Structural aberrations of the vestibular aqueduct and endolymphatic sac in mice.
The vestibular aqueduct and endolymphatic sac in the Slc26a4tm1Dontuh/tm1Dontuh mice were enlarged (B & D) compared to those in the Slc26a4+/+ mice (A & C). (1, posterior semicircular canal; 2, superior semicircular canal; 3, subarcuate fossa; 4, fovea for endolymphatic sac (dot-dash line); 5, external orifice of vestibular aqueduct. Bar = 100 µm.
