Two views of the topography of the chorda tympani in combination with the malleus and the tensor tympani muscle and tendon (gerbil 2). The soft tissue data originate from OPFOS (voxel size is 2 × 2 × 4.5 μm), while the malleus data come from μCT (voxel size is 8.5 × 8.5 × 8.5 μm). b bulla, c chorda tympani, m muscle, o malleus ossicle, t tendon, l manubrium length.
