Figure 12.

Three-dimensional images of an immersion fixed, otic capsule intact cochlea viewed at a wavelength of 488 nm to enhance formaldehyde autofluorescence. This specimen was not immunostained. Viewed from lateral (a), apical (b) and after rotation to the round window (c) perspectives, then changing the depth of view to just inside the round window (d). Not only is the vasculature depicted in great detail, but also the spatial relationships that exist between vascular elements and internal structures such as hair cells (HC), the spiral ganglia (SGC) and auditory nerve (AN). Scale in a same for all images. cv, collecting venules; OW, oval window; ra, radiating arterioles; RW, round window; sma, spiral modiolar artery; SGC, spiral ganglion cells; st a, stapedial artery; sv, stria vascularis.
