A previously unknown hair cell epithelium in the pigeon cochlea: the papilla chaotica.
A previously unknown sensory epithelium can be found on the medial wall of the apical part of the pigeon cochlear duct. It comprises about 200 hair cells. These are not arranged in any regular pattern, shape and orientation of the ciliary bundles even differ in neighbouring hair cells. We therefore propose the term papilla chaotica.
