Claudius cell

Claudius cells are considered as supporting cells within the organ of Corti in the cochlea. These cells extend from Hensen's cells to the spiral prominence epithelium, forming the outer sulcus. They are in direct contact with the endolymph of the cochlear duct. These cells are sealed via tight junctions that prevent flow of endolymph between them. Boettcher cells are located immediately under Claudius cells{{Cite journal|last1=Kanazawa|first1=A.|last2=Sunami|first2=K.|last3=Takayama|first3=M.|last4= Nishiura|first4=H.|last5=Tokuhara|first5=Y.|last6=Sakamoto|first6=H.|last7=Iguchi|first7=H.|last8=Yamane|first8=H.|title=Probable function of Boettcher cells based on results of morphological study: localization of nitric oxide synthase.|journal=Acta Otolaryngol Suppl|issue=554|pages= 12–6|date=Oct 2004|doi=10.1080/03655230410018444|PMID=15513504}} in the lower turn of the cochlea.{{cite book|last1=Jahn|first1=AF.|last2=Santos-Sacchi|first2=J.|title=Physiology of the ear|url=https://books.google.com/books?id=giFuKH5u7O0C&pg=PA274|accessdate=26 May 2011|date=8 February 2001|publisher=Cengage Learning|isbn=978-1-56593-994-3|pages=274}}
