摘要: Das Innenohr kann in drei Bereiche unterteilt werden: (1) Cochlea mit Corti-Organ, (2) Gleichgewichtsorgan Bogengangssystem und Crista ampularis sowie (3) Sacculus Utriculus. In allen Bereichen befinden sich Sinneszellen (Haarzellen) Stutzzellen. Die der menschlichen unterteilen ca. 12.000 ausere Haarzellen (AHZ) 3600 innere (IHZ) (Naumann et al. 1994). AHZ sind Reihen die IHZ einer Reihe angeordnet. Sowohl als auch haben Stereozilien. Besonderheit ist, dass sie durch das Motorprotein Prestin kontrahieren bzw. elongieren konnen. Zu den Stutzzellen gehoren Deiters-Zellen, Hensen-Zellen, Pfeilerzellen, Phalangenzellen, Interdental-Zellen Innere Sulkuszellen. spielen fur Regeneration eine bedeutende Rolle.
