Supporting cells in the organ of corti
WebJun 22, 2024 · The organ of Corti comprises two types of mechanosensory hair cells (inner and outer hair cells; IHCs and OHCs) and at least six types of associated non-sensory supporting cells (SCs), arranged in rows to form a highly ordered asymmetric mosaic extending along the basal-to-apical (tonotopic) axis of the cochlea . Although the overall … WebOct 1, 2002 · The term ‘scar’ is used to describe replacement of the original cell type (hair cell) by a ‘filling’ cell, a supporting cell. The use of the term scar in the organ of Corti is justified because the scar is permanent. The immediate role of the scarring process is to prevent fluid mixing.
