WebCanal neuromasts, numbering in Fig. 1 starting from the snout, are situated on the bottom of subcutaneous canals. The hairs of the hair cells in a neuromast protrude into the cupula, a moving structure that covers the hair cells and couples the motion of the canal fluid to the motion of the hair bundles. WebThe neuromast is composed of receptor cells, supporting cells and mantle cells. The receptor cells bear one kinocilium and up to 40 stereocilia. Bi-directional arrangement of the receptor cells as occurs in teleosts was demonstrated. Afferent and efferent nerve endings were found at the base of the receptor cells.
