These structures name a cell type marked by FOXJ1 (“fox-J-one”), which is required for these structures’ biogenesis. In the absence of one ligand, GLI3 (“glee-three”) is cleaved into a repressor due to the enrichment of Smoothened (-5[1])in these structures. The opening of (-5[1])MET (15[1])channels unleashes a calcium cascade after a “kino” (15[1])(“KYE-no”) one of these structures (15[1])is pushed (-5[1])over during sound transduction. (15[1])Wnt (15[1]-5[1])(“wint”) and (*) Hedgehog (10[1])signaling (10[1]-5[1])components (-5[1])are localized (-5[1])from the transitional zone to these structures by IFT particles. (-5[2])“Primary” types of these structures (10[1])lack the inner doublets of the (-5[1])9+2 (-5[1])(“nine-plus-two”) axoneme (-5[2])found (-5[1])in a related (-5[1])type of these (-5[1])structures. An eponymous “clearance” (-5[1])that removes mucus from the respiratory tract (-5[1])is powered by these structures’ (10[1])synchronized “beating.” (10[7])For (10[1]-5[1])10 points, name these hairlike (-5[1])microtubular (10[8])appendages (-5[1])contrasted (10[2])with flagella.
