It frequently appears near mucus-secreting goblet cells. Cilia are tiny hair-like protuberances on the exterior of eukaryotic cells (or cilia in plural). WebStephen M. King, in Dyneins: Structure, Biology and Disease (Second Edition), 2024 Abstract. Axonemal dyneins form the inner and outer arms that are associated with doublet microtubules within cilia and flagella. These enzymes provide the motive force necessary for ciliary/flagellar beating by driving the sliding of microtubules with respect to each other.
