U01.01.029 Cilia structure

Analyze the clinical clues carefully — recurrent sinus infections, bronchiectasis, and infertility — which point toward a ciliary motility disorder. Then, use the microscopic finding of absent dynein arms to determine which microtubule arrangement or structural defect best explains the pathology. Match these features with the correct ultrastructural pattern of cilia.
