Summary of the differences in cilia structures between the medial region and the tip
| Region Structure . | Medial region . | Tip region . |
|---|---|---|
| Doublets | Intact Linked to each other by the N-DRC complex | B-tubules are absent Inner junction is incompletely assembled |
| A-tubules | Present as part of the doublet | Singlets Parallel to each other Linked to each other Linked to the membrane Have different lengths |
| Central pair | Big projections on both microtubules | The two microtubules are closer to each other The projections disappear and are replaced by small projections |
| Capping structures | None | A-tubules and CP microtubules are capped by filamentous structures |
