Verified by Experts

Ciliary locomotion is fastest swimming movement of protozoans, Hence, ciliates are the fastest protozoans.
Cilia are small hair-like structures found in ciliate protozoans like Paramecium.
Infraciliary system : It is located just below the pellicle in the ectoplasm of a ciliate. It includes kinetosomes, kinetodesmal fibrils and kinetodesmata. The kinetosomes are present at the bases of cilia in transverse and longitudinal rows. The kinetodesmal fibrils are connected to the kinetosomes and run along the right side of each row of kinetosomes as a .cord of fibres. called kinetodesmata. A longitudinal row of kinetosomes together with kinetodesmata .constitute a unit called kinety.
All the kineties together form an infraciliary system, which is connected to a .motorium., located near the cytopharynx. The infraciliary system and motorium form the .neuromotor system that controls and coordinates the movement of cilia.
