kinetosome
Quick Summary
In biology, a kinetosome is another term for a basal body. A basal body is a small organelle found at the base of a flagellum or cilium, and it is structurally identical to a centriole. These structures are crucial for the movement of many protists, which use flagella or cilia to propel themselves through their environment.123
While the kinetosome (basal body) is involved in the structure and function of flagella and cilia, it is distinct from a kinetoplast. A kinetoplast is a DNA-containing organelle found within the mitochondrion of certain organisms, such as trypanosomes, and is located near the basal body.4

The anchorage provided by the basal body is strengthened by musclelike fibres and special microtubules called microtubular roots. Most flagellate cells have two flagella, and therefore two basal bodies, each with microtubular roots. The orientation of…
