FIG 1.

Diagram of the flagellum and surrounding structures in BF T. brucei. The image on the bottom is a scanning electron micrograph of a BF trypanosome. The section in the dashed box, representing the base of the flagellum and the surrounding cellular components, has been expanded as a schematic diagram at the top of the figure. Subcellular structures associated with the flagellum are indicated by labeling. PFR indicates the paraflagellar rod and FAZ the flagellum attachment zone.
