Fig. 2. Trypanosome cell architecture. A simplified representation of the location of the major structural features of the trypanosome cell. A cutaway section towards the anterior of the cell shows the microtubule cytoskeleton underlying the cell membrane. For more-detailed images of the trypanosome cell, the reader is referred to recent articles (Grunfelder et al., 2003; Overath and Engstler, 2004; Vaughan and Gull, 2003).
