Fig. 4. Schematic illustrations of the movement of the model cell
(Table 1). Cell motility
variables and abbreviations are given in
Table 1. The cells are viewed
along the YI axis except in G, which is viewed along the
XI axis (see Fig.
2). The position and orientation of the cell is shown at intervals
of 0.25 s, except F, where the time interval is 1 s. The spheres representing
cells are divided into eight regions labelled (from left to right) 1-4 and 5-8
on the upper and lower hemispheres, respectively. Arrows indicate the swimming
trajectory and direction of turning. (A) LF+h2TF, (B) LF+h9TF, (C) LF+Stf, (D)
h2TF, (E) h9TF, (F) Stf, (G) LF.
