Fig. 7. Movements of the coxo-trochanteral joint of Aphrodes. (A–C) Ventral views of the joint if the left hind leg is forcibly moved (blue arrows) into different positions from fully levated (A) to almost fully depressed (C). The right hind leg remains in the same partially depressed position throughout. Scale bar, 200 µm. (D) The lever arms of the trochanteral depressor and levator muscles plotted over the full range of coxo-trochanteral movements.
