Figure 11. Muscles in protopod and exopod of thoracopod 1 (Thp1; right) of Lophogaster typicus (male); micro-computed tomography volume rendering. A, C, white lines emphasize the margin of the thorax and the outlines of the basis and the epipodal sclerites. A, anterior view. B, macerated sample; anterior view of coxa–epipod articulation; colour code of podomeres as in Figure 1. C, posterior view; dashed line indicates continuation of the thoracic margin in the background. Abbreviations: Ba, basis; Co, coxa; dis, distal; Ep, epipod; Ex, exopod; lat, lateral; S1, dorsal sclerite of epipod; S2, ventral sclerite of epipod; Th, thorax. Numbered muscle labels are as in Table 4.
