DPhaFIG 5: Shape and musculature of dauer anterior metacorpus.

A. Illustration of pharynx with arrow showing approximate position of transverse TEM sections in B&C. (Image source: WormAtlas PhaFIG 2A.)
B. Transverse TEM sections of L2 larva anterior metacorpus. Features of metacorpus are as follows: mc, marginal cell; nc-d, dorsal nerve cord; nc-svl, left subventral nerve cord; nc-svr, right subventral nerve cord. (Image source: N2 L2 28-14 [D. Riddle] 750.)
C. Transverse TEM section of dauer anterior metacorpus. Arrowheads indicate muscle fibers for comparison in L2 and dauer images. Note heterogeneity in cross-sectional shape of dauer pharynx. Images are not presented at the same scale, and were differentially magnified to show structural features. (Image source: N2 starved dauer 50-2-2 [D. Riddle] 462M.)
