Fig. 3. Electron micrographs of mechanosensory neuron and pharyngeal defects in fibulin-1 (hd43) mutants. ALM mechanosensory neuron attachment in wild-type (A) and mutant (B) hermaphrodites. Arrows indicate position of axon; arrowheads indicate extracellular mantle. Also shown is the dorsal body-wall muscle (mus). (C,D) Electron micrographs of cross-sections through the pharynx of wild-type (C) and fbl-1(hd43) mutant (D) animals. Arrows indicate pharyngeal basement membranes that are distorted in mutant animals. Scale bars: 0.5 µm in A,B; 2 µm in C,D.
