AHypFIG 5: Localized deterioration of hypodermal structure beneath body muscle attachment regions.
A-C. Transverse images in the anterior midbody of a day 7 adult which was scored as "highly mobile" (Herndon et al., 2002).
A. Color-coded image indicating the major internal structures: intestine (pink), body muscle (green), hypodermis (tan), excretory cell (magenta), neurons (dark red).
B&C. Enlargements of boxed areas showing the hypodermis in the region where it underlies the basal lamina and body muscle. Asterisks indicate areas where the hypodermis appears to be thinning, possibly indicating age-related deterioration. Arrowheads indicate intact intermediate filaments which bind the body muscle to the cuticle through the basal lamina and hypodermis.
