Musculature and innervation of enlarged papillae. a. Musculature and innervation revealed by anti-acetylated α-tubulin antibody. b. Body wall adjacent to the enlarged papilla. c-f. The organization of SP-lir (green) and 5HT-lir (red) innervation of enlarged papillae. Cell nuclei (blue) on c are counterstained by DAPI. e. The tip of papilla at higher magnification. Note the nerves underlying the cuticular plate. g-i. Separated fluorescent channels showing acetylated α-tubulin (g), 5-HT (h), and. SP-lir (i) nerve elements of the same papilla. Abbreviations: cp – cuticular plate, fne – free nerve endings, m – musculature of the papilla. Muscles – yellow (phalloidin staining), acetylated α-tubulin-lir – magenta, 5HT-lir – red, Substance P-lir – green
