| the epithelia of the protrusible tongue of eurycea longicauda guttolineata (hoolbrook 1838) (urodela: plethodontidae). | in this study the lingual and sublingual glands, the lingual stem and the epithelial surface of the protrusible secondary tongue were investigated by light, scanning and transmission electron microscopy. the quality of the secretions of the epithelia was characterized histochemically. the lingual epithelium is formed by superficial (pavement) and goblet cells and at the margin of the tongue pad are also regions covered by ciliated cells. on the dorsal part of the tongue there are goblet cells of ... | 2003 | 15121544 |
| spermatogenic cycle of a plethodontid salamander, eurycea longicauda (amphibia, urodela). | previous investigators have described the spermatogenic cycles of numerous species of plethodontid salamanders. most studies describe a fairly stereotypical cycle with meiotic divisions of spermatogenesis commencing in the spring/summer. however, many studies lack details obtainable from histological examination and/or testicular squashes and, instead, provide only mensural data from the testes. studies that lacked microscopic evaluation often revealed spermatogenic cycles that varied greatly fr ... | 2017 | 26413402 |

| modification of genital kidney nephrons for sperm transport in a plethodontid salamander, eurycea longicauda. | salamanders possess kidneys with two distinct regions: a caudal pelvic portion and cranial genital portion. nephrons of the pelvic region are responsible for urine formation and transport. nephrons of the genital region transport sperm from testes to wolffian ducts; however, nephrons of the genital region possess all the same functional regions found in pelvic kidney nephrons that are involved with urine formation and transport (renal corpuscles, proximal tubules, distal tubules, and collecting ... | 2019 | 31313860 |
| batrachochytrium dendrobatidis in a captive collection of green salamanders ( aneides aeneus), long-tailed salamanders ( eurycea longicauda), and two-lined salamanders ( eurycea bislineata). | a chytridiomycosis outbreak from batrachochytrium dendrobatidis ( bd) in a mixed-species plethodontid salamander exhibit resulted in four green salamander ( aneides aeneus) deaths. one green salamander died before treatment, and three died during treatment with daily 0.005% itraconazole baths. all salamanders had evidence of severe bd infections via cytology, histopathology, and/or polymerase chain reaction (pcr) at the time of death. ten long-tailed salamanders ( eurycea longicauda) and one two ... | 2018 | 29900788 |
