| comparative anatomy and phylogeny of the cloacae of salamanders (amphibia: caudata). vi. ambystomatidae and dicamptodontidae. | histology of the cloacae of rhyacotriton olympicus and representative species from the genera ambystoma and dicamptodon was examined by light microscopy. females of ambystoma possess sperm storage glands, the spermathecae, as well as ventral glands and dorsal glands, both of uncertain function. females of ambystoma examined from the subgenus linguaelapsus differ from those in the subgenus ambystoma by possessing more extensive ventral gland clusters and a shorter cloacal tube. females of dicampt ... | 1992 | 1507243 |
| ultrastructure and histochemistry of the vas deferens of the salamander rhyacotriton olympicus: adaptations for sperm storage. | the vas deferens of the salamander rhyacotriton olympicus is composed of (1) a peritoneal epithelium, (2) connective tissue with fibroblasts, melanophores, circular smooth muscle, capillaries, and unmyelinated nerves within a collagenous matrix, and (3) an inner layer of cuboidal epithelium partially covered by ciliated squamous cells at the lumen. the lumen and apical cytoplasm of both epithelial cell types contain strongly pas-positive granules. the cuboidal cells contained numerous swollen ro ... | 1988 | 3399848 |
