Abstract
This study deals with the histomorphology of the mesonephros in male and female Neurergus microspilotus. The slender and narrow kidneys are positioned in the retro peritoneal position up against the ventral aspect of vertebral column and may extend the length from the esophagus-stomach junction to cloaca. The kidney in both sexes is composed of sexual(anterior) and pelvic(posterior) parts. The duct of sexual kidney is a narrow duct which is lying alongside its lateral edge. In the female, it is connected to the ureters and then the duct of defi nitive kidney. Before entering the cloaca, two ureters are joined together and open to the apex of the cloaca. In the male, after entering the sexual kidney, the sperm leave the testis through efferent ducts, then these ducts join together and eventually form Bidder’s duct. The Bidder’s duct joins the Bowman’s capsule of the nephrons in the sexual kidney and the nephrons make collecting ducts which are fi lled with both sperm and urine. After leaving the kidney, all the collecting ducts are connected to the Wolffi an duct. Wolffi an duct joins the ureters(merge from defi nitive kidney) just before entering the cloaca. Based on serial paraffi n sections, nephrons consist of a fi ltration unit, the Malpighian corpuscle, and a renal tubule, which can be divided into 4 morphologically distinct segments: proximal tubule(first and second segment), distal tubule, and collecting tubule. Collecting tubules merge and form a branch system that opens into collecting ducts.
期刊介绍:
AHR aims to provide a forum for herpetologists and related scientists interested in conducting international academic exchanges and joint studies, and a platform for introducing their newly made scientific and technological data, and publishing their research results and achievements in the world, but focusing on the Asian-Pacific Region.
The principal criteria of AHR for acceptance of articles for publication are the quality and significance of the research, breadth of interest of the work to the readership, and the clarity and effectiveness of communication. AHR welcomes submission of manuscripts from authors in all countries of the world, though with a focus on the herpetological studies in the Asian and Pacific Region, including major articles, shorter communications and review articles.
