The infundibulum of five iguanas was remarkably distinct from the uterus, and was also clearly demarcated into cranial (expanded v\u2010shaped) and caudal (tubular) divisions. Tissue samples obtained from five portions (three from the cranial division and two from the caudal division) of the infundibulum were processed conventionally for light and electron microscopy. The epithelial lining of the most anterior, middle, and posterior, parts of the cranial division displayed nonciliated cells predominantly, and occasionally ciliated cells. The numerous secretory granules in nonciliated type 1 cell found in the fimbrial aspect of the infundibulum were homogenous and deeply electron\u2010dense, but those in the other two regions were variants of this cell type because they contained variably electron\u2010dense secretory granules. Two main types of nonciliated cells (type 2 and its variant, type 3, as well as type 4) occurred in the epithelial lining of the caudal division of the infundibulum, but they, clearly, showed no dense secretory granules. Whereas the nonciliated type 2 cell and its variant (type 3 cell) contained large glycogen deposits, the type 4 cell lacked these deposits but its apical part contained large lipid\u2010like droplets and, remarkably, blebbed into the duct lumen. The nonciliated cells lining the mucosal tubular glands contained highly electron\u2010dense secretory granules, which were similar to those found in the nonciliated type 1 cell in the epithelial lining of the fimbrial part of the cranial division of the infundibulum.<\/jats:p>","DOI":"10.1002\/jmor.21644","type":"journal-article","created":{"date-parts":[[2023,10,10]],"date-time":"2023-10-10T12:46:42Z","timestamp":1696942002000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["The ultrastructural features of the infundibulum of the green iguana, <i>Iguana iguana<\/i>"],"prefix":"10.1002","volume":"284","author":[{"ORCID":"https:\/\/orcid.org\/0009-0008-5852-8832","authenticated-orcid":false,"given":"Crissy\u2010Ann","family":"Harrylal","sequence":"first","affiliation":[{"name":"Department of Anatomy, Physiology, and Pharmacology School of Veterinary Medicine St. George's University True Blue Grenada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Antoinette V.","family":"Lensink","sequence":"additional","affiliation":[{"name":"Electron Microscope Unit, Department of Anatomy and Physiology, Faculty of Veterinary Science University of Pretoria Pretoria South Africa"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sunil K.","family":"Gupta","sequence":"additional","affiliation":[{"name":"Department of Anatomy, Physiology, and Pharmacology School of Veterinary Medicine St. George's University True Blue Grenada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tom A.","family":"Aire","sequence":"additional","affiliation":[{"name":"Department of Anatomy, Physiology, and Pharmacology School of Veterinary Medicine St. George's University True Blue Grenada"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2023,10,8]]},"reference":[{"issue":"2","key":"e_1_2_11_2_1","first-page":"190","article-title":"Oviductal morphology and sperm storage in the keeled earless lizard, Holbrookia propinqua","volume":"44","author":"Adams C.
