one source date February 2012 no footnotes date February 2012 An ovariole is one of the tubes of which the ovary ovaries of most insect s are composed. Typically an insect will have two ovaries. The constituent ovarioles lead to two oviducts, which converge into a single oviduct. The ovarioles are composed of a germarium and a set of ovarial follicles. In D. melanogaster File DrosophilaOvary.png 200px thumb right In Drosophila melanogaster , there are 16 ovarioles per ovar and, there are 2 ovaries. The most anterior portion of the ovariole consist of the germarium, the location of germ line stem cells GSC s , terminal filaments, cap cells and intergermarial sheath cells. The GSC s are what later on give rise to egg s. There are 14 distinct stages in the development of oocyte, and the progression in development occurs anterior to posterior along the ovariole. At the end of stage 14, the egg passes through the lateral oviduct before entering the common oviduct and then exiting via the uterus. 1913 Category Insect anatomy insect anatomy stub fr Ovariole ... more details
