Abstract: | During oogenesis lipids continue to increase in Ascaridia galli leading to the formation of massive accumulations in larger oocytes. In addition to neutral lipids (triacylglycerols), small amounts of cholesterol and granules containing phospholipids and lipoproteins are seen in the ooplasm of growing and mature oocytes. Lipid inclusions of oogonia which are in the form of coarse granules show a complex structure in young oocytes and form droplets and globules in growing and mature oocytes. Changes in the morphology of the oocytes are accompanied by changes in the distribution of lipids within the oocytes. Localization of lipids in rachis and ovarian epithelium along the length of the ovary is also described. |
