This chapter reviews the structure of the mammalian egg, and discusses the recent concepts of some of its functions that have come mostly through the application of submicroscopic techniques. The oocytes in most eutherian mammals are in the meiotic prophase at the time of birth, having thus ...

However, these adverse effects occurred in the egg and albumen weight and eggshell breaking strength of the Pantoea-6 (R) and plant extracts groups (P<0.05). Shell weight of the Pantoea-6 (R) group was significantly higher than the other groups (P<0.05). Compared with the control, ...
In recent decades, eggshells of eggs from large-bodied reptiles have been studied by many researchers, to describe the eggshell, to compare them to extinct lineages that once inhabited our planet and also to understand how the egg provides the embryo specific conditions during incubation. In previo...
In the tubes, an egg cell may become fertilized. If it does, it travels through the uterine tube to the body of the uterus. It then incorporates into the uterine wall and starts growing, from embryo to fetus. In case an egg cell is not fertilized, the uterus notices that and starts ...
