Course Objective

It is aimed to give essential informations about general concepts of embryology, maturation of egg and sperm cells; events associated with fertilization processes; comparative developmental events (cleavage, blatostogenesis, gastrulation, neurulation) from zygote to embryonic period in avenians and mammals; development of the organs and systems in different mammal groups; development of fetal membranes and placenta; congenital malformations occurring in both embryonic and fetal periods.

Learning Outcomes of the Course Unit

1   Explains the basic concepts of embryology.
2   Describes the processes of gametogenesis, fertilization, ovulation, implantation.
3   Explains the processes of zygote cleavage, blastogenesis, gastrulation and neurulation in avenians and mammals.
4   Describes the formation of germ layers in mammals.
5   Counts organs and systems that differ as a result of the advanced development of germ layers and explains their development.
6   Classifies the types of placenta seen in mammals, explains their features.
7   Describes the puberty, estrus cycles, gestation period of mammals, and hormonal control of pregnancy.
8   Counts fetal membranes, explains their developmental and functional properties.
9   Gives examples of in vivo and in vitro reproductive techniques at a level that will provide a basis for clinical training.
