ANA 205
General Embryology
2 Unit(s) (LH 30)
Course Description
At the end of this course, students should be able to:
1. identify gametogenesis and compare the process in male and female;
2. classify the hormonal, ovarian and endometrial cycles, and how they are interconnected;
3. enumerate the preconditions, phases and consequences of fertilization and describe
cleavage and implantation;
4. describe the second week of development as the week of twos, cytotrophoblast and
syncytiotrophoblast, epiblast and hypoblast, somatopleura and splanchnopleure, amniotic
and yolk sac cavities;
5. discuss the establishment of body axes and fate maps during the gastrulation period (third
week) and the role of genes in such process;
6. explain further development of the trophoblast during the third week of development;
7. identify the derivatives of the three germ layers and how they develop during the
embryonic period (third to eighth week); and
8. describe the development of placenta and fetal membranes.
