Learning outcomes
Describe the structures and the development of the human embryo at different stages, including gametogenesis, fertilization, and implantation.
Course contents
Learning outcomes: At the end of the course the students will know the mechanisms that control human embryogenesis and morphogenesis. They are familiar with tissue origin from germ layers, organogenetic mechanisms of the embryo and embryonic stem cells.
Objectives: Knowledge of the basic aspects of human embryogenesis and morphogenesis.
Program: Embryology- Characteristics of the mechanisms that control human embryogenesis and morphogenesis.

Articles provided during the frontal lessons
Teaching methods
A combination of frontal lessons and lessons inter-pares on specific topics. The acquisition of the knowledge will be frequently monitored with online tests
Assessment methods
The students will be evaluated by written exam, with multiple choice tests and open questions on the EOL - Exam OnLine Platftorm. During the written test, a mark scoring from 0 to 6 will be displayed next to the relevant question.The final mark is given by the arithmetic sum of the scores from each answered question. Wrong answers or missing answers will score as 0.
Interpretation of the score:
- <18 – failure, not scored. The student fails to satisfactorily address all of the questions.
- 18 Poor. The student inadequately addresses most of the questions with serious inherent weaknesses.
- 21– Fair. The student broadly addresses most of the questions, but there are significant weaknesses.
- 24– Good. The student addresses the questions well, but a number of shortcomings are present.
- 27– Very good. The student addresses the criterion very well, but a small number of shortcomings are present.
- 30– Excellent. The student successfully addresses all relevant aspects of the questions. Any shortcomings are minor.
- 30 cum laude. The student successfully addresses all relevant aspects of the questions with no shortcomings.
The final score will be a "weighted average mark":
- Alert- Attendance Requirements - Alert-
Attendance to this learning activity is mandatory; the minimum attendance requirement to be admitted to the final exam is 66% of lessons. For Integrated Courses (IC), the 60% attendance requirement refers to the total amount of I.C. lessons. Students who fail to meet the minimum attendance requirement will not be admitted to the final exam of the course and will have to attend relevant classes again during the next academic year. Professors may authorize excused absences upon receipt of proper justifying documentation, in case of illness or serious reasons. Excused absences do not count against a student’s attendance record to determine their minimum attendance requirement.
