Embryology of Domestic Animals

Teacher(s)

Rivas Leonel Ellen;

Language

French

Prerequisites

A good knowledge of the elementary zoology and the cellular and molecular biology is absolutely necessary

Main themes

The course is divided into two parts:
- The embryonic period consists of gametes production, fertilization and the embryo development until its implantation in the domestic mammal species as well as the different types of placentation. The embryonic development of the bird embryo is also envisaged. An important chapter on the biotechnologies of the mammalian embryo ends this first part.
- The fetal period consists of the development of the various organs and systems as well as their abnormalities of development observed in our domestic species (horse, bovine, carnivores, pig and hen).

Learning outcomes

At the end of this learning unit, the student is able to :
1	Specific learning outcomes of the course Understand the basic processes involved in the embryonic development and the differentiation of tissues, organs and systems of organs of our domestic mammals and the bird. That knowledge will help the student to understand more efficiently the anatomical and physiological aspects of the adult animal and the origin of the congenital abnormalities. The accent is put on the aspects more particularly important for the veterinary practice.
Contribution of the course to the learning outcomes of the Bachelor of Veterinary Medicine programme. This course contributes to points 1.2.2; 2.7 of the learning outcomes.

Content

Copilot said: 

The course is divided into two parts: embryogenesis and organogenesis.
Embryogenesis comprises four chapters:

1. Fertilization
2. The study of the early stages of development: cleavage, blastulation, elongation, gastrulation, and body folding
3. The study of fetal membranes, implantation, and placentation patterns
4. Assisted reproductive technologies

Organogenesis covers the development and developmental abnormalities of each organ system. The following organ systems will be addressed in sequence:

1. The circulatory system
2. The nervous system
3. The sensory organs
4. The respiratory and digestive systems
5. The urogenital system

Teaching methods

Lectures are delivered by the course instructor and present key concepts through conceptual and dynamic diagrams.

Practical sessions are conducted by teaching assistants in the laboratory.

Evaluation methods

Written examination. Questions (multiple-choice and open-ended) will cover all the material presented during the ex cathedra lectures.

Online resources

Course materials are provided in the form of illustrated and referenced syllabi available on the Moodle platform. Lecture slides will also be made available prior to each lecture.
Some videos are made available to students. These videos provide a dynamic illustration of the construction of more complex diagrams.
