37193 - Histology and Embryology 2 (A-K)

Learning outcomes

Describe the structures and the development of the human embryo at different stages, including gametogenesis, fertilization, and implantation.

Course contents

PROGRAM of the course of Histology and Embryology 2

Hints of gametogenesis. Fertilization and zygote formation. Concept of totipotency.

First week of development

Fertilization – Cleavage - Formation of blastocyst

Second week of development

Implantation: adhesion, invasion, decidual reaction - Syncytiotrophoblast and cytotrophoblast - Epiblast and hypoblast - Formation of the amniotic cavity and the yolk sac - Formation of the chorionic cavity

Third week of development

Gastrulation and formation of the three germ layers and their derivatives – Neurulation - Histogenesis - Stem cells and differentiation

Fourth week of development

Folding of embryo - Head and tail folds - Lateral folds - Beginning of organogenesis - Derivatives of the three embryonic layers

Embryo-fetal annexes

Yolk sac – allantoid – amnion – placenta - umbilical cord

Teratogenesis

Teaching methods

The course will take place in 16 hours of frontal lecture. Specific iconography will be showed to support the theoretical bases. The acquisition of the knowledge will be frequently monitored through interaction with students.

Assessment methods

The end-of-course exam consists of an interview aimed at evaluating the achievement of the following educational objectives:

§ know the different stages of the human embryo development

§ understand how alterations at different stages of physiological developmental processes lead to the manifestation of birth defects

The vote attributed to the Histology and Embryology 2 test will do average with the votes achieved in the contextual test of Histology and Embryology 1, accessed after passing the practical test for recognition of histological slides. The final vote of the integrated course that will be expressed in thirtieths. The online registration to the examination is mandatory.

Teaching tools

PowerPoint presentations and interactive lessons. The material used during the lessons is available since the first lesson by login at the Platform for teaching support service - VIRTUALE. Auto evaluation tests online.
