Embryology

by John McLachlan, PhD, Peter Ward, PhD

Embryology is the branch of biology that focuses on the study of embryos and their development. In the medical field, this branch narrows to the study of the development of human embryos, with the objective of finding the root causes of congenital abnormalities.

For optimal understanding, the student needs to be familiar with the components of the cell, the cell cycle, cell division, gene expression, genome replication, the differences between diploid and haploid cells, and the process of fertilization. Basic knowledge of human anatomy is also required.

Throughout the development process, a multiplicity of genes and structures interact in a harmonious manner in order to develop a human fetus. This process progresses by stages and requires the expression of the right genes at the right place and the right time.

During development, these processes may be hindered, resulting in structural or functional abnormalities in the fully developed child. There are many examples of abnormalities, such as atrial septal defects (ASD), a communication between the atria caused by nonclosure of the foramen ovale, and syndactyly, the joining of two fingers due to inadequate apoptosis of cells in between the digits when these were differentiating.

In order to make an adequate diagnosis, the competent physician must be aware of the most prevalent genetic abnormalities in his or her area of work, and be familiar with the typical clinical presentation of the most common genetic syndromes.

Very well explained
By NAME L. on 14. July 2021 for System-Specific Embryology with John McLachlan

General and systemic embryology very well explained. Chambers of the heart, formation of septums very well explained.
