1. Subject Description
A study of human embryology with emphasis on the fundamental
developmental processes. Topics include gametogenesis, fertilization,
and development of the embryo from zygote through the differentiation
of the neural tube. Additionally, topics involving development of selected
human organ systems will be covered. Clinical analysis of birth defects
will also be discussed.
2. Require Background or Experience
Cell and Molecular Biology, Histology, Genetics.
3. Subject Objective
A. Throughout this course the students should understand complete
details about the structures, development of human embryo at different
stages including gametogenesis, fertilization, and implantation.
B. By the end of this course the student will demonstrate the ability to
assimilate and integrate information from lectures, practical, tutorial and
independent activities on the gametogenesis, fertilization, implantation,
embryonic period, foetal period and development of the pharyngeal
arches and their derivatives.

Sample of Questions and Answers.
The seven-day blastocyst:
.A) has a single layer of trophoblast at the embryonic pole
.B) has an amniotic cavity
.C) is attached to the endometrial epithelium
D) is called the hypoblast
answer; C
After the morula stage what is the next stage? What is the morphological feature
.that defines this stage??
.
Answer: After passing the morula stage in which the embryo is a compact mass of
cells, the next stage is the blastula stage. In the blastula stage the compactness is
lost and an internal cavity filled with fluid appears inside, the blastocele.
