Developmental biology is the forefront of research in the life sciences today and is engaged in deciphering the processes occurring during the transformation of a single cell , the fertilized egg, into an embryo and a mature organism . The course will follow the steps that describe the processes of early development and later discussed the development of various body systems, the central and peripheral nervous systems , the eye and skeleton. The course will describe the development of genetic and molecular level through cellular aspects to the whole animal. We will explore both normal development and diseases resulting from abnormal development. Students will become familiar with various animal models, as well as the tools and techniques through which one can explore stages and mechanisms acting during development.
The course is designed to expose students to various mechanisms involved in the creation of an organism. This course is unique as it examines development at a variety of levels form a whole organism, through tissue and cell, to molecules and genes.
Learning outcomes - On successful completion of this module, students should be able to:
1. Identify structures and stages of development in different organisms. 2. Describe the signal transduction pathways operating in the development and analyze situations in which they are not working properly. 3. Correlate diseases with genetic or developmental abnormalities.
Teaching arrangement and method of instruction:
Lecture, exercise, computer exercises,computerized exams.
