The present set is the unsightful compilation offering a comprehensive account of the Fundamental Principles of Embryology. It not only introduces reproductive physiology, sextual interaction, and environmental responses, but also provides the physiological and endocrinological background. It is a well balanced, completely accessible presentation of principles and application of embryology. In order to create a book which is written within the economy as well s the physical group of the student, only the main essentials of each topic have been presented. This set in fact services a dual function: certain will be of interest of biochemisty, nursing, and paramedical students, it will also be consulted as a references by teachers.

Embryology is a branch of biology which has a most immediate bearing on the problem of life. It has become an immense field whose confines are difficult to delineate. The focus has been and remains on the embryos, on the gradual emergence of form and structure from what appears to be a very modest beginning. The essence of embryonic development is transition from one stage to another. Embryo is a fleeting stage, a continuum along the axis of time.

The present volume Amphibian Embryology deals with the stages of metamorphosis in amphibians. Metamorphosis is a developmental adaptation permitting the change from water to land environment
