Clinical Embryology
Exam Answer Key
Course Introduction
Clinical Embryology explores the scientific principles and clinical applications of human embryonic development, with a focus on the processes from gametogenesis, fertilization, and preimplantation development through organogenesis and fetal growth. The course examines normal and abnormal development, genetic and environmental factors influencing embryogenesis, and the pathogenesis of congenital anomalies. Students gain insight into assisted reproductive technologies (ART), prenatal screening and diagnosis, and embryological foundations relevant to clinical practice, equipping them with the knowledge necessary to integrate embryological concepts into medical and healthcare settings.
