Specific Objectives: Understand the different contributions of the trilaminar embryo to the gastrointestinal tract (GIT) system. Brief understanding of yolk sac, endoderm development and folding. Identify the adult structures developed from the fore-, mid- and hind-gut. Understand the elongation, herniation and rotation of the mid-gut and appreciate the consequences of malrotation. Brief understanding of the development of the liver, pancreas and spleen and identify the functions of these organs in the fetus. Summarise the formation of the adult mesenteries of the gut.

Gastrulation, "to form a gut" is the generation of the trilaminar embryo (ectoderm, mesoderm, endoderm), and is really just the earliest and first stage in GIT development, which is not completed until postnatal function has been established. In this class we will look at some key aspects of GIT development. There will not be time today to cover development of the oral cavity, some of which will be covered in the practical Face and Ear Development.
