(3) To allow this rotation to take place and probably for some other unknown reason, part of the dorsal mesogastrium, which is attached to the great curvature or dorsal border of the stomach, undergoes a rapid growth and forms the great omentum (Fig. 214). The stomach loses its original vertical position only to a slight degree; even in the adult the pyloric orifice lies not far from the middle line; the oesophageal slightly to the left of it. The glands of the stomach begin to form during the third month. They appear as tubular invagination of the gastric hypoblast. The peptic cells are formed by the 7 th month.
