Introduction
This chapter provides an introduction to the embryology
of the canine abdomen.
The primitive gut tube, consisting of foregut, midgut
and hindgut, is suspended from the dorsal body wall by a dorsal
mesentery. Part of the primitive gut tube also has a ventral mesentery
attaching it to the ventral body wall.
Mesenteries allow blood vessels and nerves to reach
the organs they suspend.
Mesothelium, a mesodermally-derived simple squamous
epithelium, covers the mesenteries and the linings of the closed
body cavities as serous membranes.
