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.
