✦ Synopsis
The immunochemical distribution of peptidergic and aminergic neurotransmitters in the exocrine pancreas of the Houbara bustard, Chlamydotis undulata, was determined. Immunoreactivity to choline acetyltransferase (ChAT), vasoactive intestinal polypeptide (VIP), and galanin (Gal) occurred mainly as varicose terminals in the walls of capillaries around the acini and arterioles within the connective tissue. Neuronal cell bodies immunoreactive to ChAT were infrequently observed. Neuropeptide Y (NPY), pancreatic polypeptide (PP), and somatostatin (Som) were observed mainly in intra-acinar cell bodies but nerve fibers immunoreactive to these neuropeptides were also seen along the basal surfaces of the acini. Immunoreactivity to NPY and PP was also discern-
