Ultrastructural localization of vasoactive intestinal polypeptide (VIP) was studied in the chicken pancreas by the immunocytochemical method. VIP-immunoreactive nerve endings were found in contact with acinar cells in the pericapillary space or between acinar cells. They also terminated on epithelial cells of arteriolae. In pancreatic islets, VIP-immunoreactive nerve endings were in contact with B-cells, but not with A- or D-cells. VIP-immunoreactive terminals contained many small clear vesicles which indicate the cholinergic feature. Nerve endings containing many small clear vesicles but not showing VIP-immunoreactivity were also detected in both the exocrine and endocrine pancreas. According to these data and the previous studies concerning the cholinergic and VIPergic innervation of the chicken pancreas, it is suggested that VIP-containing cholinergic nerves innervate B-cells and cholinergic nerves not containing VIP innervate D-cell.

D009412	Nerve Fibers	Slender processes of NEURONS, including the AXONS and their glial envelopes (MYELIN SHEATH). Nerve fibers conduct nerve impulses to and from the CENTRAL NERVOUS SYSTEM.	Cerebellar Mossy Fibers,Mossy Fibers, Cerebellar,Cerebellar Mossy Fiber,Mossy Fiber, Cerebellar,Nerve Fiber
D010179	Pancreas	A nodular organ in the ABDOMEN that contains a mixture of ENDOCRINE GLANDS and EXOCRINE GLANDS. The small endocrine portion consists of the ISLETS OF LANGERHANS secreting a number of hormones into the blood stream. The large exocrine portion (EXOCRINE PANCREAS) is a compound acinar gland that secretes several digestive enzymes into the pancreatic ductal system that empties into the DUODENUM.
D002645	Chickens	Common name for the species Gallus gallus, the domestic fowl, in the family Phasianidae, order GALLIFORMES. It is descended from the red jungle fowl of SOUTHEAST ASIA.	Gallus gallus,Gallus domesticus,Gallus gallus domesticus,Chicken

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D014660	Vasoactive Intestinal Peptide	A highly basic, 28 amino acid neuropeptide released from intestinal mucosa. It has a wide range of biological actions affecting the cardiovascular, gastrointestinal, and respiratory systems and is neuroprotective. It binds special receptors (RECEPTORS, VASOACTIVE INTESTINAL PEPTIDE).
