Sympatho--adrenergic neural control of the sphincter of Oddi of the cat and the dog. 1979

K Kyösola

The presence of adrenergic axons within the sphincter of Oddi of the cat and dog was demonstrated using the glyoxylic acid-induced fluorescence histochemical method. After vagotomy (in cats), no reduction was observed in the number of the adrenergic axons or in the fluorescence intensity. It is concluded that the sphincter of Oddi receives direct adrenergic neural control derived from the sympathetic plexuses and ganglia, whereas the vagal contribution of adrenergic axons is negligible, if it exists at all.

UI	MeSH Term	Description	Entries
D009803	Sphincter of Oddi	The sphincter of the hepatopancreatic ampulla within the duodenal papilla. The COMMON BILE DUCT and main pancreatic duct pass through this sphincter.	Oddi's Sphincter,Oddi Sphincter,Oddis Sphincter,Sphincter, Oddi's
D002415	Cats	The domestic cat, Felis catus, of the carnivore family FELIDAE, comprising over 30 different breeds. The domestic cat is descended primarily from the wild cat of Africa and extreme southwestern Asia. Though probably present in towns in Palestine as long ago as 7000 years, actual domestication occurred in Egypt about 4000 years ago.

D004285	Dogs	The domestic dog, Canis familiaris, comprising about 400 breeds, of the carnivore family CANIDAE. They are worldwide in distribution and live in association with people. (Walker's Mammals of the World, 5th ed, p1065)	Canis familiaris,Dog

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.

D001369	Axons	Nerve fibers that are capable of rapidly conducting impulses away from the neuron cell body.	Axon
D013564	Sympathetic Nervous System	The thoracolumbar division of the autonomic nervous system. Sympathetic preganglionic fibers originate in neurons of the intermediolateral column of the spinal cord and project to the paravertebral and prevertebral ganglia, which in turn project to target organs. The sympathetic nervous system mediates the body's response to stressful situations, i.e., the fight or flight reactions. It often acts reciprocally to the parasympathetic system.

D014670	Ampulla of Vater	A dilation of the duodenal papilla that is the opening of the juncture of the COMMON BILE DUCT and the MAIN PANCREATIC DUCT, also known as the hepatopancreatic ampulla.
