Adrenergic and cholinergic innervation of the chicken pancreas

Abstract

The distribution, as well as the morphological characteristics of adrenergic and cholinergic nerve fibres was studied in the pancreas of the hen and the cock. The presence of numerous adrenergic and moderately numerous cholinergic structures was revealed in the organ. They were seen as nerve fibre bundles or single nerve fibres located in the vicinity of blood vessels and exocrine ducts, as well as the cells of the exocrine and endocrine pancreas. Single TH- and ChAT-positive nerve cell bodies were also found in the organ under study.
