This study demonstrates the presence of adrenergic nerve fibres in the spleen of the pheasant after hatching. A fluorescent histochemical method using glyoxylic acid was used to visualize the adrenergic nerve fibres. Intensively fluorescent nerve fibres were found in several parts of the spleen. An abundant occurence of these fibres was seen in the periarterial course. The visible nerve fibres ran along the splenic artery branches as longitudinal nerves or they formed fine plexuses in the wall of vessels. In such a way the nerve fibres reached the central artery. Some of these nerve fibres, detaching from the periarterial course, entered the red pulp and they were observed also in the splenic capsule while adrenergic nerve fibres were found in the wall of the small and larger splenic veins. These findings suggest that the spleen of the pheasant is under the influence of adrenergic innervation.


Key words: adrenergic, nerve fibres, spleen, pheasant.
