Summary

The authors studying adrenergic innervation of the spleen in chickens by means of the glyoxylic acid histofluorescence method have made the folloving conclusions: Adrenergic nerve fibres enter the organ in a common bundle with a. lienalis and continue in the forms of thicker fibres carrying periarterial nerves and thinner adventitial nerves. The density of these nerve plexuses is especially apparent around larger arteries and aa. centrales, where varicosed nerve profiles, lying on the borderline between their media and adventitia, are represented abundantly.
Reaching out, thinner nerve twigs run to the adjacent layers of connective tissue as well as to the red and white pulp. There is a very obvious occurrence of individual nerve profiles, lining lymph follicles and periarteriolar lymphatic sheat (PALS). The innervation of the walls of large veins is unusually rich. Intense fluorescent nerve profiles can also be seen in the fibrous capsula of the organ.
Microscopic findings are consistent with the view that adrenergic nerve components in the spleen participate both in the regulation of vascular motility and in the regulation of the microenvironment of the red and white pulps of the organ.
