In the cat the origin of sympathetic nerve fibers in the medial and posterior articular nerve (MAN and PAN) of the knee joint was studied using retrograde labeling with horseradish peroxidase (HRP). Three to 5 days after uptake of HRP by MAN per cat 404 +/- 136 labeled somata (mean +/- S.D., n = 4 cats) were found mainly in the paravertebral ganglia L4 and L5 of the ipsilateral sympathetic trunk, and uptake of HRP by PAN labeled per animal 532 +/- 155 cell bodies (mean +/- S.D., n = 4 cats) mainly in the paravertebral ganglia L5 and L6. The cross-sectional areas of the labeled somata ranged from 200 to 1300 microns 2 with a mean of about 620 microns 2.

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.

D006735	Horseradish Peroxidase	An enzyme isolated from horseradish which is able to act as an antigen. It is frequently used as a histochemical tracer for light and electron microscopy. Its antigenicity has permitted its use as a combined antigen and marker in experimental immunology.

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.
