Using a fluorescent compound as a retrograde neuronal tracer for the identification of a specific motoneuron pool, we examined the soma diameter and oxidative enzyme activity of alpha-motoneurons innervating the extensor digitorum longus (EDL) and the soleus (Sol) muscles in the rat. An inverse relationship between soma diameter and oxidative enzyme activity was demonstrated in the EDL, while there was no significant relationship between these variables in the Sol. These results suggest that an inverse relationship between soma diameter and oxidative enzyme activity cannot always be demonstrated in all of the motoneuron pools.

D008856	Microscopy, Fluorescence	Microscopy of specimens stained with fluorescent dye (usually fluorescein isothiocyanate) or of naturally fluorescent materials, which emit light when exposed to ultraviolet or blue light. Immunofluorescence microscopy utilizes antibodies that are labeled with fluorescent dye.

D010084	Oxidation-Reduction	A chemical reaction in which an electron is transferred from one molecule to another. The electron-donating molecule is the reducing agent or reductant; the electron-accepting molecule is the oxidizing agent or oxidant. Reducing and oxidizing agents function as conjugate reductant-oxidant pairs or redox pairs (Lehninger, Principles of Biochemistry, 1982, p471).	Redox,Oxidation Reduction
D011919	Rats, Inbred Strains	Genetically identical individuals developed from brother and sister matings which have been carried out for twenty or more generations or by parent x offspring matings carried out with certain restrictions. This also includes animals with a long history of closed colony breeding.

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.
