In the dorsal horn the most intense fluorescence was seen in the superficial layers. The motoneuron neuropil exhibited the most prominent catecholamine\u2010fluorescence of the ventral horn layers. In the sixth lumbar segment, which contains the motor nuclei that innervate the pelvic striated muscles as well as one innervating muscles in the lower limb, a differential distribution of the density of catecholamine fluorescence was presented by the individual nuclei.<\/jats:p><jats:p>The catecholamine fibers in the motoneuron neuropil were seen closely surrounding the motoneuron somata, suggesting the existence of axosomatic contacts, and by utilizing the fluorescent retrograde tracer True Blue in combination with the ALFA method tentative axosomatic noradrenergic synapses on identified neurons innervating small striated pelvic muscles could be visualized in the light microscope.<\/jats:p><jats:p>In the intermediate gray the intermediolateral nucleus in thoracic and upper lumbar segments was the most heavily innervated area, followed by the medial lumbar sympathetic group, which contains the majority of the sympathetic preganglionic neurons innervating the pelvic organs. The parasympathetic intermediolateral nucleus in the upper sacral segments received a catecholamine innvervation of moderate density.<\/jats:p><jats:p>The catecholamine innervation pattern is discussed in relation to the patterns of other putative transmitters. The distribution of catecholamine fluorescence in relation to nuclei that control the pelvic organs differs from the arrangement of other transmitters in this region. The complexity of the innervation of the pelvic organs and their related striated muscles is thus further stressed.<\/jats:p>","DOI":"10.1002\/cne.902420305","type":"journal-article","created":{"date-parts":[[2005,5,27]],"date-time":"2005-05-27T20:54:44Z","timestamp":1117227284000},"page":"358-368","source":"Crossref","is-referenced-by-count":44,"title":["Catecholamine innervation of the caudal spinal cord in the rat"],"prefix":"10.1002","volume":"242","author":[{"given":"Henrik Daa","family":"Schr\u00f8der","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gunnar","family":"Skagerberg","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2004,10,9]]},"reference":[{"key":"e_1_2_1_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/0304-3940(79)96068-3"},{"key":"e_1_2_1_3_1","doi-asserted-by":"crossref","first-page":"301","DOI":"10.1016\/0165-0270(80)90018-7","article-title":"The aluminum\u2010formaldehyde (alfa) histofluorescence method for improved visualization of catecholamines and indoleamines. 2.
