Abstract

The sympathetic preganglionic neurons located in the intermediolateral nucleus (IML) that project to the superior cervical ganglion of the rabbit were observed to have two major dendritic orientations after retrograde labeling with horseradish peroxidase. One projection extends longitudinally within IML. The second projection courses medially and presents a triangular shape in horizontal sections. The labeled processes that project medially arise from cells in IML and project through the intercalated nucleus towards the central autonomic area and follow the contour of the central canal. Medially oriented dendrites intruding into other areas of the intermediate grey matter show that IML is an 'open' rather than a 'closed' nucleus as has been recently suggested. The location and distribution of the sympathetic preganglionic neurons projecting to the superior cervical ganglion in the rabbit are compared with those reported for other species.
