- Abstract
A tyrosine hydroxylase-immunoreactive cell mass is found in the caudal portion of the dorsal nerve ganglion of the red-eared slider, Trachemys scripta elegans. The ganglion appears as a flat oval structure in the horizontal plane, where the major axis runs latero-medially, and the minor axis rostro-caudally in the ventral view. A communicating branch to the sympathetic chain diverges from the top of each tubercle which lies on the caudo-lateral side of the ganglion. A tyrosine hydroxylase- immunoreactive cell mass is located in this tubercle. This cell mass exists in both sexes. Tyrosine hydroxylase-immunoreactive cells, that contain Nissl bodies in cytoplasm and are enveloped by the satellite cells, are multipolar and their neural processes are distributed in a distal direction into the spinal nerve. The range of distribution of the synapsin I-immunoreactive structures is limited to the tyrosine hydroxylase-immunoreactive cell mass. The chelonian dorsal spinal nerve ganglia are a conglomerate of the spinal nerve ganglion proper and the sympathetic ganglion. Copyright © 2009 S. Karger AG, Basel
