An ultrastructural study of sympathetic ganglion satellite cells in the rat. 2. Effect of preganglionic sympathectomy. 1976

P L Chang, and J J Taylor, and W Wozniak, and P A Young

The ultrastructure of satellite cells of the rat superior cervical ganglion was studied following preganglionic sympathectomy.Several distinct morphological alterations were observed: (a) enlargement of the intercellular space between the ganglion cells and the satellite cells, (b) dilation of the granular endoplasmic reticulum and loss of attached ribosomes, and (c) swelling of the mitochondria with disorganization of the cristae mitochondriales. The presence of degenerating nerve fibers and synaptic boutons was also noted.

D008297 Male Males
D009410 Nerve Degeneration Loss of functional activity and trophic degeneration of nerve axons and their terminal arborizations following the destruction of their cells of origin or interruption of their continuity with these cells. The pathology is characteristic of neurodegenerative diseases. Often the process of nerve degeneration is studied in research on neuroanatomical localization and correlation of the neurophysiology of neural pathways.

D005725 Ganglia, Autonomic Clusters of neurons and their processes in the autonomic nervous system. In the autonomic ganglia, the preganglionic fibers from the central nervous system synapse onto the neurons whose axons are the postganglionic fibers innervating target organs. The ganglia also contain intrinsic neurons and supporting cells and preganglionic fibers passing through to other ganglia. Autonomic Ganglia,Ganglion, Autonomic,Autonomic Ganglion
