The organization of neuronal somata in the first sacral spinal ganglion of the cat (original) (raw)

The organization of neuronal somata in the first sacral spinal ganglion of the cat was investigated through histological techniques. The study found that the largest neuronal cell bodies that likely innervate muscle receptors are distributed throughout the ganglion sectors, reflecting the overall ganglion cell population. After assessing the impact of various nerve lesions, it was noted that affected neurons did not cluster preferentially in any specific ganglion sector, yet they occasionally formed groups across different regions. This distribution suggests a minimal organization based on the type of nerves that innervate peripheral tissues, although some clustering occurs post-nerve lesions.
