CONCLUSION: The dorsal portion of the L5-L6 disc of rats was shown to be multisegmentally innervated by the T13 to L6 dorsalrootganglia.
Afferent perikarya in dorsalrootganglia (DRG) at the T13 and L1 segmental levels projecting to the rat ovary were identified by utilizing the fluorescent retrograde tracer true blue (TB).
The neuroanatomical results show that the T13 and L1 dorsalrootganglia provide major afferent innervation to the cranial portion of the reproductive tract and the L6 and S1 dorsalrootganglia provide primary afferent fibers to the caudal portion of the reproductive tract as well as the bladder, rectum and perineum.
