Abstract

Introduction: Dorsal root ganglia of spinal nerves are developed from neural crest cells (NCCs). NCCs are originated from neuroectoderm at the neurosomatic junction. Separation of NCC from the edges of neural folds involves local disruptions of basal lamina and disappearance of intercellular junctions.
Aim: To determine the existence of ganglia over the dorsal rootlets of all the spinal nerves.
Materials and Methods: A number of 25 formalin-fixed adult human cadavers were utilized for the study. Of 25 cadavers, 18 were male and 7 were female. Removal of spinal cord was done by conventional spinal cord dissection method (posterior approach) as per Cunningham’s manual.
Results: This study shows that ganglia are present in the dorsal rootlets of spinal nerves. The dorsal rootlet ganglia are identified in the dorsal rootlets of cervical region and also in the cauda equina region.
Conclusion: This study will be a stimulant in the field of clinical embryology, neuroanatomy, anesthesia, etc., to find the reason and importance of their existence. This may be considered as a special adaptation for a specific sensation.
