The major pelvic ganglia contain parasympathetic and sympathetic neurons that innervate pelvic organs. Here we describe a dissection method and provide schematics for identification of these ganglia and their associated nerves. These methods can be applied to experimental manipulation of these ganglia in vivo or removal post-mortem for further study.

Source: Svientek, S. R., et al. Fabrication of the Composite Regenerative Peripheral Nerve Interface (C-RPNI) in the Adult Rat. J. Vis. Exp. (2020).This video demonstrates the surgical construction of a composite regenerative peripheral nerve interface (C-RPNI) in a rat model of peripheral nerve injury. The procedure involves attaching a transected peroneal nerve to a muscle graft and overlaying it with a dermal skin graft to promote nerve regeneration. Over time, motor and sensory neurons...
FAQs
Visible anatomical landmarks provide reference points for tracing a nerve and distinguishing its branches from nearby tissues. Magnification allows connective tissue to be removed carefully while the nerve and surrounding structures remain recognizable. This combination helps researchers document the nerve’s pathway and its spatial relationship to a tumor or adjacent organ, supporting more precise anatomical interpretation.
Nerve dissection can clarify whether cancer cells extend along or around a nerve, rather than simply appearing near it. By exposing the nerve pathway and preserving relevant surrounding tissues, researchers can examine the anatomical relationship between tumor and nerve. These observations help characterize perineural invasion and contribute to studies of tumor-associated changes and treatment outcomes.
Preserving the nerve’s structure prevents the anatomical relationship with a tumor from being obscured during examination. Maintaining surrounding tissues also helps researchers assess how the nerve lies relative to adjacent organs and tumor regions. This is important when documenting branches, tracing pathways, or interpreting changes associated with cancer progression and interactions between nerves and cancer.
The technique relies on recognizable anatomical landmarks and controlled removal of connective tissue under magnification. As tissue is cleared, researchers can follow the main nerve, identify branching points, and compare each structure with neighboring tissues. This stepwise exposure supports accurate documentation of nerve anatomy and reduces confusion when tumors or adjacent organs alter the expected anatomical relationships.
A typical examination begins by locating the nerve through visible anatomical landmarks. The researcher then removes connective tissue carefully under magnification, follows the nerve pathway, identifies branches, and records its relationship to the tumor or nearby organs. Preserving the nerve and surrounding tissues throughout these stages supports later anatomical examination and tissue sampling.
Researchers can apply nerve dissection when studying perineural invasion, tumor-associated nerve changes, or interactions between nerves and cancer. The anatomical information can also support surgical planning by showing how nerves relate to tumors and adjacent organs. In addition, the approach contributes to neuropathy studies, tissue sampling, and investigations of treatment outcomes.
By documenting where nerves lie in relation to tumors and identifying changes in nerve anatomy, researchers can examine the interaction between the nervous system and cancer. These observations provide structural context for investigating whether tumor-associated nerve changes relate to progression or treatment outcomes. The method therefore complements broader analyses of tumor biology with detailed anatomical evidence.
