Anatomical analysis of sensory ganglia in mice

Ganglia are nodular structures in the peripheral nervous system (PNS) that formed by a cluster of neuron somas. They have important roles communicating signals from organs to and work as unique structure PNS. As great advances neuronal manipulation recording techniques been made, an increasing amount research is focused on function ganglia. However, ganglion surgery still very challenging, particularly small animals such mice. In present study, we performed anatomical analyses two types sensory ganglia, dorsal root ganglia trigeminal Hematoxylin eosin (H&E) staining revealed structural differences between nerve fibers. Immunofluorescence with antibodies nuclear antigen (NeuN), neuron-specific marker, labels neurons distinguishes other tissues, lymph nodes. This study describes analysis which provides basis for functional studies.
