Localization of motor, sensory and postganglionic sympathtic neurons forming the femoral nerve in Albino rat.
Professional Med J Jan ;3(4):329-9.

The present study yields informations on the location, number and size of motor, sensory and postganglionic sympathetic neurons forming the femoral nerve in albino rats localized by horseradish peroxidase (HRP) method of tracing neuronal connections. It showed that the motor neurons of femoral nerve extended between L1 and L4 segments of the spinal cord. They appeared as groups of neurons occupying anterolateral, posterolateral and central groups. The labeled sensory neurons were located in L1 - L4 dorsal root ganglia (DRG) and were concentrated mostly in L1 DRG with no somatotopic organization of the cells. The postganglionic sympathetic neurons (PSN) were labeled in L1 - L4 sympathetic ganglia with peak frequency in L4 sympathetic ganglion. The somal diameters of motor neurons forming the femoral nerve ranged between 10 and 58 m with majority having somal diameters greater than 25m. The size spectrum of sensory neurons measure between 14 and 60m. The sympathetic neurons measure between 10 and 44m.
