【Abstract】 Divergent projections of peripheral processes of thoraci-lumbal ganglionic neurons to the renes and somatic have been studied through fluorescein double labelling method. FB and NY were injected into the left rene and the left somatic nerves of the rats respectively. The left T_9-13, L_1-2 DRG are removed and cut into sections by cryostat. The sections are observed under fluorescent microscope and photographed. The results show the three kinds of neurons in the DRG ; （1） single FB labeled neurons ; （2） single NY labeled neurons ; （3） FB and NY double labeled neurons. Double labeled neurons account for 5.8% of total labeled neurons. Present study indicates the divergent projections of the peripheral processes of some spinal ganglion neurons and furthes indicates that these divergences can control both the renes and reletive somatic. This result has provides concrete morpholigical basis for the convergents of somato-visceral sensation in the spinal ganglia level, also for the mechamisms of referred pain.更多还原
