    Abstract

    The segmental distribution of symphathetic preganglionic neurons in the rabbit spinal cord that project to the stellate or the superior cervical ganglion was determined using retrograde tracing with cholera toxin B subunit from the stellate ganglion and wheat germ agglutininapo-horseradish peroxidase-gold from the superior cervical ganglion. Sympathetic preganglionic neurons that projected to the stellate ganglion were located in spinal segments T1 to T10. Sympathetic preganglionic neurons projecting to the superior cervical ganglion were found in segments T1 to T8. Both types of neuron had somata that were elongated in the rostrocaudal direction, and dendrites that were mainly confined to the intermediolateral cell column. Almost 95% of the neurons supplying the superior cervical ganglion had axons that passed through the stellate ganglion.
