Describe the pathway of the sympathetic nerve impulse as it leaves the spinal cord and travels to the sympathetic chain ganglia. Preganglionic axons from a spinal nerve pass through a white ramus communicans into a sympathetic chain ganglion (aka paravertebral ganglia). Some axons synapse with a postganglionic neuron at the level of entry; others ascend or descend to other levles before synapsing.
