Describe the possible ways in which the axon of a sympathetic preganglionic neuron connects with postganglionic neurons after it reaches the sympathetic trunk ganglia
What will be an ideal response
The axon may 1 ) synapse with postganglionic neurons in the first ganglion it reaches, 2 ) ascend or descend to higher or lower ganglia via sympathetic chains, or 3 ) continue without synapsing through sympathetic trunk ganglia to end at a prevertebral ganglion and synapse with postganglionic neurons there. 4 ) also pass, without synapsing, through the sympathetic trunk ganglion and a prevertebral ganglion and then extend to chromaffin cells of the adrenal medullae that are functionally similar to sympathetic postganglionic neurons.
