Neural Pathways of the Sympathetic and Parasympathetic Divisions of the Autonomic

Neural pathways of the sympathetic and parasympathetic divisions of the autonomic nervous system can be distinguished from one another by

A) the number of target organs they have.
B) whether they have an inhibitory or excitatory effect on the target organs.
C) whether preganglionic neurons emerge from the thoracic and lumbar regions of the spinal cord or from the brainstem and sacral region of the spinal cord.
D) whether the cell body of the preganglionic neuron is in the limbic system or spinal cord.
E) the type of preganglionic neurotransmitter they use.
