C. The consequences of synaptic integration in ganglia 9 and 10 can be studied by selectively stimulating preganglionic inputs to B or C neurons and observing the responses of mucous glands in the skin and of the abdominal aorta. A single preganglionic stimulus applied to the B pathway activates the mucous glands (measured by voltage drop across the skin). Multiple pregang-lionic stimuli applied to the C pathway evoke vasoconstriction (measured here by muscle tension).
