A 29-year-old man comes to a local hospital with duodenal peptic ulcer and complains of cramping epigastric pain. Which of the following structures harbors the cell bodies of abdominal pain fibers?
1.Lateral horn of the spinal cord
2.Anterior horn of the spinal cord
3.Dorsal root ganglion
4.Sympathetic chain ganglion
5.Celiac ganglion
Cell bodies of the abdominal pain fi bers are located in the dorsal root ganglion. The lateral horn of the spinal cord contains cell bodies of sympathetic preganglionic nerve fi bers; the anterior horn contains cell bodies of general somatic efferent (GSE) fi bers. The sympathetic chain ganglion contains cell bodies of sympathetic postganglionic fi bers, which supply blood vessels, sweat glands, and hair follicles. The celiac ganglion contains cell bodies of sympathetic postganglionic fi bers, which supply the visceral organs such as stomach and intestine.
