vasoconstrictor fibers ofthe pulmonary vessels. The largest ganglion of the abdomen, the celiac, has its chief root inthe celiac plexus in the major and minor splanchnic nerves, the formerof which comes from D 4-9, the latter from D 10-12. As the mesentericnerves they innervate the stomach glands, liver, pancreas, spleen,kidneys, adrenals, and intestine as far as the ascending colon. Theinferior mesenteric ganglion receives its precellular fibers from L 1-3and sends its postganglionic fibers to the colon and as the hypogastric,in part, to the anus, bladder, sphincter of bladder and genitals. Higier, loc. cit. 82 VEGETATIVE OR VISCERAL NEUROLOGY A series of blood glands, chromaffine cell containing structures(paraganglia) have of late been regarded as closely related to theseclearly recognized ganglia of the vegetative system. The mostimportant of these are: (a) Paraganglion caroticum, (6) paraganglioncoccygeus, (c) paraganglion aorticum, and (d) paraganglion supra-renalis or adrenals.

Sympatheticfibers are indicated by unbroken lines; parasympathetic (autonomic) by dotted lines.(Timme, loc. cit.) Sympathetic and Autonomic Division.—Anatomically as well aspharmacologically it appears that two types of physiological activityare present in the vegetative nervous system. These are the sympa-thetic and the autonomic. All those non-voluntarily influencedorgans, smooth muscle structures, heart muscle, glands, whose nervefibers are derived from the spinal cord from the first dorsal above to AUTONOMIC AND SYMPATHETIC NERVOUS SYSTEMS 83 the fourth lumbar segment below, belong in the sympathetic systemin the narrower sense. All others are controlled through the para-sympathetic or autonomic. The uppermost come from the midbrain,enter the ciliary ganglion, and are distributed to the smooth internalmuscle of the eye. A second or bulbar autonomic system comes throughthe facial a
