The superior mesenteric glands may be divided into three principal groups: mesenteric, ileocolic, and mesocolic.
The Mesenteric Glands (lymphoglandulæ mesentericæ) lie between the layers of the mesentery. They vary from one hundred to one hundred and fifty in number, and may be grouped into three sets, viz.: one lying close to the wall of the small intestine, among the terminal twigs of the superior mesenteric artery; a second, in relation to the loops and primary branches of the vessels; and a third along the trunk of the artery.
The Ileocolic glands (Figs. 615,616), from ten to twenty in number, form a chain around the ileocolic artery, but show a tendency to subdivision into two groups, one near the duodenum and another on the lower part of the trunk of the artery. Where the vessel divides into its terminal branches the chain is broken up into several groups, viz.: (a) ileal, in relation to the ileal branch of the artery; (b) anterior ileocolic, usually of three glands, in the ileocolic fold, near the wall of the cecum; (c) posterior ileocolic, mostly placed in the angle between the ileum and the colon, but partly lying behind the cecum at its junction with the ascending colon; (d) a single gland, between the layers of the mesenteriole of the vermiform process; (e) right colic, along the medial side of the ascending colon.
The Mesocolic Glands (lymphoglandulæ mesocolicæ) are numerous, and lie between the layers of the transverse mesocolon, in close relation to the transverse colon; they are best developed in the neighborhood of the right and left colic flexures. One or two small glands are occasionally seen along the trunk of the right colic artery and others are found in relation to the trunk and branches of the middle colic artery.
