. The comparative anatomy of the domesticated animals. Veterinary anatomy. PERPENDICULAB^ECTIOIT THROUGH THE INTESTINAL WAUi TO SHOW A SOLITARY FOLLICLE. a, Liel)erkuliniaii glands; 6, Solitary follicle; c, Lacteal vessels surrounding, but not penetrating^ the follicles; d, Large efferent vessels, provided with valves. Fig. 201. moderately-thick external capsule, having no excretory canal, and containing a similar secretion to that in the solitary follicles. They are surrounded by a zone or band of simple follicles, and the spaces between them are covered with villi. The vesicles are usually closed; though it is supposed they open at intervals to discharge their secretion. The mucous and submucous coats of the intestine are intimately adherent and highly vascular, oppo- site the Peyerian glands.) 4. Vessels and nerves,—The small intestine receives its arteries almost exclusively from the great mesenteric artery. One, which goes to the duodenum, comes from the coeliac trunk. These arteries form a submucous network, from which branches pass inwards and outwards, the first to the muscular and serous tunics, the second to the glands and the villi. A tubular network sur- rounds each Lieberkiihnian gland, and is observed in each villus ; while a spherical reticulation sur- rounds each solitary follicle, loops being-given off villi op intestine, with which penetrate nearly to the centre of the ™^,if'*'^''^'^^ ^''^''''' follicle. The veins have the same arrangement, and finally enter the vena portae. 29.
