The fourth type is merely an exaggerated condition of the third; the right saccule is still larger, and at the same time the left saccule has become atrophied, so that the original apex of the cecum, with the vermiform process, is close to the ileocolic junction, and the anterior band courses medialward to the same situation.
In consequence of this an apparently new apex has been formed by the growing downward of the right saccule, and the original apex, with the appendix attached, is pushed over to the left toward the ileocolic junction.
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.
In early fetal life it is short, conical, and broad at the base, with its apex turned upward and medialward toward the ileocolic junction.
They unite to form three or four vessels, which end partly in the lower and partly in the upper glands of the ileocolic chain.
The anterior vessels pass in front of the cecum, and end in the anterior ileocolic glands and in the upper and lower glands of the ileocolic chain; the posterior vessels ascend over the back of the cecum and terminate in the posterior ileocolic glands and in the lower glands of the ileocolic chain.
Besides the tributaries which correspond with the branches of the superior mesenteric artery, viz., the intestinal, ileocolic, right colic, and middle colic veins, the superior mesenteric vein is joined by the right gastroepiploic and pancreaticoduodenal veins.
At its origin the right ureter is usually covered by the descending part of the duodenum, and in its course downward lies to the right of the inferior vena cava, and is crossed by the right colic and ileocolic vessels, while near the superior aperture of the pelvis it passes behind the lower part of the mesentery and the terminal part of the ileum.
The superior mesenteric glands may be divided into three principal groups: mesenteric, ileocolic, and mesocolic.
There are three principal pouches or recesses in the neighborhood of the cecum (Figs. 1043 to 1045): (a) The superior ileocecal fossa is formed by a fold of peritoneum, arching over the branch of the ileocolic artery which supplies the ileocolic junction.
