pararectal

The inferior mesenteric glands (Fig. 617) consist of: (a) small glands on the branches of the left colic and sigmoid arteries; (b) a group in the sigmoid mesocolon, around the superior hemorrhoidal artery; and (c) a pararectal group in contact with the muscular coat of the rectum.

On the peritoneum between the paravesical and pararectal fossæ the only elevations are those produced by the ureters and the hypogastric vessels. (b) In the female, pararectal and paravesical fossæ similar to those in the male are present: the lateral limit of the paravesical fossa is the peritoneum investing the round ligament of the uterus.

It then leaves the sides and, finally, the front of the rectum, and is continued on to the upper ends of the seminal vesicles and the bladder; on either side of the rectum it forms a fossa, the pararectal fossa, which varies in size with the distension of the rectum.

—The lymphatics from the anus pass forward and end with those of the integument of the perineum and scrotum in the superficial inguinal glands; those from the anal canal accompany the middle and inferior hemorrhoidal arteries, and end in the hypogastric glands; while the vessels from the rectum traverse the pararectal glands and pass to those in the sigmoid mesocolon; the efferents of the latter terminate in the preaortic glands around the origin of the inferior mesenteric artery.
