pelvic outlet the inferior opening of the pelvis minor.
the lower opening of the true pelvis, bounded anteriorly by the pubic arch, laterally by the rami of the ischium and the sacrotuberous ligament on either side, and posteriorly by these ligaments and the tip of the coccyx.
the space surrounded by the bones of the lower part of the true pelvis. In men the shape of the pelvic outlet is narrower than that in women, but this is of no clinical significance. In women the shape and size of the pelvis vary and are of importance in childbirth. The shapes are classified by the length of the diameters as compared with each other and by the thickness of the bones. The diameters of the outlet are the anteroposterior, from the symphysis pubis to the coccyx, and the intertuberous, laterally from one to the other ischial tuberosity. See also pelvic classification.
pertaining to the pelvis.
commonest in horses as a result of a rectal tear during a manual examination. The tear is only mucosa deep and the infection is deposited in the pelvic fascia where an abscess develops. This has the potential to erode into the peritoneal cavity. The syndrome begins as a toxemia and fever caused by the local abscess but a common sequel is the abrupt appearance of severe abdominal pain and toxemic shock.
os coxae, comprising the ilium, ischium and pubis. See also Table 10.
the canal from the pelvic inlet to the pelvic outlet.
the space bounded by the bones of the pelvis.
the bony ring formed by the pair of hip bones fused at the symphysis and their firm articulation with the sacrum, and in some species one or two coccygeal vertebrae.
the cranial opening of the pelvis.
pelvic intestinal hernia

include the dorsal sacroiliac, the sacrotuberal and the iliolumbar ligaments.
see Table 14.
includes reproductive organs, urinary bladder, ureter, rectum.
the caudal opening of the pelvis, guarded by the pelvic diaphragm.
the autonomic plexus that is distributed to the pelvic viscera that consists of the cranial vesical plexus, the middle genital plexus and the caudal hemorrhoidal plexus, located on the ventrolateral surface of the rectum. It innervates the urinary bladder, prostate, ductus deferens and cranial urethra. It is supplied by the hypogastric and pelvic splanchnic nerves.

surgical separation of the symphysis in immature animals as an aid in dystocia due to maternal pelvic inadequacy.
that part of the urethra that passes through the pelvis.
includes urinary bladder and pelvic ureters and urethra, rectum, prostate, seminal vesicles, vas deferens and ampullae in males, and vagina cervix and uterus, possibly ovaries, in the female.
