Shape.—In gen- eral the body of the uterus is cylindrical and divides in front into two branches. Each branch con- nects with a Fallo- pian tube and through that with the ovary. The body of the uterus narrows behind to a neck which pro- jects into the va- gina except in the sow. The cervix (neck), body and horns differ greatly in the various domestic animals, the cervix in the cow is from two to three inches long, very firm and with a tortuous canal. The sow has the body of the uterus short, horns long and the cervix not very distinct, the vagina and uterus being more nearly continuous. The rectum is above the uterus, and the bladder below it. Supports.—The uterus is held in place by four ligaments which are partly folds of the peritoneum. The most important of these are the broad ligaments. These are two wide folds of the peritoneum with some fibrous and muscular tissue, which are attached to the body of the uterus and its horns, one on each side and to the sublumbar region above. A third liga- ment is attached above to the rectum, and a fourth below to the. Fig. 88.—Fetus and Fetal Membranes of the Cow at Mid-pregnancy.
