The =uterus= is a hollow muscular organ, which receives the Fallopian
tubes anteriorly and opens into the vagina posteriorly. It is situated
chiefly in the abdominal cavity, but extends a short distance into the
pelvic cavity. It is attached to the lumbar wall of the abdomen and the
lateral walls of the pelvic cavity by two folds of peritoneum termed the
broad ligaments. It consists of two cornua or horns, the body, and the
neck.
The =cornua= or =horns= of the uterus (Cornua uteri) are situated
entirely in the abdomen. They appear to vary considerably in position;
commonly they are pressed up against the sublumbar muscles by the
intestine (left portions of large colon, small colon, and small
intestine). They are cylindrical, and are about ten inches (ca. 25 cm.)
in length. The anterior extremity of each forms a blunt point which
receives the Fallopian tube. Posteriorly they increase somewhat in
caliber, converge, and unite with the body. The =dorsal= (or attached)
=border= is slightly concave and is attached to the broad ligament. The
=ventral border= is convex and free.
