What is the Shape of the body of uterus ?

The uterus is pyriform or pear shaped in shape. It is about 7.5 cm long, 5 cm broad, and 2.5 cm thick. It weighs 30 to 40 grams. It is divisible into an upper expanded pa called the body and a lower cylindrical pa called the cervix. The junction of these two pas is marked by a circular constriction called Isthmus. The body forms the upper two-thirds of the organ, and the cervix forms the lower one-third. Ref : B D Chaurasia's Human Anatomy, Seventh Edition , volume 2 , pg.no., 419
