In this terracotta teaching model, the cervix is completely dilated, while the external uterine orifice is still closed and the membranes are intact. The placenta is in fundal position. The fetus is in cephalic presentation. We can observe the umbilical cord winding around the neck and the superior left limb. Here (as in items XVIII.9 - XVIII.10 - XVIII.11 - XVIII.12) we can observe the typical or normal attitudes of the fetus inside the uterus, such as head bent forward, lower joints flexed, arms folded on chest or lodged in the crook between head and thorax. Thanks to this crouching position, recognizable from the start of fetal development, the fetus acquires a near-oval shape and occupies about half the length that it would in an extended position. The model was commissioned by Giuseppe Galletti.
