Fig. 3. Coloured drawing of a section (slide 25-2) through the middle of the ovum

The ovum (Fig. 3) consists of a slightly flattened chorionic vesicle, the blastocyst, which has an internal measurement of 047mm. in the equatorial plane, i.e. from side to side, and of 0.28 mm. in the polar plane, i.e. from the surface inward. The inner surface of the blastocyst is smooth and has the embryonic rudiment attached at its base; the outer surface is irregular owing to cellular and syncytial processes growing out from it into the implantation cavity.
