Fig. 68.—Successive Stages in the Implantation of the Ovum of the Spermophile . a, syncytial knob; k, inner cell-mass.—(Rejsek.) of the central cells is almost completed (Fig. 68, A). At one region of the covering layer the cells become thicker and later form a syn- cytial projection or knob which comes into contact with the uterine mucosa (Fig. 68, B), and at the point of contact the mucosa cells undergo degeneration, allowing the knob to come into relation with the deeper tissues of the uterus (Fig. 68, C), the process apparently being one in which the mucosa cells are eroded by the syncytial knob. It seems probable that in the human ovum the process is at first of a similar nature and that as the covering layer cells come into.
