Fig. 2 Sagittal section of head end of a ten-day rabbit embryo

(27D) showing oral membrane intact. X 50. Nasal end at right. 10. p. inf., primitive infundibulum; R, Rathke’s pouch; or. pl.., oral plate; S., Seessel’s pouch; nc., notochord.

Figure 2 presents a sagittal section of a timed ten—day embryo (27D). It is slightly older than the preceding, but the oral membrane is still unbroken. A comparatively large evagination of the brain wall is seen dorsal to Rathke’s pocket. This corresponds to the ‘primitive Trichter’ of Mihalkovics. In this embryo the extremity of the notochord is in close contact with the wall of hypophysis anlage.
