Fig. 418. Median sagittal dissection of a 35 mm Embryo

original x4

Median Sagittal Section (Fig. 418). - New features of the brain are the olfactory lobes, the chorioid plexus of the third and lateral ventricles, the thalami, the epiphysis, and consolidated hypophysis. The primitive mouth cavity is now divided by the palatine folds into upper nasal passages and lower oral cavity. Of the viscera, the distinct genital and suprarenal glands and the enlarged metanephros command attention, as does the coiling of the intestine. The ureter has acquired a separate opening at the base of the bladder, and the urethra may be traced into the phallus.
