Fig. 6. Sections through developing fourth pouch of human embryos

To show relationship between “ventral component ” of this pouch and the differentiating thyroid tissue. (x 450.)

(a) Left side 13 mm. human embryo

(b) Right side 17 mm. human embryo;

(c) Left side 17 mm. human embryo

(a') Left side 19 mm. human embryo.

Note different appearance presented by the “ventral component” of the fourth pouch. In (b) and (c) it appears to be more intimately related to median thyroid tissue than in the other sections.
