A. A 3.5 mm. embryo possessing 13 somites and representing the middle part of the fourth week of development. The amnion has been removed so that the approximation of the bodystalk and omphalo-mesenteric duct are less evident than in Fig. 11. This embryo is apparently a little longer than its developmental age would allow because its natural curvature is less, perhaps from having had the amnion removed.

Fig. 10A. Human 3.5 mm embryo possessing 13 somites

A 3.5 mm. embryo possessing 13 somites and representing the middle part of the fourth week of development. The amnion has been removed so that the approximation of the bodystalk and omphalo-mesenteric duct are less evident than in Fig. 11. This embryo is apparently a little longer than its developmental age would allow because its natural curvature is less, perhaps from having had the amnion removed. Carnegie 6344, sequence 4, X15.
