	[[:File:Keibel Mall 2 ~~576~~.jpg\|Fig. ~~576~~.]] Reconstruction of the ~~lower end of the body of~~ a human embryo of 5.3 mm ~~greatest length 4~~.~~6 mm nape length, and with 36 pairs of primitive segments. (Embryo 1420,~~ from the ~~collection of Professor Keibel~~, ~~Freiburg i. Br.) The primary excretory duct has come to lie between the~~ visceral and ~~the~~ parietal ~~roots of the a~~. umbilicalis. At the level of its opening into the bladder it bends at a right angle and at the bend it pushes out the ureter bud stages of the development of the ureter. The hemispherical ureteric anlage is not exactly in the middle of the dorsal wall of the primary duct, but inclines more and more towards its medial surface, the degree of inclination varying in different embryos. When the anlage later elongates to form a canal it always lies at the middle of the dorsal surface of primary duct and, later on, ~~even on its lateral surface, yet in an embryo of 7.8 mm. greatest length it still opened distinctly on the medial surface~~.		[[:File:Keibel Mall 2 449.jpg\|Fig. 449.]] Reconstruction of the a. umbilicalis in a human embryo 5.3 mm long. The umbilical artery is seen to arise from the aorta by three roots, a visceral and two parietal. (After Felix, 1910.)

[[:File:Keibel Mall 2 570.jpg\|Fig. 570.]] Transverse section of the right mesonephros of a human embryo of 5.3 mm. greatest length and 4.6 mm. nape length. (slide 11, row 4, section 1.) A mesonephric artery is cut almost throughout its entire length; the middle portion on account of a curve does not fall within the plane of the section. The artery ends in a spherical enlargement within a Malpighian corpuscle.
