Fig. 554c. Transverse sections through a human embryo of 30 mm trunk length

554a | 554b | 554c

(Embryo R. Meyer 273, from the collection of Professor Meyer, Berlin; slide 11, row 4, section 2; slide 13, row 5, section 2; slide 14, row 5, section 2.)

The three sections show the formation of the genital cord. The legends have been arranged so that different structures are indicated in each section and the reader should first study the legends in all three figures.

c. The two mesonephric folds have united in the middle line to form the genital cord. By this and the two inguinal folds the body cavity is divided into four parts, — the excavatio recto-uterina between the posterior body wall and the genital cord; a space between the genital cord, the posterior wall of the bladder and the inguinal folds, from which the excavat,io vesico-uterina and the medial part of the saccus vaginalis (see section on descensus) are formed; and two lateral spaces between the plica inguinalis and the lateral abdominal wall, which become the lateral part of the saccus vaginalis.
