Fig. 2. A human ovum of approximately 11 days of age

The endometrial epithelium has superficially repaired the defect made by the implanting ovum. The exocoelom (EX) is now a much more definite space and is bounded below by the primitive entoderm of the bilaminar embryonic disk. Elsewhere it is surrounded by the sharply delineated exocoelomic membrane. Note the multiple gossamer attachments of the membrane by mesoblastic cells to the surrounding trophoblast from which it originally arose. Carnegie 7699, 8-5-3, X100.
