Abstract
A human embryo that is thought to belong to age
group XVII of Streeter’ s developmental horizon is
described and reported. This embryo was obtained
incidentally from the hysterectomy specimen. It was
serially sectioned and was reconstructed with the 643
section slides
The length of the embryo was llmm. This embryo
was characterized by the formation of pituitary, for'
mation of one semicircular duct at the inner ear,thin
lens vesicle. marked pigmentation of the retina,
complete separation of the right and left atrioventric'
비a r canals , formation of the semilunar valves, incom
plete interventricular septum, and the separation of
aorta and pulmonary artery. The gonad was undiffe·
rentiated and Muellerian duct was not observed
From the above findings, we concluded that this
