Abstract
A human embryo obtained incidentally from a hysterectomy specimen of a 36 year old
woman who was operated for chronic pelvic inflammatory disease, was aerially sectioned
and reconstructed with 104 section slides.
This embryo was characterized by a thick corneal body with well developed
Descemet's endothelium, the optic nerve having vascular canal, the cochlear turning a
little more than one time, the hypophysis with threadlike stalk, the vomeronasal organ
having intermediate long narrow canal, the submandibular gland with deep lumen, the
kidney with short secretory tubules and few large glomeruli and a well formed osseous
band in the cartilage and bone.
From above findings, it was concluded that this embryo belongs to the age group Ⅹ
ⅩⅢ of Streeter's developmental horizon.
