Human Female Fetus - Pelvic Region (10 week)

Large labelled image version of plane D, close to midline (Stain - Haematoxylin Eosin) 0.7 mm scale bar.

Genital Development

The genital tubercle can be seen at the top of the image and will contribute to the female external genitalia.

The early uterus forming from the paramesonephric duct lies in the peritoneal body cavity. Anterior to the uterus is the small uterovesical pouch (Dunn's pouch or pouch of Meiring), while posterior to the uterus is the larger rectouterine pouch (pouch of Douglas).

Renal Development

The urinary bladder, from the urogenital sinus that in turn developed from the cloaca, is surrounded by the developing detrusor muscle. A ureter and the allantois can be seen extending from the top of the bladder.

Gastrointestinal Development

Behind the developing uterus the rectum formed from hindgut is cut in longitudinal section.

Musculoskeletal Development

On the ventral body wall the inguinal cone lies beneath the midgut herniation and beneath this is the pubic symphysis of the developing pelvis. Behind the rectum the vertebral column and intervertebral disc reigns can be seen. Note the vertebral bodies are cartilage and will ossify during the fetal period.
