Raissa Nitabuch

Raissa Nitabuch (born 1859) was a Russian pathologist who is known for her histological studies of the human placenta. The layer of fibrin that was thought to separate the uterine decidua from the fetoplacental trophoblast after birth was named the Nitabuch layer or Nitabuch membrane, thus becoming the only woman whose name is "affiliated with a macroscopic anatomical structure." She was also the first to describe the spiral arteries which connect the uterine and placental blood flow during pregnancy, providing the developing fetus with oxygen and nutrients.
