Chorion - The outermost membrane that helps form the placenta.

Corpus Luteum - Progesteron is normally secreted in relatively large quantities.

* The ischial spines are designated as an important landmark in labor & delivery because the distance between the spines is the narrowest diameter of the pelvis.

* The inner membrane that provides a fluid medium for the embryo is the AMNION.

* The Placenta DOES NOT produce FSH (Follicle Stimulation Hormone). (the anterior pituitary secretes FSH)

* After the first 3 months of pregnancy the chief source of estrogen and progesterone is the Placenta.
