Organisms that possess this organ also have an fibular malleolus and a mortise-tenon upper ankle joint.
Organisms that possess this organ also have an fibular malleolus and a mortise-tenon upper ankle joint. This organ comes in zonary and cotyledonary varieties. The paternal X chromosome is always inactivated in this tissue, which expresses HLA-E, HLA-F, and HLA-G rather than more canonical types of MHC molecules. This organ expresses neurokinin B, rendering it immunologically privileged. ToRCH pathogens are capable of crossing it, and infections in this organ can cause proliferation of Hofbauer cells. Improper attachment of this organ can result in a condition known as this organ's previa. The first hormone secreted by this structure, hCG, is detectable shortly after implantation occurs. For 10 points, name this structure which provides gas exchange and nutrients to the developing fetus.
