Located or occurring outside the placenta, the organ that connects a developing baby to the mother during pregnancy.
From Latin 'extra' (outside) + 'placenta' (from Latin 'placenta', meaning cake, referring to the flat organ). The term combined in modern medical language to describe anatomical structures beyond the placental tissue.
Doctors use this term to distinguish between problems in the placenta itself versus problems in nearby tissues—it's crucial for diagnosing pregnancy complications and understanding why some babies develop differently.
