amnio-

The amnion.

[Greek amnion, caul, a diminutive of amnos, lamb.]

The amnion is the innermost membrane that encloses the embryo of a mammal, bird, or reptile, for which the adjective is amniotic. Amniocentesis is the process of sampling that fluid for analysis. Related medical terms include amniotomy (Greek -tomia, cutting), the artificial rupture of the amnion immediately before birth, and amnionitis, an inflammation of the amnion that may be caused by premature rupture of the membrane.
