Synonym: vena umbilicalis sinistra. (05 Mar 2000) |
| amniotic fold | A fold of amniotic membrane enclosing the yolk stalk and extending from the point of insertion of the umbilical cord to the yolk sac; in reptiles and birds it is the reflected edge of the amnion where it folds over to cover the embryo during early development. Synonym: Schultze's fold. (05 Mar 2000) |

| aryepiglottic fold | A prominent fold of mucous membrane stretching between the lateral margin of the epiglottis and the arytenoid cartilage on either side; it encloses the aryepiglottic muscle. Synonym: plica aryepiglottica. (05 Mar 2000) |

The normal Asian eyefold is continuous with the lower edge of the upper eyelid and actually appears distinctly different than a true epicanthal fold. (12 Dec 1998) |
