| anterior axillary fold | Bounds axilla anteriorly; formed by skin and fascia overlying inferior border of pectoralis major muscle. (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) |
| axillary fold | One of the folds of skin and muscular tissue bounding the axilla anteriorly and posteriorly. Synonym: plica axillaris. (05 Mar 2000) |
| palpebronasal fold | A fold of skin that comes down across the inner angle of the eye. The epicanthal fold is more common in children with Down syndrome and other birth defects than normal children and so is of value in diagnosis. Although some dictionaries state that this eye fold is found in peoples of Asian origin, this is not true. 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) |
| vascular fold of the caecum | <anatomy> A peritoneal fold that arches over a branch of the ileocolic artery and bounds in front a narrow recess, the superior ileocaecal (or ileocolic) recess. Synonym: plica caecalis vascularis. (05 Mar 2000) |

| Vater's fold | A fold of mucous membrane in the duodenum just above the greater duodenal papilla. (05 Mar 2000) |
| mallear fold | One of two ligamentous bands, anterior and posterior, making folds on the tympanic side of the tympanic membrane extending from each extremity of the tympanic notch to the malleolar prominence; they mark the boundary between the tense and the flaccid portions of the tympanic membrane. Synonym: plica mallearis, plica membranae tympani, Troltsch's fold. (05 Mar 2000) |
| mammary fold | Bandlike thickening of ectoderm in the embryo extending on either side from just below the axilla to the inguinal region; in human embryos, the mammary glands arise from primordia in the thoracic part of the ridge, the balance of the ridge disappearing; in some lower mammals which give birth to a litter of young, several milk glands develop along these lines. Synonym: mammary fold, milk line, milk ridge. (05 Mar 2000) |
| paraduodenal fold | A sickle-shaped fold of peritoneum sometimes found arching between the left side of the duodenojejunal flexure and the medial border of the left kidney; its right free edge contains the ascending branch of the left colic artery and inferior mesenteric vein; forms anterior boundary of the paraduodenal recess. See: paraduodenal recess. Synonym: plica paraduodenalis, Treitz's arch. (05 Mar 2000) |
| ventricular fold | One of the pair of folds of mucous membrane stretching across the laryngeal cavity from the angle of the thyroid cartilage to the arytenoid cartilage; they enclose a space called the rima vestibuli or false glottis. Synonym: plica vestibularis, false vocal cord, plica ventricularis, ventricular band of larynx, ventricular fold. (05 Mar 2000) |
| genital fold | One of the paired longitudinal ridge's developing in the dorsal body wall of the embryo on either side of the dorsal mesentery; the ridge is formed at first by the growing mesonephros and later by the mesonephros and the gonad. Synonym: genital fold, wolffian ridge. (05 Mar 2000) |
| rectouterine fold | A fold of peritoneum, containing the rectouterine muscle, passing from the sacrum to the base of the broad ligament on either side, forming the lateral boundary of the rectouterine (Douglas') pouch. Synonym: plica rectouterina, Douglas' fold, Jarjavay's ligament, Petit's ligament, rectouterine fold, uterosacral ligament. (05 Mar 2000) |
| rectovesical fold | The fold of peritoneum in the male that bounds the rectovesical pouch laterally. Synonym: rectovesical fold. (05 Mar 2000) |
| vestibular fold | One of the pair of folds of mucous membrane stretching across the laryngeal cavity from the angle of the thyroid cartilage to the arytenoid cartilage; they enclose a space called the rima vestibuli or false glottis. Synonym: plica vestibularis, false vocal cord, plica ventricularis, ventricular band of larynx, ventricular fold. (05 Mar 2000) |
