prominence

/prom·i·nence/ (prom´ĭ-nins) a protrusion or projection.
frontonasal prominence  frontonasal process; an expansive facial process in the embryo that develops into the forehead and bridge of the nose.
laryngeal prominence  Adam's apple; a subcutaneous prominence on the front of the neck produced by the thyroid cartilage of the larynx.
mandibular prominence  mandibular process; the ventral prominence formed by bifurcation of the mandibular (first pharyngeal) arch in the embryo, which unites ventrally with its fellow to form the lower jaw.
maxillary prominence  maxillary process; the dorsal prominence formed by bifurcation of the mandibular (first pharyngeal) arch in the embryo, which joins with the ipsilateral medial nasal prominence in the formation of the upper jaw.
nasal prominence, lateral  the more lateral of the two limbs of a horseshoe-shaped elevation in the future nasal region of the embryo; it participates in formation of the side and wing of the nose.
nasal prominence, medial  the more central of the two limbs of a horseshoe-shaped elevation in the future nasal region of the embryo; it joins with the ipsilateral maxillary prominence in the formation of half of the upper jaw.
