| lobus superior pulmonis | The lobe of the right lung that lies above the oblique and horizontal fissures and includes the apical, posterior and anterior bronchopulmonary segments; in the left lung, the lobe lies above the oblique fissure and contains the apicoposterior, anterior, superior lingular and inferior lingular segments. Synonym: lobus superior pulmonis, upper lobe of lung. (05 Mar 2000) |

| angulus occipitalis ossis parietalis | An angle formed by the junction, at the opisthion, of lines coming from the basion and from the projection in the median plane of the lower border of the orbits. See: Daubenton's line, Daubenton's plane. Synonym: angulus occipitalis ossis parietalis, occipital angle of parietal bone. (05 Mar 2000) |
