| musculus obliquus capitis superior | <anatomy, muscle> Origin, transverse process of atlas; insertion, lateral third of inferior nuchal line; action, rotates head; nerve supply, suboccipital. See: suboccipital muscles. Synonym: musculus obliquus capitis superior, superior oblique muscle of head. (05 Mar 2000) |
| musculus obliquus superior | <anatomy, muscle> Origin, above the medial margin of the optic canal; insertion, by a tendon passing through the trochlea, or pulley, and then reflected backward, downward, and laterally to the sclera between the superior and lateral recti; action, primary, intorsion; secondary, depression and abduction; nerve supply, trochlear nerve.

| posterior branch of superior thyroid artery | <anatomy, artery> Branch of superior thyroid artery which descends to supply the apical portion of the ipsilateral lobe of the thyroid, continuing along the posterior border of the gland to anastomose with the inferior thyroid artery. Synonym: ramus posterior arteriae thyroideae superioris. (05 Mar 2000) |
| posterior superior alveolar artery | <anatomy, artery> Origin, 3rd part of maxillary artery within pterygopalatine fossa; distribution, molar and premolar teeth, gingiva and mucous membrane of maxillary sinus.
