| superior internal parietal artery | <anatomy, artery> The largest cortical branch of the pericallosal artery supplying the medial and superolateral surface of the parietal lobe posterior to the paracentral lobule; rarely does it extend to supply part of the occipital lobe. Synonym: arteria parieto-occipitalis, superior internal parietal artery. (05 Mar 2000) |

| superior parietal gyrus | The area of the convex surface of the parietal lobe of the cerebrum lying between the longitudinal fissure and the interparietal sulcus behind the posterior central gyrus; it is continuous with the precuneus on the medial aspect of the hemisphere. Synonym: lobulus parietalis superior, superior parietal gyrus. (05 Mar 2000) |

| aneurysm of sinus of Valsalva | A congenital thin-walled tubular out pouching usually in the right or non-coronary sinus with an entirely intracardiac course that may rupture into the right or rarely the left heart chambers to form an aortocardiac fistula. (05 Mar 2000) |
| aortic sinus | The space between the superior aspect of each cusp of the aortic valve and the dilated portion of the wall of the ascending aorta, immediately above each cusp. Synonym: sinus aortae, Petit's sinus, Valsalva's sinus. Arlt's sinus, an inconstant depression on the lower portion of the internal surface of the lacrimal sac. Barber's pilonidal sinus, pilonidal sinus occurring in barbers, usually in the web between the fingers, due to the burying of exogenous hairs by the alternate loosening and tightening of tissues of the hand by the manipulation of scissors. (05 Mar 2000) |
| aortic sinus aneurysm | Abnormal dilation of one or more of the three aortic sinuses situated behind the three aortic valve cusps. (05 Mar 2000) |
| apertura sinus frontalis | One of a pair of openings in the floor of the frontal sinuses in the nasal part of the frontal bone, through which the frontal sinuses communicate with the ethmoidal infundibulum via the frontonasal duct. Synonym: apertura sinus frontalis. (05 Mar 2000) |
| apertura sinus sphenoidalis | One of the pair of openings in the body of the sphenoid bone through which the sphenoid sinuses communicate with the sphenoethmoidal recess of the nasal cavity. Synonym: apertura sinus sphenoidalis, sphenoidal sinus aperture. (05 Mar 2000) |
