| supramarginal convolution | A folded convolution capping the posterior extremity of the lateral (sylvian) sulcus; together with the angular gyrus, it forms the inferior half of the parietal lobe. Synonym: gyrus supramarginalis, supramarginal convolution. (05 Mar 2000) |
|---|---|
| inferior temporal convolution | A sagittal convolution on the inferolateral border of the temporal lobe of the cerebrum, separated from the middle temporal gyrus by the inferior temporal sulcus. On the inferior surface of the temporal lobe it is separated from the medial occipitotemporal gyrus by the occipitotemporal sulcus. It includes the lateral occipitotemporal gyrus. Synonym: gyrus temporalis inferior, inferior temporal convolution, third temporal convolution. (05 Mar 2000) |
| third temporal convolution | A sagittal convolution on the inferolateral border of the temporal lobe of the cerebrum, separated from the middle temporal gyrus by the inferior temporal sulcus. On the inferior surface of the temporal lobe it is separated from the medial occipitotemporal gyrus by the occipitotemporal sulcus. It includes the lateral occipitotemporal gyrus. Synonym: gyrus temporalis inferior, inferior temporal convolution, third temporal convolution. (05 Mar 2000) |
| transitional convolution | A small convolution connecting two lobes or two main gyri in the depth of a sulcus. Synonym: annectent gyrus, transitional convolution. (05 Mar 2000) |
| Zuckerkandl's convolution | A slender vertical whitish band immediately anterior to the lamina terminalis and anterior commissure; contrary to its name, it is not a cortical convolution but is the ventral continuation of the transparent septum. Synonym: area subcallosa, gyrus paraterminalis, gyrus subcallosus, pedunculus corporis callosi, corpus paraterminale, paraterminal body, paraterminal gyrus, peduncle of corpus callosum, precommissural septal area, subcallosal area, Zuckerkandl's convolution. (05 Mar 2000) |
| first temporal convolution | A longitudinal gyrus on the lateral surface of the temporal lobe between the lateral (sylvian) fissure and the superior temporal sulcus. Synonym: gyrus temporalis superior, first temporal convolution, superior temporal convolution. (05 Mar 2000) |
| acute ascending paralysis | A paralysis of rapid course beginning in the legs and involving progressively the trunk, arms, and neck, ending sometimes in death in from one to three weeks. Synonym: ascending paralysis. (05 Mar 2000) |
| ascending | Rising or curving upward. <botany> Growing erect after an oblique or semi-horizontal beginning. (09 Oct 1997) |
| ascending anterior branch | The ascending anterior branch of the superior lobar branches of the left and right pulmonary arteries. Synonym: ramus anterior ascendens. (05 Mar 2000) |
| ascending aorta | The part of the aorta prior to the aortic arch from which arise the coronary arteries. Synonym: aorta ascendens, ascending part of aorta, pars ascendens aortae. (05 Mar 2000) |
| ascending artery | <anatomy, artery> The branch of the inferior branch of the ileocolic artery that passes superiorly up the ascending colon to communicate with a branch of the right colic artery and supplying the ascending colon. Synonym: arteria ascendens. (05 Mar 2000) |
| ascending branch | A branch directed superiorly. Nomina Anatomica recognises the ascending branch of the following: 1) deep circumflex iliac artery; 2) lateral cerebral sulcus; 3) lateral circumflex femoral artery. Synonym: ramus ascendens. (05 Mar 2000) |
| ascending branch of the inferior mesenteric artery | <anatomy, artery> Branch of the left colic artery (from inferior mesenteric artery) that passes anteriorly to the left kidney into the transverse mesocolon, where it anastomoses with the middle colic artery. It thus forms an anastomosis between superior and inferior mesenteric arteries, and is a component of the marginal artery (Drummond) of the colon. Synonym: arteria ascendens, arteria intermesenterica. (05 Mar 2000) |
| ascending cervical artery | <anatomy, artery> Origin, usually a terminal branch of the thyrocervical trunk (along with interior thyroid artery); distribution, muscles of neck and spinal cord; anastomoses, branches of vertebral, occipital, ascending pharyngeal, and deep cervical. Synonym: arteria cervicalis ascendens, cervicalis ascendens. (05 Mar 2000) |
| ascending cholangitis | Low-grade bacterial infection of the biliary tract; sometimes a cause of fever of unknown origin. Synonym: ascending cholangitis. (05 Mar 2000) |
