| inferior temporal gyrus | 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) |

| isthmus of cingulate gyrus | The narrowing of the cingulate gyrus, at its transition with the hippocampal gyrus behind and below the splenium of the corpus callosum, caused by the anterior extension of the conjoined parieto-occipital and calcarine sulci. Synonym: isthmus gyri cinguli, isthmus of gyrus fornicatus, isthmus of limbic lobe. (05 Mar 2000) |
| isthmus of gyrus fornicatus | The narrowing of the cingulate gyrus, at its transition with the hippocampal gyrus behind and below the splenium of the corpus callosum, caused by the anterior extension of the conjoined parieto-occipital and calcarine sulci. Synonym: isthmus gyri cinguli, isthmus of gyrus fornicatus, isthmus of limbic lobe. (05 Mar 2000) |
| tail of dentate gyrus | A slender whitish band, the attenuated anterior continuation of the dentate gyrus (fascia dentata), crossing transversally the surface of the recurved part of the uncus gyri parahippocampalis. Synonym: band of Giacomini, cauda fasciae dentatae, frenulum of Giacomini, tail of dentate gyrus. (05 Mar 2000) |
| transitional gyrus | A small convolution connecting two lobes or two main gyri in the depth of a sulcus. Synonym: annectent gyrus, transitional convolution. (05 Mar 2000) |
| uncinate gyrus | Origin: L. <zoology> A hook or claw. Source: Websters Dictionary (01 Mar 1998) |
| fasciolar gyrus | A small paired band that passes around the splenium of the corpus callosum from the lateral longitudinal stria to the dentate gyrus. Synonym: gyrus fasciolaris, fascia cinerea, fasciola cinerea. (05 Mar 2000) |
| fornicate gyrus | The horseshoe-shaped cortical convolution bordering the hilus of the cerebral hemisphere; its upper limb is formed by the cingulate gyrus, its lower by the parahippocampal gyrus. Synonym: gyrus fornicatus. (05 Mar 2000) |
| lateral occipitotemporal gyrus | An extremely long convolution extending lengthwise over the inferior aspect of the temporal and occipital lobes, demarcated medially by the collateral sulcus from the lingual gyrus and the anterior part of the parahippocampal gyrus, laterally by the inferior temporal sulcus from the inferior temporal gyrus. Synonym: gyrus occipitotemporalis lateralis, gyrus fusiformis, lateral occipitotemporal gyrus, lobulus fusiformis. (05 Mar 2000) |
| fusiform gyrus | An extremely long convolution extending lengthwise over the inferior aspect of the temporal and occipital lobes, demarcated medially by the collateral sulcus from the lingual gyrus and the anterior part of the parahippocampal gyrus, laterally by the inferior temporal sulcus from the inferior temporal gyrus. Synonym: gyrus occipitotemporalis lateralis, gyrus fusiformis, lateral occipitotemporal gyrus, lobulus fusiformis. (05 Mar 2000) |
| lingual gyrus | A relatively short horizontal convolution on the inferomedial aspect of the occipital and temporal lobes, demarcated from the lateral occipitotemporal or fusiform gyrus by the deep collateral sulcus, from the cuneus by the calcarine sulcus; its anterior extreme abuts the isthmus of the parahippocampal gyrus; the medial or upper strip of the gyrus forming the lower bank of the calcarine sulcus corresponds to the inferior half of the striate area or primary visual cortex and represents the contralateral upper quadrant of the binocular field of vision. Synonym: gyrus lingualis, gyrus occipitotemporalis medialis, medial occipitotemporal gyrus. (05 Mar 2000) |
| long gyrus of insula | The most posterior and longest of the slender straight gyri that compose the insula. Synonym: gyrus longus insulae. (05 Mar 2000) |
| aditus glottidis superior | Portion of the cavity of the larynx between the vestibular and vocal folds, with which the ventricles communicate. Synonym: aditus glottidis superior. (05 Mar 2000) |
| angulus superior scapulae | Formerly named the medial angle, it lies at the junction of the superior and medial borders of the bone. Synonym: angulus superior scapulae. (05 Mar 2000) |
| ankyloglossia superior syndrome | <syndrome> A congenital condition in which the tongue adheres to the hard palate; no evidence of genetic factors. (05 Mar 2000) |
