cingulum

 [sing´gu-lum] (pl. cin´gula) (L.)
1. an encircling part or structure; a girdle.
2. a bundle of association fibers partly encircling the corpus callosum not far from the median plane, interrelating the cingulate and hippocampal gyri.
3. the lingual lobe of an anterior tooth. adj., adj cing´ulate.

cin·gu·la

(sin'gyū-lŭm, -lē, -lă), [TA]
1. Synonym(s): girdle
2. A well-marked fiber bundle passing longitudinally in the white matter of the cingulate gyrus; the bundle extends from the region of the anterior perforated substance back over the superior surface of the corpus callosum; behind the latter's splenium it curves down and then forward in the white matter of the parahippocampal gyrus; largely composed of fibers from the anterior thalamic nucleus to the cingulate and parahippocampal gyri, it also contains association fibers connecting these gyri with the frontal cortex, and their various subdivisions with each other.
[L. girdle, fr. cingo, to surround]

2. A well-marked fiber bundle passing longitudinally in the white matter of the cingulate gyrus; the bundle extends from the region of the anterior perforated substance back over the dorsal surface of the corpus callosum; behind the splenium of the latter it curves down and then forward in the white matter of the parahippocampal gyrus; composed largely of fibers from the anterior thalamic nucleus to the cingulate and parahippocampal gyri, it also contains association fibers connecting these gyri with the frontal cortex, and their various subdivisions with each other.
3. The lingual portion of an incisor or canine tooth, which forms a convexity on the cervical third of the crown.
4. The cervical third of the crown of a molar, which is the source of the developing cusps.
