| tenia choroidea | The somewhat thickened line along which a choroid membrane or plexus is attached to the rim of a brain ventricle. Synonym: tenia telae. Teniae coli, the three bands in which the longitudinal muscular fibres of the large intestine, except the rectum, are collected; these are the mesocolic tenia, situated at the place corresponding to the mesenteric attachment; the free tenia, opposite the mesocolic tenia; and the omental tenia, at the place corresponding to the site of adhesion of the greater omentum to the transverse colon. Synonym: bands of colon, colic teniae, teniae of Valsalva. (05 Mar 2000) |
| tenia fimbriae | The line of attachment of the choroid plexus of the lateral ventricle to the fornix. Synonym: tenia fimbriae, tenia of the fornix. (05 Mar 2000) |
| tenia fornicis | The line of attachment of the choroid plexus of the lateral ventricle to the fornix. Synonym: tenia fimbriae, tenia of the fornix. (05 Mar 2000) |
| tenia hippocampi | A narrow sharp-edged crest of white fibre matter, continuous with the alveus hippocampi, attached to the medial border of the hippocampus; composed of efferent fibres of the hippocampus that form the fornix, fibres of the hippocampal commissure, and septohippocampal fibres. Synonym: corpus fimbriatum, tenia hippocampi. (05 Mar 2000) |
| tenia libera | See: teniae coli. Synonym: tenia libera. (05 Mar 2000) |
| tenia mesocolica | See: teniae coli. Synonym: tenia mesocolica. (05 Mar 2000) |
| tenia of the fornix | The line of attachment of the choroid plexus of the lateral ventricle to the fornix. Synonym: tenia fimbriae, tenia of the fornix. (05 Mar 2000) |
| tenia omentalis | See: teniae coli. Synonym: tenia omentalis. (05 Mar 2000) |
| tenia saemicircularis | A slender, compact fibre bundle that connects the amygdala (amygdaloid body) with the hypothalamus and other basal forebrain regions. Originating from the amygdala, the bundle passes first caudalward in the roof of the temporal horn of the lateral ventricle; it follows the medial side of the caudate nucleus forward in the floor of the ventricle's central part (or body) until it reaches the interventricular foramen, in the posterior wall of which it curves steeply down to enter the hypothalamus, with fibres passing both rostral and caudal to the anterior commissure. Coursing caudalward in the medial part of the hypothalamus, the bundle terminates in the anterior and ventromedial hypothalamic nuclei. Synonym: stria terminalis, Foville's fasciculus, Tarin's tenia, tenia saemicircularis. (05 Mar 2000) |
| tenia tecta | See: indusium griseum. (05 Mar 2000) |
| tenia telae | The somewhat thickened line along which a choroid membrane or plexus is attached to the rim of a brain ventricle. Synonym: tenia telae. Teniae coli, the three bands in which the longitudinal muscular fibres of the large intestine, except the rectum, are collected; these are the mesocolic tenia, situated at the place corresponding to the mesenteric attachment; the free tenia, opposite the mesocolic tenia; and the omental tenia, at the place corresponding to the site of adhesion of the greater omentum to the transverse colon. Synonym: bands of colon, colic teniae, teniae of Valsalva. (05 Mar 2000) |
| tenia terminalis | A vertical crest on the interior wall of the right atrium that lies to the right of the sinus of the vena cava and separates this from the remainder of the right atrium. Synonym: tenia terminalis, terminal crest. (05 Mar 2000) |
| tenia thalami | The sharp edge or angle between the superior and medial surface of the thalamus on either side; to it is attached the epithelial lamina forming the roof of the third ventricle. Synonym: tenia ventriculi tertii, thalamic tenia. (05 Mar 2000) |
| tenia ventriculi quarti | The line of attachment of the choroid roof to the rim of the fourth ventricle. Synonym: tenia of fourth ventricle. (05 Mar 2000) |
