| stria | 1. A streak or line. 2. A narrow bandlike structure, a general term for such longitudinal collections of nerve fibres in the brain. Origin: L. = a furrow, groove (18 Nov 1997) |
|---|---|
| stria fornicis | A narrow, compact fibre bundle that extends along the line of attachment of the roof of the third ventricle to the thalamus on each side and terminates posteriorly in the habenular nucleus. It is composed of fibres originating in the septal area, the anterior perforated substance, the lateral preoptic nucleus, and the medial segment of the globus pallidus. Synonym: stria medullaris thalami, stria fornicis, stria ventriculi tertii. (05 Mar 2000) |
| stria longitudinalis lateralis | A thin longitudinal band of nerve fibres accompanied by gray matter, near each outer edge of the upper surface of the corpus callosum under cover of the cingulate gyru. Synonym: stria longitudinalis lateralis, stria tecta, tectal stria. (05 Mar 2000) |
| stria longitudinalis medialis | A thin longitudinal band of nerve fibres accompanied by gray matter, running along the surface of the corpus callosum on either side of the median line. Together with the lateral longitudinal stria it forms part of a thin layer of gray matter on the dorsal surface of the corpus callosum, the indusium griseum, a rudimentary component of the hippocampus. Synonym: stria longitudinalis medialis. (05 Mar 2000) |
| stria mallearis | A bright line seen through the membrana tympani, produced by the attachment of the manubrium of the malleus. Synonym: mallear stripe. (05 Mar 2000) |
| stria medullaris thalami | A narrow, compact fibre bundle that extends along the line of attachment of the roof of the third ventricle to the thalamus on each side and terminates posteriorly in the habenular nucleus. It is composed of fibres originating in the septal area, the anterior perforated substance, the lateral preoptic nucleus, and the medial segment of the globus pallidus. Synonym: stria medullaris thalami, stria fornicis, stria ventriculi tertii. (05 Mar 2000) |
| stria nasi transversa | A single deep horizontal groove at the level of the alae, with no associated defects. Synonym: transverse nasal groove. (05 Mar 2000) |
| stria spinosa | A faint groove occasionally caused by the chorda tympani nerve on the spine of the sphenoid. Synonym: Lucas' groove, sulcus spinosus. (05 Mar 2000) |
| stria tecta | A thin longitudinal band of nerve fibres accompanied by gray matter, near each outer edge of the upper surface of the corpus callosum under cover of the cingulate gyru. Synonym: stria longitudinalis lateralis, stria tecta, tectal stria. (05 Mar 2000) |
| stria terminalis | 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) |
| stria vascularis | A layer of highly vascular pigmented granular cells on the outer wall of the cochlear duct. (12 Dec 1998) |
| stria vascularis ductus cochlearis | The stratified epithelium lining the upper part of the ligamentum spirale cochleae; it is penetrated by capillaries and is believed to be the site of production of endolymph. Synonym: stria vascularis ductus cochlearis, psalterial cord, vascular stripe. (05 Mar 2000) |
| stria vascularis of cochlea | The stratified epithelium lining the upper part of the ligamentum spirale cochleae; it is penetrated by capillaries and is believed to be the site of production of endolymph. Synonym: stria vascularis ductus cochlearis, psalterial cord, vascular stripe. (05 Mar 2000) |
| stria ventriculi tertii | A narrow, compact fibre bundle that extends along the line of attachment of the roof of the third ventricle to the thalamus on each side and terminates posteriorly in the habenular nucleus. It is composed of fibres originating in the septal area, the anterior perforated substance, the lateral preoptic nucleus, and the medial segment of the globus pallidus. Synonym: stria medullaris thalami, stria fornicis, stria ventriculi tertii. (05 Mar 2000) |
| Nitabuch's stria | A layer of fibrin between the boundary zone of compact endometrium and the cytotrophoblastic shell in the placenta. Synonym: Nitabuch's layer, Nitabuch's stria. (05 Mar 2000) |
