| 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) |
| diagonalis stria | See: Broca's diagonal band. (05 Mar 2000) |
| tectal stria | 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) |

| Langhans' stria | Fibrinoid that accumulates on the chorionic plate between the bases of placental villi during the first half of pregnancy. (05 Mar 2000) |
| lateral longitudinal stria | 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) |

(05 Mar 2000) |
| crossed pyramidal tract | Those fibres of the pyramidal tract that cross to the opposite side in the pyramidal decussation and descend in the dorsal half of the lateral funiculus of the spinal cord; they are distributed throughout the length of the spinal cord to interneurons of the zona intermedia of the spinal gray matter. See: pyramidal tract. Synonym: tractus corticospinalis lateralis, tractus pyramidalis lateralis, crossed pyramidal tract, fasciculus corticospinalis lateralis, fasciculus pyramidalis lateralis, lateral corticospinal tract, lateral pyramidal fasciculus.

| pyramidal | 1. Of or pertaining to a pyramid; in the form of a a pyramid; pyramidical; as, pyramidal cleavage. "The mystic obelisks stand up Triangular, pyramidal." (Mrs. Browning) 2. <chemistry> Same as Tetragonal. <mathematics> Pyramidal numbers, certain series of figurate numbers expressing the number of balls or points that may be arranged in the form of pyramids. Thus 1, 4, 10, 20, 35, etc, are trangular pyramidal numbers; and 1, 5, 14, 30, 55, etc, are square pyramidal numbers. Origin: Cf. F. Pyramidal. <anatomy> One of the carpal bones. See Cuneiform, 2 .
