1. A stripe, band, streak, or line, distinguished by color, texture, depression, or elevation from the tissue in which it is found.striation (1) ; 2. striae cutis distensae [L. channel, furrow]

brown striaeRetzius' striae
stri´ae cilia´resshallow radial grooves on the surface of the orbiculus ciliaris extending from the teeth of the ora serrata and leading into the valleys between the ciliary processes.
stri´ae cu´tis disten´saebands of thin wrinkled skin, initially red but becoming purple and white, which occur commonly on the abdomen, buttocks, and thighs at puberty and/or during and following pregnancy, and result from atrophy of the dermis and overextension of the skin; also associated with ascites and Cushing's syndrome.atrophoderma striatum, lineae albicantes, lineae atrophicae, linear atrophy, stretch marks, stria (2) , striae atrophicae, striate atrophy of skin, traction atrophy, vergeture;

stri´ae lanci´sithe lateral longitudinal s. and the medial longitudinal s.
Langhans' s.fibrinoid that accumulates on the chorionic plate between the bases of placental villi during the first half of pregnancy.
lateral longitudinal s.a thin longitudinal band of nerve fibers accompanied by gray matter, near each outer edge of the upper surface of the corpus callosum under cover of the cingulate gyru.s. longitudinalis lateralis [NA] , s. tecta, tectal s;
s. longitudina´lis latera´lis [NA] lateral longitudinal s
s. longitudina´lis media´lis [NA] medial longitudinal s
s. mallea´ris [NA] a bright line seen through the membrana tympani, produced by the attachment of the manubrium of the malleus.mallear stripe;
medial longitudinal s.a thin longitudinal band of nerve fibers accompanied by gray matter, running along the surface of the corpus callosum on either side of the median line. Together with the lateral longitudinal s. 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.s. longitudinalis medialis [NA] ;
stri´ae medulla´res ventric´uli quar´ti [NA] medullary striae of fourth ventricle
s. medulla´ris thal´ami [NA] medullary s. of thalamus
medullary striae of fourth ventricleslender fascicles of fibers extending transversally below the ependymal floor of the ventricle from the median sulcus to enter the inferior cerebellar peduncle. They arise from the arcuate nuclei on the ventral surface of the medullary pyramid.striae medullares ventriculi quarti [NA] , acoustic striae, auditory striae, Bergmann's cords, medullary teniae, teniae acusticae;
medullary s. of thalamusa narrow, compact fiber 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 fibers originating in the septal area, the anterior perforated substance, the lateral preoptic nucleus, and the medial segment of the globus pallidus.s. medullaris thalami [NA] , s. fornicis, s. ventriculi tertii;
s. na´si transver´saa single deep horizontal groove at the level of the alae, with no associated defects.transverse nasal groove;
Nitabuch's s.Nitabuch's membrane
stri´ae olfacto´riae [NA] olfactory striae
olfactory striaethree distinct fiber bands (s. medialis, s. intermedia, s. lateralis) that caudally extend the olfactory tract beyond its attachment to the olfactory trigone. The medial s. curves dorsally into the tenia tecta; the intermediate, often barely visible, extends straight back and terminates in the olfactory tubercle; the lateral olfactory s., the largest of the three, passes along the lateral side of the olfactory tubercle, curving laterally as far as the limen insulae, then sharply medially to reach the uncus of the parahippocampal gyrus where it terminates in the plexiform layer of the olfactory cortex. See also medial longitudinal s.striae olfactoriae [NA] , olfactory roots;
stri´ae paral´lelaeRetzius' striae
striae ret´inaeconcentric lines on the surface of an abnormal retina.
striae retinaePaton's lines, under line
Retzius' striaedark concentric lines crossing the enamel prisms of the teeth, seen in axial cross sections of the enamel.brown striae, striae parallelae;
Rohr's s.layer of fibrinoid in the intervillous spaces of the placenta.
s. spino´saa faint groove occasionally caused by the chorda tympani nerve on the spine of the sphenoid.Lucas' groove, sulcus spinosus;
s. tec´talateral longitudinal s
tectal s.lateral longitudinal s
terminal s.a slender, compact fiber 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 fibers 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.s. terminalis [NA] , Foville's fasciculus, Tarin's tenia, tenia semicircularis;
s. termina´lis [NA] terminal s
s. vascularis of cochleathe 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.s. vascularis ductus cochlearis [NA] , psalterial cord, vascular stripe;
s. vascula´ris duc´tus cochlea´ris [NA] s. vascularis of cochlea
s. ventric´uli ter´tiimedullary s. of thalamus
Wickham's striaefine whitish lines, having a network arrangement, on the surface of lichen planus papules.
