| 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) |
| sulcus terminalis | Sulcus terminalis linguae; a V-shaped groove, with apex pointing backward, on the surface of the tongue, marking the separation between the oral, or horizontal, and the pharyngeal, or vertical, parts, sulcus terminalis atrii dextri; a groove on the surface of the right atrium of the heart, marking the junction of the primitive sinus venosus with the atrium. Synonym: terminal sulcus. (05 Mar 2000) |
| incisura terminalis auris | A deep notch separating the lamina tragi and cartilage of the external auditory meatus from the main auricular cartilage, the two being connected below by the isthmus. Synonym: incisura terminalis auris, auricular notch. (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) |
| lamina terminalis cerebri | A thin plate passing upward from the optic chiasm and forming the rostral boundary of the third ventricle; membrane closing the rostral neuropore. Synonym: lamina terminalis cerebri, lamina cinerea, terminal plate, velum terminale. (05 Mar 2000) |
| lamina terminalis of cerebrum | A thin plate passing upward from the optic chiasm and forming the rostral boundary of the third ventricle; membrane closing the rostral neuropore. Synonym: lamina terminalis cerebri, lamina cinerea, terminal plate, velum terminale. (05 Mar 2000) |
| fossa terminalis urethrae | The terminal dilated portion of the urethra in the glans penis. Synonym: fossa navicularis urethrae, fossa terminalis urethrae, Morgagni's fossa, Morgagni's fovea. (05 Mar 2000) |
| linea terminalis | An oblique ridge on the inner surface of the ilium and continued on the pubis, which forms the lower boundary of the iliac fossa; it separates the true from the false pelvis. Synonym: iliopectineal line, terminal line. (05 Mar 2000) |
| wing of crista galli | A small lateral expansion of the ethmoid bone from the front of the crista galli on each side that articulates with the frontal bone and forms the foramen caecum. Synonym: ala cristae galli, alar process. (05 Mar 2000) |
| crista | Synonym: crest. Origin: L. Crest (05 Mar 2000) |
| crista ampullaris | An elevation on the inner surface of the ampulla of each saemicircular duct; filaments of the vestibular nerve pass through the crista to reach hair cells on its surface; the hair cells are capped by the cupula, a gelatinous protein-polysaccharide mass. Synonym: crista ampullaris, acoustic crest, transverse septum. (05 Mar 2000) |
| crista arcuata cartilaginis arytenoideae | The ridge on the anterior surface of the arytenoid cartilage that separates the triangular from the oblong fovea. Synonym: crista arcuata cartilaginis arytenoideae, arched crest, arcuate crest. (05 Mar 2000) |
| crista basilaris ductus cochlearis | An inward projection of the spiral ligament of the cochlea to which is attached the basilar membrane forming the floor of the cochlear duct. Synonym: crista basilaris ductus cochlearis. (05 Mar 2000) |
| crista buccinatoria | A ridge passing from the base of the coronoid process of the mandible to the region of the last molar tooth; it gives attachment to the mandibular part of the buccinator muscle. Synonym: crista buccinatoria. (05 Mar 2000) |
