| terminal stria | 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) |
| terminal sulcus | 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) |
| terminal thread | A long, slender connective tissue (pia mater) strand extending from the extremity of the medullary cone to the internal aspect of the spinal dural sac (filum terminale internum); stout strands of connective tissue attaching the spinal dural sac to the coccyx (filum terminale externum), commonly called the coccygeal ligament.
