| vena coronaria ventriculi | <anatomy, vein> Arises from a union of veins from both surfaces of the cardia of the stomach and an oesophageal tributary from the cardiac portion of the oesophagus; it runs in the lesser omentum and empties into the portal vein. See: oesophageal veins. Synonym: vena gastrica sinistra, coronary vein, vena coronaria ventriculi. (05 Mar 2000) |

| arteria coronaria dextra | <anatomy, artery> Origin, right aortic sinus; distribution, it passes around the right side of the heart in the coronary sulcus, giving branches to the right atrium and ventricle, including the atrioventricular branches and the posterior interventricular branch. Synonym: arteria coronaria dextra. (05 Mar 2000) |
| arteria coronaria sinistra | <anatomy, artery> Origin, left aortic sinus; distribution, it divides into two major branches, an anterior interventricular which descends in the anterior interventricular sulcus, and a circumflex branch which passes to the diaphragmatic surface of the left ventricle; gives atrial, ventricular, and atrioventricular branches. Synonym: arteria coronaria sinistra. (05 Mar 2000) |
| ramus nodi sinuatrialis arteriae coronaria dextra | artery to the sinuatrial (S-A) node |
| coronaria | A coronary artery, of the heart. (05 Mar 2000) |
| apertura lateralis ventriculi quarti | One of the two lateral openings of the fourth ventricle into the subarachnoid space at the cerebellopontine angle. Synonym: apertura lateralis ventriculi quarti, foramen lateralis ventriculi quarti, foramen of Key-Retzius, foramen of Luschka, Retzius' foramen. (05 Mar 2000) |
| apertura mediana ventriculi quarti | The large midline opening in the posterior inferior part of the roof of the fourth ventricle, connecting the ventricle with the cerebellomedullary cistern. Synonym: apertura mediana ventriculi quarti, arachnoid foramen, Magendie's foramen, median aperture of the fourth ventricle. (05 Mar 2000) |
| appendix ventriculi laryngis | A small diverticulum provided with mucous glands extending upward from the ventricle of the larynx between the vestibular fold and the lamina of the thyroid cartilage; it is a vestigial structure, being a much larger structure interdigitating with the neck musculature in some of the great apes where it serves as a resonating chamber. Synonym: sacculus laryngis, appendix ventriculi laryngis, Hilton's sac, laryngeal pouch. Origin: L. Sacculus (05 Mar 2000) |
| ramus choroidei ventriculi lateralis | Lateral ventrical branch of anterior choroid artery. See: choroid branches. (05 Mar 2000) |
| ramus choroidei ventriculi quarti | Fourth ventricle choroid branch of posterior inferior cerebellar artery. See: choroid branches. (05 Mar 2000) |
| ramus choroidei ventriculi tertii | Third ventricle choroid branch of anterior artery. See: choroid branches. (05 Mar 2000) |
| vena posterior ventriculi sinistri | Arises on the diaphragmatic surface of the heart near the apex, runs to the left and parallel to the posterior interventricular sulcus, and empties in the coronary sinus. Synonym: vena posterior ventriculi sinistri. (05 Mar 2000) |
| vena recessus lateralis ventriculi quarti | A small vein originating in the cerebellar tonsil, coursing by the lateral recess of the fourth ventricle on its way to terminate in the petrosal vein. Synonym: vein of lateral recess of fourth ventricle. (05 Mar 2000) |
| vena ventriculi lateralis lateralis | A vein draining deep portions of the temporal and parietal lobes; it runs in the lateral wall of the lateral ventricle to terminate in the superior thalamostriate vein. Synonym: vena ventriculi lateralis lateralis, lateral atrial vein, lateral vein of lateral ventricle. (05 Mar 2000) |
| vena ventriculi lateralis medialis | A vein that drains deep portions of the parietal and occipital lobes; it runs in the medial wall of the lateral ventricle to empty into the internal cerebral vein or the great cerebral vein. Synonym: vena ventriculi lateralis medialis, medial atrial vein, medial vein of lateral ventricle. (05 Mar 2000) |
