| incisura ethmoidalis | An oblong gap between the orbital parts of the frontal bone in which the ethmoid bone is lodged. Synonym: incisura ethmoidalis. (05 Mar 2000) |
| labyrinthus ethmoidalis | A mass of air cells with thin bony walls forming part of the lateral wall of the nasal cavity; the cells are arranged in three groups, anterior, middle, and posterior, and are closed laterally by the orbital plate which forms part of the wall of the orbit. Synonym: labyrinthus ethmoidalis, ectethmoid, ectoethmoid, lateral mass of ethmoid bone. (05 Mar 2000) |
| lamina cribrosa ossis ethmoidalis | A horizontal lamina from which are suspended the labyrinth, on either side, and the lamina perpendicularis in the centre; it fits into the ethmoidal notch of the frontal bone and supports the olfactory lobes of the cerebrum, being pierced with numerous openings for the passage of the olfactory nerves. Synonym: lamina cribrosa ossis ethmoidalis, cribrum, sieve bone, sieve plate. (05 Mar 2000) |
| lamina orbitalis ossis ethmoidalis | A thin plate of ethmoid bone forming part of the medial wall of the orbit and the lateral wall for the ethmoidal labyrinth. Synonym: lamina orbitalis ossis ethmoidalis, lamina papyracea, orbital lamina of ethmoid bone, orbital layer of ethmoid bone, orbital plate, paper plate, papyraceous plate. (05 Mar 2000) |
| lamina perpendicularis ossis ethmoidalis | A thin plate of bone projecting downward from the crista galli of the ethmoid; it forms part of the nasal septum. Synonym: lamina perpendicularis ossis ethmoidalis. (05 Mar 2000) |
| fovea ethmoidalis | The roof of the ethmoid air cells. (05 Mar 2000) |
| vena auricularis posterior | <anatomy, vein> Drains the region posterior to the ear then merges with the retromandibular vein to form the external jugular vein. Synonym: vena auricularis posterior. (05 Mar 2000) |
| vena facialis posterior | <anatomy, vein> It is formed by the union of the superficial temporal and maxillary veins in front of the ear, runs posterior to the ramus of the mandible through the parotid gland, and unites with the posterior auricular vein to form the external jugular vein; it usually has a large communicating branch with the facial vein. Synonym: vena retromandibularis, posterior facial vein, temporomaxillary vein, vena facialis posterior. (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 septi pellucidi posterior | Vein draining the posterior part of the transparent septum; it empties into the superior thalamostriate vein. Synonym: vena septi pellucidi posterior. (05 Mar 2000) |
| valve of inferior vena cava | An endocardial fold extending from the anterior inferior margin of the inferior vena cava to the anterior part of the limbus fossa ovalis. Synonym: valvula venae cavae inferioris, caval valve, eustachian valve, sylvian valve. (05 Mar 2000) |
| vena | <anatomy> Any one of the great systemic veins connected directly with the heart. Vena contracta. The portal vein of the liver. A vein. Vena cava. Origin: L, literally, contracted vein, hollow vein. (11 Mar 1998) |
| vena advehens | Collective term for a series of branching channels in the early embryo receiving blood from the umbilical and/or vitelline venous systems and passing the mixed blood to the sinusoids of the liver; they become terminal branches of the hepatic portal vein. Synonym: vena afferentes hepatis. (05 Mar 2000) |
| vena afferentes hepatis | Collective term for a series of branching channels in the early embryo receiving blood from the umbilical and/or vitelline venous systems and passing the mixed blood to the sinusoids of the liver; they become terminal branches of the hepatic portal vein. Synonym: vena afferentes hepatis. (05 Mar 2000) |
