| ramus posterior nervi obturatorii | <anatomy, nerve> Branch supplying obturator externus muscle, then passing posterior to adductor brevis, supplying it and the adductor portion of the adductor magnus muscle. Synonym: ramus posterior nervi obturatorii. (05 Mar 2000) |
| ramus posterior rami dextri venae portae hepatis | <anatomy, vein> Posterior segmental branch of portal vein; branch to posterior segments of right lobe of liver. Synonym: ramus posterior rami dextri venae portae hepatis. (05 Mar 2000) |
| ramus posterior sulci lateralis cerebri | The long, posteriorly-directed continuation of the lateral cerebral sulcus which extends between the temporal lobe inferiorly and the parietal lobe superiorly, its termination surrounded by the supramarginal gyrus. Synonym: ramus posterior sulci lateralis cerebri. (05 Mar 2000) |
| ramus posterior venae pulmonalis dextrae superioris | <anatomy, vein> Drains posterior portion of superior lobe of right lung. Synonym: ramus posterior venae pulmonalis dextrae superioris. (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) |

| ventral posterior intermediate nucleus of thalamus | Intermediate part of the ventrobasal nuclear complex. See: ventral posterior nucleus of thalamus. Synonym: ventral posterior intermediate nucleus of thalamus. (05 Mar 2000) |
| ventral posterior nucleus of thalamus | The large posterior part of the ventral nucleus of the thalamus receiving the somatic sensory lemnisci (medial lemniscus, spinothalamic tract, trigeminal lemniscus) and the ascending gustatory (taste) lemniscus, and projecting in turn by way of the internal capsule to the cortex of the postcentral gyrus. The nucleus is somatotopically organised and subdivided into a ventral posterolateral nucleus of thalamus representing the leg, a ventral posterior intermediate nucleus of thalamus representing the arm, a ventral posteromedial nucleus of thalamus representing the face, and an arcuate nucleus of thalamus receiving the gustatory lemniscus. Synonym: nucleus ventralis posterior thalami, ventrobasal nucleus. (05 Mar 2000) |
