| nervus utricularis | <anatomy, nerve> A branch of the utriculoampullar nerve, supplying the macula of the utricle. Synonym: nervus utricularis. (05 Mar 2000) |
|---|---|
| nervus utriculoampullaris | <anatomy, nerve> A division of the vestibular part of the eighth cranial nerve; it gives off branches to the macula of the utricle (utricular nerve) and to the cristae of the ampullae of the anterior and lateral saemicircular ducts (anterior and lateral ampullary nerves). Synonym: nervus utriculoampullaris. (05 Mar 2000) |
| nervus vagus | <anatomy, nerve> The vagus nerve enervates the gut (gastrointestinal tract), heart and larynx. Lesions of the tenth nerve usually result in a horse voice, but may also cause difficulty in swallowing or talking. Synonym: cranial nerve X. (27 Sep 1997) |
| nervus vascularis | <anatomy, nerve> A small nerve filament that supplies the wall of a blood vessel. Synonym: nervus vascularis. (05 Mar 2000) |
| nervus vertebralis | <anatomy, nerve> A branch from the stellate ganglion that ascends along the vertebral artery to the level of the axis or atlas, giving branches to the cervical nerves and meninges. Synonym: nervus vertebralis. (05 Mar 2000) |
| nervus vestibularis | <anatomy, nerve> The vestibular part of the acoustic (8th cranial) nerve. The vestibular nerve fibres arise from neurons of scarpa's ganglion and project peripherally to vestibular hair cells and centrally to the vestibular nuclei of the brainstem. These fibres mediate the sense of balance and head position. (12 Dec 1998) |
| nervus vestibulocochlearis | vestibulocochlear nerve. See entries under radix |
| nervus zygomaticus | <anatomy, nerve> A branch of the maxillary nerve in the inferior orbital fissure through which it passes; it gives rise to two sensory branches, the zygomaticotemporal and zygomaticofacial, which supply the skin of the temporal and zygomatic regions and is continued as the communicating branch of the lacrimal nerve with the zygomatic nerve. Synonym: nervus zygomaticus, orbital nerve, temporomandibular nerve. (05 Mar 2000) |
| apex of the posterior horn | The pointed extremity of each posterior gray column or cornu of the spinal cord. Synonym: apex cornus posterioris, caput cornus, tip of posterior horn. (05 Mar 2000) |
| arcus posterior atlantis | The posterior arch of the atlas that connects the lateral masses of the atlas posteriorly, forming the posterior wall of the vertebral canal at this level. Synonym: arcus posterior atlantis. (05 Mar 2000) |
| area intercondylaris posterior tibiae | The deep notch between the tibial condyles posteriorly to which attaches the posterior cruciate ligament. Synonym: area intercondylaris posterior tibiae. (05 Mar 2000) |
| arteria alveolaris superior posterior | <anatomy, artery> Origin, 3rd part of maxillary artery within pterygopalatine fossa; distribution, molar and premolar teeth, gingiva and mucous membrane of maxillary sinus. Synonym: arteria alveolaris superior posterior, posterior alveolar artery, posterior dental artery. (05 Mar 2000) |
| arteria caecalis posterior | <anatomy, artery> Origin, ileocolic artery; distribution, posterior region of caecum. Synonym: arteria caecalis posterior. (05 Mar 2000) |
| arteria cerebelli inferior posterior | <anatomy, artery> Origin, vertebral; distribution, lateral medulla, choroid plexus of fourth ventricle, and cerebellum; anastomoses, superior cerebellar and anterior inferior cerebellar. Synonym: arteria cerebelli inferior posterior. (05 Mar 2000) |
| arteria cerebri posterior | <anatomy, artery> Formed by the bifurcation of the basilar artery; it passes around the cerebral peduncle to reach the medial aspect of the hemisphere; for descriptive purposes it is divided into three parts: 1) the precommunical part (P1 segment of clinical terminology), the part before the junction with the posterior communicating artery, supplying parts of the thalamus, hypothalamus, and midbrain; 2) the postcommunical part (P2), supplying the thalamus, cerebral peduncles, and the choroid plexuses of the lateral and third ventricles; and 3) the terminal or cortical part, supplying the cortex of the temporal (P3) and occipital (P4) lobes. Synonym: arteria cerebri posterior. (05 Mar 2000) |
