| nervus ulnaris | <anatomy, nerve> A major nerve of the upper extremity. In humans, the fibres of the ulnar nerve originate in the lower cervical and upper thoracic spinal cord (usually c7 to t1), travel via the medial cord of the brachial plexus, and supply sensory and motor innervation to parts of the hand and forearm.

| 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) |
| musculus | <anatomy> A muscle. For histologic description, see muscle. Synonym: muscle. Origin: L. A little mouse, a muscle, fr. Mus (mur-), a mouse (05 Mar 2000) |
| musculus abductor digiti minimi manus | Origin, pisiform bone and pisohamate ligament; insertion, medial side of base of proximal phalanx of the little finger; action, abducts and flexes little finger; nerve supply, ulnar. Synonym: musculus abductor digiti minimi manus, abductor muscle of little finger, musculus abductor digiti quinti. (05 Mar 2000) |
| musculus abductor digiti minimi pedis | Origin, lateral and medial processes of calcanean tuberosity; insertion, lateral side of proximal phalanx of fifth toe; action, abducts and flexes little toe; nerve supply, lateral plantar nerve. Synonym: musculus abductor digiti minimi pedis, abductor muscle of little toe, musculus abductor digiti quinti. (05 Mar 2000) |
| musculus abductor digiti quinti | Origin, pisiform bone and pisohamate ligament; insertion, medial side of base of proximal phalanx of the little finger; action, abducts and flexes little finger; nerve supply, ulnar. Synonym: musculus abductor digiti minimi manus, abductor muscle of little finger, musculus abductor digiti quinti. (05 Mar 2000) |
| musculus abductor hallucis | <anatomy, muscle> Origin, medial process of calcaneal tuberosity, flexor retinaculum, and plantar aponeurosis; insertion, medial side of proximal phalanx of great toe; action, abducts great toe; nerve supply, medial plantar. Synonym: musculus abductor hallucis, abductor muscle of great toe. (05 Mar 2000) |
| musculus abductor pollicis brevis | <anatomy, muscle> Origin, tubercle of trapezium and flexor retinaculum; insertion, lateral side of proximal phalanx of thumb; action, abducts thumb; nerve supply, median. Synonym: musculus abductor pollicis brevis, short abductor muscle of thumb. (05 Mar 2000) |
