| nervus tensoris tympani | <anatomy> A branch of the mandibular nerve conveying fibres from the motor root of the trigeminal nerve which pass through the otic ganglion without synapse to supply the tensor tympani muscle. Synonym: nervus tensoris tympani. (05 Mar 2000) |
|---|---|
| nervus tensoris veli palatini | <anatomy> A branch of the mandibular nerveconveying fibres from the motor root of the trigeminal nerve which pass through the otic ganglion without synapse to supply the tensor veli palatini muscle. Synonym: nervus tensoris veli palatini. (05 Mar 2000) |
| nervus tentorii | <anatomy, nerve> The tentorial branch, a branch arising in a recurrent fashion from the intracranial portion of the ophthalmic nerve supplying the tentorium and supratentorial falx cerebri. Synonym: ramus tentorii, nervus tentorii. (05 Mar 2000) |
| nervus thoracicus longus | <anatomy, nerve> Arises from the fifth, sixth, and seventh cervical nerves (roots of brachial plexus), descends the neck behind the brachial plexus, and is distributed to the serratus anterior muscle; it is somewhat unusual in that it courses on the superficial aspect of the muscle is supplies; its paralysis results in "winged scapula". Synonym: nervus thoracicus longus, Bell's respiratory nerve, external respiratory nerve of Bell, posterior thoracic nerve. (05 Mar 2000) |
| nervus thoracodorsalis | <anatomy, nerve> Arises from the posterior cord of the brachial plexus; it contains fibres from the sixth, seventh, and eighth cervical nerves and supplies the latissimus dorsi muscle. Synonym: nervus thoracodorsalis, long subscapular nerve. (05 Mar 2000) |
| nervus tibialis | <anatomy, nerve> The medial terminal branch of the sciatic nerve. The tibial nerve fibres originate in lumbar and sacral spinal segments (l4 to s2). They supply motor and sensory innervation to parts of the calf and foot. (12 Dec 1998) |
| nervus transversus colli | <anatomy, nerve> A branch of the cervical plexus that supplies the skin over the anterior triangle of the neck. Synonym: nervus transversus colli, cutaneous cervical nerve, nervus cervicalis superficialis, superficial cervical nerve, transverse nerve of neck. (05 Mar 2000) |
| nervus trigeminus | <anatomy, nerve> The trigeminal nerve is responsible for sensory enervation of the face and motor enervation to muscles of mastication (chewing). There are three divisions of the fifth cranial nerve, ophthalmic, maxillary and mandibular. Lesions of the sensory root to the trigeminal nerve can result in pain or loss of sensation in the face. Lesion of the motor root result in deviation of the jaw toward the paralysed side and difficulty chewing. Synonym: cranial nerve V. (27 Sep 1997) |
| nervus trochlearis | <anatomy, nerve> The trochlear nerve controls an extraocular muscle. Lesions of this nerve will result in rotation of the eyeball upward and outward (and double vision). Synonym: cranial nerve IV. (27 Sep 1997) |
| nervus tympanicus | <anatomy, nerve> A nerve from the inferior ganglion of the glossopharyngeal nerve, passing through the tympanic canaliculus to the tympanic cavity, forming there the tympanic plexus which supplies the mucous membrane of the tympanic cavity, mastoid cells, and auditory tube; presynaptic parasympathetic fibres also pass through the tympanic nerve via the lesser superficial petrosal nerve to the otic ganglion, where they synapse with postsynaptic fibres that continue to supply the parotid gland. Synonym: nervus tympanicus, Andersch's nerve, Jacobson's nerve. (05 Mar 2000) |
| 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. (12 Dec 1998) |
| 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) |
