| caroticotympanic nerve | <anatomy, nerve> One of two sympathetic branches from the internal carotid plexus to the tympanic plexus. Synonym: nervus caroticotympanicus, small deep petrosal nerve. (05 Mar 2000) |
|---|---|
| vertebral nerve | <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) |
| carotid sinus nerve | <anatomy, nerve> A branch of the glossopharyngeal nerve that innervates the baroreceptors in the wall of the carotid sinus and the chemoreceptors in the carotid body. Synonym: ramus sinus carotici, carotid sinus branch, Hering's sinus nerve, intercarotid nerve, nerve to carotid sinus, sinus nerve of Hering. (05 Mar 2000) |
| masseteric nerve | <anatomy, nerve> A muscular branch of the mandibular nerve passing through the mandibular notch to the medial surface of the masseter muscle which it supplies and the temporomandibular joint. Synonym: nervus massetericus. (05 Mar 2000) |
| recurrent laryngeal nerve | <anatomy, nerve> A branch of a nerve (the vagus nerve) that comes down the neck and turns back ( recurs ) to supply the larynx (the voice box ). (12 Dec 1998) |
| recurrent meningeal nerve | <anatomy, nerve> Meningeal branches of 1) mandibular, 2) maxillary, 3) ophthalmic, and 4) spinal nerves. (05 Mar 2000) |
| recurrent nerve | <anatomy, nerve> A branch of a nerve (the vagus nerve) that comes down the neck and turns back ( recurs ) to supply the larynx (the voice box ). (12 Dec 1998) |
| masticator nerve | <anatomy, nerve> The smaller root of the trigeminal nerve, composed of fibres originating from the trigeminal motor nucleus and emerging from the pons medial to the much larger sensory root, to join the mandibular nerve; it carries motor and proprioceptive fibres to the muscles derived from the first bronchial (mandibular) arch, including the four muscles of mastication, plus the mylohyoid, anterior belly of the digastric, and the tensores tympani and veli palati. Synonym: radix motoria nervi trigemini, masticator nerve, portio minor nervi trigemini. (05 Mar 2000) |
| vestibular nerve | <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) |
| vestibular part of vestibulocochlear nerve | <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) |
| vestibular root of vestibulocochlear nerve | Radix vestibularis, radix superior nervi vestibulocochlearis, superior root of vestibulocochlear nerve, vestibular root of vestibulocochlear nerve. (05 Mar 2000) |
| vestibulocochlear nerve | <anatomy, nerve> The vestibulocochlear nerve is responsible for the sense of hearing and balance (body position sense). Lesions of the eighth nerve can result in deafness, tinnitus, dizziness, vertigo and vomiting. Synonym: cranial nerve VIII. (27 Sep 1997) |
| maxillary nerve | <anatomy, nerve> The intermediate sensory division of the trigeminal (5th cranial) nerve. The maxillary nerve carries general afferents from the intermediate region of the face including the lower eyelid, nose and upper lip, the maxillary teeth, and parts of the dura. (12 Dec 1998) |
| vidian nerve | The nerve constituting the parasympathetic and sympathetic root of the pterygopalatine ganglion; it is formed in the region of the foramen lacerum by the union of the greater superficial petrosal and the deep petrosal nerves, and runs through the pterygoid canal to the pterygopalatine fossa. Synonym: nervus canalis pterygoidei, radix facialis, facial root, vidian nerve. (05 Mar 2000) |
| glaucomatous nerve-fibre bundle scotoma | See: caecocentral scotoma. (05 Mar 2000) |
