| 영문 | facial nerve | 한글 | 얼굴신경 |
|---|---|---|---|
| 설명 | 표정근을 지배하는 큰 운동신경과 작은 중간신경으로 구성된다. 좁은 의미의 얼굴신경과 중간신경으로 이루어지는 혼합신경이다. 속귀신경과 함께 속귓길로 들어가고 그 바닥에서 속귀신경과 갈라져 얼굴신경관으로 들어가, 거의 직각으로 구부러지는 부분을 얼굴신경무릎이라 하며, 여기에 무릎신경마디가 있다. |

|---|---|---|---|
| 설명 | 안쪽장딴지피부신경 및 온장딴지신경의 교통지에서 시작하여 가쪽배쪽피부신경 및 가쪽발꿈치가지의 가지를 낸다. 넙다리 등쪽의 피부, 발꿈치와 발의 가쪽의 피부 및 관절에 분포하며, 일반 감각성 기능을 한다. |

| 영문 | spinal nerve | 한글 | 척수신경 |
|---|---|---|---|
| 설명 | 척수의 앞뿔에서 출발하는 운동신경과 뒷뿔으로 들어오는 감각신경이 합쳐서 형성되는 신경으로서 총 31쌍이 존재함. 목뼈신경이 8쌍, 자등뼈신경이 12쌍, 허리뼈의 신경이 5쌍, 엉치뼈의 6쌍을 이룸. |

| 영문 | auditory nerve | 한글 | 청신경 |
|---|---|---|---|
| 설명 | 귀에서 감지된 청각의 신호를 대뇌로 보내는 역할을 하는 신경. 달팽이신경라고 불리기도 한다. 그것은 소리를 전기적 신호로 바꾸어 신경으로 전달해 주는 달팽이의 집같이 생긴 기관을 달팽이라고 부르기 때문이다.  |

| trigeminal crest | That part of the cranial neural crest from which the ganglion of the fifth cranial nerve develops. (05 Mar 2000) |
|---|---|
| trigeminal decompression | Decompression of the trigeminal nerve root. (05 Mar 2000) |
| trigeminal ganglion | The semilunar-shaped ganglion containing the cells of origin of most of the sensory fibres of the trigeminal nerve. It is situated within the dural cleft on the cerebral surface of the petrous portion of the temporal bone and gives off the ophthalmic, maxillary, and part of the mandibular nerves. (12 Dec 1998) |
| trigeminal impression | A depression on the anterior surface of the petrous portion of the temporal bone, near the apex, lodging the trigeminal ganglion. Synonym: impressio trigeminalis. (05 Mar 2000) |
| trigeminal lemniscus | Collective term denoting the fibres ascending from the sensory nucleus of the trigeminus; one such fibre system originates from the main sensory nucleus, largely decussates, and ascends as the ventral trigeminal lemniscus to join the medial lemniscus with which it enters the ventral posterior nucleus of thalamus, terminating in the mediodorsal region of that nucleus; a second, uncrossed, fibre group follows an ascending course through central parts of the mesencephalic tegmentum ("dorsal trigeminal lemniscus"). The trigeminal lemniscus conveys tactile, pain, and temperature impulses from the skin of the face, the mucous membranes of the nasal and oral cavities, and the eye, as well as proprioceptive information from the facial and masticatory muscles. Synonym: lemniscus trigeminalis. (05 Mar 2000) |
| trigeminal neuralgia | <neurology> A disorder of trigeminal nerve (cranial nerve V) dysfunction. Synonym: tic douloureux. Characterised by excruciating paroxysms of pain in the lips, gums, cheek or chin, and, very rarely, in the distribution of the eye (ophthalmic division of the trigeminal nerve). (27 Sep 1997) |
| trigeminal nuclei | Nuclei of the trigeminal nerve situated in the brainstem. They include the nucleus of the spinal trigeminal tract (trigeminal nucleus, spinal), the principal sensory nucleus, the mesencephalic nucleus, and the motor nucleus. (12 Dec 1998) |
| trigeminal pulse | A pulse in which the beats occur in trios, a pause following every third beat. Synonym: pulsus trigeminus. (05 Mar 2000) |
| trigeminal rhizotomy | Division or section of a sensory root of the fifth cranial nerve, accomplished through a subtemporal (Frazier-Spiller operation), suboccipital (Dandy operation), or transtentorial approach. Synonym: retrogasserian neurectomy, retrogasserian neurotomy. (05 Mar 2000) |
| trigeminal rhythm | A cardiac arrhythmia in which the beats are grouped in trios, usually composed of a sinus beat followed by two extrasystoles. Synonym: trigeminy. (05 Mar 2000) |
| trigeminal system | <neurology> Neurons associated with the fifth or trigeminal nerve, the largest cranial nerve. The trigeminal system provides sensory innervation to the face and mucous membrane of the oral cavity, along with motor innervation to the muscles of mastication. It is called trigeminal because it has three major peripheral branches, the opthalmic, the maxillary and the mandibular nerves. (18 Nov 1997) |
| trigeminal tractotomy | Division of the descending fibres of the trigeminal tract in the medulla. Synonym: intramedullary tractotomy, Sjoqvist tractotomy. (05 Mar 2000) |
| motor nucleus of facial nerve | A group of motor neurons located in the ventrolateral region of the lower pontine tegmentum and innervating the facial muscles, the stapedius muscle in the middle ear, the posterior limb of the musculus digastricus, and the stylohyoid muscle. Synonym: nucleus nervi facialis, facial motor nucleus, motor nucleus of facial nerve, nucleus facialis. (05 Mar 2000) |
| nucleus of hypoglossal nerve | The motor nucleus innervating the intrinsic and four of the five extrinsic muscles of the tongue; it is located in the medulla oblongata near the midline, immediately beneath the floor of the inferior recess of the rhomboid fossa. Synonym: nucleus nervi hypoglossi, nucleus of hypoglossal nerve. (05 Mar 2000) |
| nucleus of oculomotor nerve | The composite group of motor neurons innervating all of the external eye muscles except the musculus rectus lateralis and musculus obliquus superior, and including the musculus levator palpebrae superioris; the most rostral component of the nucleus is the Edinger-Westphal nucleus which innervates the musculi sphincter pupillae and ciliaris via the ciliary ganglion. The oculomotor nucleus lies in the rostral half of the midbrain, near the midline in the most ventral part of the central gray substance; fibres of the medial longitudinal fasciculus form its lateral borders. Synonym: nucleus nervi oculomotorii, nucleus of oculomotor nerve. (05 Mar 2000) |
