| 영문 | optic nerve | 한글 | 시각신경 |
|---|---|---|---|
| 설명 | 시각을 인지하는 신경. 이 신경은 단지 감각신경으로서만 작용한다. 따라서 어떤 사물을 따라 눈을 움직일 수 있는 것은 이 시각신경과는 무관하다(이것은 눈돌림신경(oculomotor nerve)에 의해 가능하다). 또한 시각신경은 고위중추신경계인 뇌에서 직접 분지하므로 손상시 재생은 불가능하며, 이에 대한 치료법은 없다. |

|---|---|---|---|
| 설명 | 여러 기관들의 서로간 상호연결체계가 바로 신경계이다. 이러한 신경계는 각 신경세포들에 의해 이루어지고 있으며, 여기에는 중추신경계(central nerve system: CNS)와 말초신경계(peripheral nerve system: PNS)가 있다. 중추신경계란 뇌와 척수를 말하며, 말초신경계는 12쌍의 뇌신경(cranial nerve: 뇌에서 기시하여 주로 얼굴부위와 목 부위에 분포한다)과 31쌍의 척수신경(spinal nerve: spinal cord에서 각기 양쪽으로 쌍을 이루어 나오는데 주로 목이하부위의 신체 각 부분으로 분포하게 된다)으로 구성되어 있다. 또한 말초신경계에는 앞에서 말한 뇌신경과 척수신경외에 자율신경계가 존재한다. 자율신경계는 다시 교감신경과 부교감신경으로 나뉘어져 서로간의 올바른 상호작용으로 몸속에서 여러 가지 작용을 수행한다. |

|---|---|---|---|
| 설명 | 신경세포는 올바른 신경전달을 위한 각 부분별로 나뉘어져 있다. 신경세포에서는 전해져오는 자극을 전기적인 신호로 바뀌어 보내거나 받게 된다. 이런 전기적인 현상은 각 신경세포내에 존재하는 각 이온채널(ion channel: ion이란 나트륨, 칼륨 등을 지칭하는 말들로써, 이들이 세포막에 의해 나뉘어질 때 생기는 전압차가 전기적 자극을 일으키고 유지하는데 결정적인 역할을 한다)들의 작용에 의해 이루어지게 된다. |

| acoustic nerve | <anatomy, nerve> The 8th cranial nerve. The acoustic (or vestibulocochlear) nerve has a cochlear part which is concerned with hearing and a vestibular part which mediates the sense of balance and head position. The fibres of the cochlear nerve originate from neurons of the spiral ganglion and project to the cochlear nuclei. The fibres of the vestibular nerve arise from neurons of scarpa's ganglion and project to the vestibular nuclei. (12 Dec 1998) |
|---|---|
| acoustic nerve diseases | Diseases of the eighth cranial nerve. These include vestibular neuronitis, cochlear neuritis and acoustic neuroma. (12 Dec 1998) |
| afferent nerve | <anatomy, physiology> A nerve which transmits impulses from the tissues to the brain and spinal cord (for example sensory nerve). (27 Sep 1997) |
| Andersch's nerve | <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) |
| anterior ampullar nerve | <anatomy, nerve> A branch of the utriculoampullar nerve that supplies the crista ampullaris of the anterior saemicircular duct. Synonym: nervus ampullaris anterior. (05 Mar 2000) |
| anterior antebrachial nerve | <anatomy, nerve> A branch of the median arising in elbow region, running on interosseous membrane, supplying the flexor pollicis longus, part of flexor digitorum profundus and the pronator quadratus muscles, as well as radiocarpal and intercarpal joints. Synonym: nervus interosseus anterior, ramus profundus nervi radialis, nervus antebrachii anterior, anterior antebrachial nerve, volar interosseous nerve. (05 Mar 2000) |
| anterior crural nerve | <anatomy, nerve> A nerve originating in the lumbar spinal cord (usually l2 to l4) and traveling through the lumbar plexus to provide motor innervation to extensors of the thigh and sensory innervation to parts of the thigh, lower leg, and foot, and to the hip and knee joints. (12 Dec 1998) |
| anterior cutaneous branch of iliohypogastric nerve | <anatomy, nerve> Distribution, skin on pubis. Synonym: ramus cutaneus anterior nervi iliohypogastrici, genital branch of iliohypogastric nerve. (05 Mar 2000) |
| anterior ethmoidal nerve | <anatomy, nerve> A branch of the nasociliary nerve; passes through anterior ethmoidal foramen on superomedial wall of orbit into cranial cavity, giving rise to anterior meningeal nerves, then passes through cribriform plates into nasal cavity, supplying anterosuperior nasal mucosa. Synonym: nervus ethmoidalis anterior. (05 Mar 2000) |
| anterior interosseous nerve | <anatomy, nerve> A branch of the median arising in elbow region, running on interosseous membrane, supplying the flexor pollicis longus, part of flexor digitorum profundus and the pronator quadratus muscles, as well as radiocarpal and intercarpal joints. Synonym: nervus interosseus anterior, ramus profundus nervi radialis, nervus antebrachii anterior, anterior antebrachial nerve, volar interosseous nerve. (05 Mar 2000) |
| anterior superior alveolar branches of infraorbital nerve | <anatomy, nerve> The branches of the superior alveolar nerve that supply the incisors, canines, premolars, and first molar by their contributions to the superior dental plexus.

| anterior supraclavicular nerve | <anatomy, nerve> One of several nerves arising from the cervical plexus which supply the skin over the upper medial part of the thorax. Synonym: nervus supraclavicularis medialis, anterior supraclavicular nerve. (05 Mar 2000) |
| anterior tibial nerve | <anatomy, nerve> One of the terminal branches of the common peroneal nerve, arising at the fibular neck and passing into the anterior compartment of the leg; it supplies the tibialis anterior, extensor hallucis longus, extensor digitorum longus, and peroneus tertius muscles in the leg, then crosses the ankle joint to supply the muscles on the dorsum of the foot (extensors hallucis and digitorum brevis) becoming cutaneous to innervate adjacent sides of the great and second toes. Synonym: nervus fibularis profundus, nervus peroneus profundus, anterior tibial nerve, deep fibular nerve. (05 Mar 2000) |
| aortic nerve | <anatomy, nerve> A branch of the vagus which ends in the aortic arch and base of the heart; composed entirely of afferent fibres; its stimulation elicits a brainstem reflex which causes slowing of the heart, dilation of the peripheral vessels, and a fall in blood pressure.
