| 설명 | 중추신경계를 제외한 나머지 모든신경을 말함. 중추신경계는 뇌와 척수를 말하며, 그외 나머지 신경들로써 실제적으로 각 기관이나 사지 말단에 신경이 분포하며, 자극을 전달하는 일을 하는 신경을 모두 통틀어 말초신경이라 한다. 뇌에서 바로 나와 분포하는 뇌신경과 척수에서 기시하는 척수신경도 모두 말초신경에 해당한다. 또한 말초신경에는 각종 자율신경을 담당하는 교감신경, 부교감신경도 포함된다. |

|---|---|---|---|
| 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. |

| optic nerve | <anatomy, nerve> The optic nerve. The nerve carrying impulses for the sense of sight. Projection from the vertebrate retina to the midbrain. Embryologically, a CNS tract rather than a peripheral nerve. Popular experimental preparation for studies of regeneration of retino tectal projections in lower vertebrates and also for studies of glial cell lineage in CNS. Synonym: cranial nerve II. (18 Nov 1997) |

| optic nerve diseases | Diseases of the optic nerve. (12 Dec 1998) |
| optic nerve drusen | Basophilic, calcareous, laminated acellular bodies within the optic nerve anterior to the scleral lamina cribrosa. (05 Mar 2000) |
| optic nerve glioma | <radiology> F = M, child / young adult (75% less than 10 yrs, 90% less than 20 yrs), fusiform, isodense mass, with or without enhancement, rarely calcified associated with neurofibromatosis Cf: optic nerve meningioma (12 Dec 1998) |
| optic nerve head | The portion of the optic nerve seen in the fundus with the ophthalmoscope. It is formed by the meeting of all the retinal ganglion cell axons as they enter the optic nerve. Because the retina at the optic disk has no photoreceptors there is a corresponding blind spot in the visual field. (12 Dec 1998) |
| optic nerve hypoplasia | Congenitally small optic disk resulting from failure of development of retinal ganglion cells, with a reduced number of axons; visual impairment may be marked. See: de Morsier's syndrome. (05 Mar 2000) |
| optic nerve meningioma | <radiology> Female (80%), middle age, (24% occur before 10 yrs, but are associated with neurofibromatosis), tubular, hyperdense mass, intense tramtrack enhancement, ** Cf: optic nerve glioma (12 Dec 1998) |
| optic nerve sheath decompression | A venting of the optic nerve sheath into the retrobulbar space, by slitting or by fenestrating the sheath. See: optic nerve sheath fenestration. (05 Mar 2000) |
| optic nerve sheath fenestration | The cutting of a window in the dura of the optic nerve sheath to relieve papilledema and prevent further loss of optic nerve fibres. (05 Mar 2000) |
| external sheath of optic nerve | <anatomy, nerve> The outer sheath around the optic nerve, continuous with the dura mater. Synonym: vagina externa nervi optici, dural sheath of optic nerve. (05 Mar 2000) |
| vagal part of accessory nerve | <anatomy, nerve> The roots of the accessory nerve which arise from the medulla; the nerve fibres of the cranial root join the intracranial portion of the vagus nerve and are distributed to the pharyngeal plexus, providing the motor innervation of the soft palate (except the tensor veli palati) and the pharynx. Synonym: pars vagalis nervi accessorii, radices craniales, accessory portion of spinal accessory nerve, cranial roots, vagal part of accessory nerve, vagal part. (05 Mar 2000) |
| 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) |
| cochlear part of vestibulocochlear nerve | <anatomy, nerve> The cochlear part of the acoustic (8th cranial) nerve. The cochlear nerve fibres originate from neurons of the spiral ganglion and project peripherally to cochlear hair cells and centrally to the cochlear nuclei of the brainstem. They mediate the sense of hearing. (12 Dec 1998) |
| spinal part of accessory nerve | <anatomy, nerve> Originates from the upper five or six cervical spinal segments, emerges from the lateral surface of the spinal cord and ascends through the foramen magnum to join the cranial root. Synonym: radices spinales nervi accessorii, ramus externus nervi accessorii, pars spinalis nervi accessorii, spinal part of accessory nerve. (05 Mar 2000) |
| superior 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) |
