| 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. |

| zygomatic | <anatomy> Of, pertaining to, or in the region of, the zygoma. Zygomatic arch, the arch of bone beneath the orbit, formed in most mammals by the union of the malar, or jugal, with the zygomatic process of the temporal bone. In the lower vertebrates other bones may help to form it, and there may be two arches on each side of the skull, as in some reptiles. Zygomatic process, a process of the temporal or squamosal bone helping to form the zygomatic arch. Origin: Cf. F. Zygomatique. Source: Websters Dictionary (01 Mar 1998) |
| zygomatic arch | The arch formed by the temporal process of the zygomatic bone that joins the zygomatic process of the temporal bone. Synonym: arcus zygomaticus, cheek bone, malar arch, zygoma. (05 Mar 2000) |
| zygomatic bone | A quadrilateral bone which forms the prominence of the cheek; it articulates with the frontal, sphenoid, temporal, and maxillary bone. Synonym: os zygomaticum, cheek bone, jugal bone, mala, malar bone, os malare, yoke bone, zygoma. (05 Mar 2000) |
| zygomatic border of greater wing of sphenoid bone | The border of the greater wing of the sphenoid that articulates with the zygomatic bone. Synonym: margo zygomaticus alae majoris, zygomatic margin of greater wing of sphenoid bone. (05 Mar 2000) |
| zygomatic diameter | The extreme breadth of the skull at the zygomatic arches. (05 Mar 2000) |
| zygomatic fossa | The cavity on the side of the skull bounded laterally by the zygomatic arch and ramus of the mandible, medially by the lateral pterygoid plate, anteriorly by the zygomatic process of the maxilla, posteriorly by the articular tubercle of the temporal bone and the posterior border of the lateral pterygoid plate, and above by the squama of the temporal bone and the infratemporal crest on the greater wing of the sphenoid bone. Synonym: fossa infratemporalis, zygomatic fossa. (05 Mar 2000) |
| zygomatic fractures | Fractures of the zygoma. (12 Dec 1998) |
| zygomatic margin of greater wing of sphenoid bone | The border of the greater wing of the sphenoid that articulates with the zygomatic bone. Synonym: margo zygomaticus alae majoris, zygomatic margin of greater wing of sphenoid bone. (05 Mar 2000) |
| zygomatic process of frontal bone | The massive projection of the frontal bone that joins the zygomatic bone to form the lateral margin of the orbit. Synonym: processus zygomaticus ossis frontalis. (05 Mar 2000) |
| zygomatic process of maxilla | The rough projection from the maxilla that articulates with the zygomatic bone. Synonym: malar process, processus zygomaticus maxillae. (05 Mar 2000) |
| zygomatic process of temporal bone | The anterior process of the temporal bone that articulates with the temporal process of the zygomatic bone to form the zygomatic arch. Synonym: processus zygomaticus ossis temporalis. (05 Mar 2000) |
