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

| 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. |

| 영문 | nerve | 한글 | 신경 |
|---|---|---|---|
| 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. |

| graft | To insert scions from one tree, or kind of tree, etc, into another; to practice grafting. A small shoot or scion of a tree inserted in another tree, the stock of which is to support and nourish it. The two unite and become one tree, but the graft determines the kind of fruit. A branch or portion of a tree growing from such a shoot. <surgery> A portion of living tissue used in the operation of autoplasty. Origin: OE. Graff, F. Greffe, originally the same word as OF. Grafe pencil, L. Graphium, Gr, fr. To write; prob. Akin to E. Carve. So named from the resemblance of a scion or shoot to a pointed pencil. Cf. Graphic, Grammar. 1. To insert (a graft) in a branch or stem of another tree; to propagate by insertion in another stock; also, to insert a graft upon. [Formerly written graff. 2. <surgery> To implant a portion of (living flesh or akin) in a lesion so as to form an organic union. 3. To join (one thing) to another as if by grafting, so as to bring about a close union. "And graft my love immortal on thy fame !" (Pope) 4.

| graft enhancement, immunologic | The induction of prolonged survival and growth of allografts of either tumours or normal tissues which would ordinarily be rejected. It may be induced passively by introducing graft-specific antibodies from previously immunised donors, which bind to the graft's surface antigens, masking them from recognition by T-cells; or actively by prior immunization of the recipient with graft antigens which evoke specific antibodies and form antigen-antibody complexes which bind to the antigen receptor sites of the T-cells and block their cytotoxic activity. (12 Dec 1998) |
| graft occlusion | <physiology> Obstruction of flow in biological or prosthetic vascular grafts. (12 Dec 1998) |
| graft rejection | <haematology, immunology> When donated bone marrow infused during a bone marrow transplant is rejected by the patients body or does not take. (16 Dec 1997) |
