| 영문 | zygomatic bone | 한글 | 광대뼈 |
|---|---|---|---|
| 설명 | 얼굴볼부분의 돌출을 만드는 뼈이며 눈확의 아래 바깥쪽에 위치한다. 대략 마름모꼴이며 위턱뼈, 이마뼈 및 관자뼈의 광대뼈돌기에 끼어 있다. 관자돌기는 뒤쪽으로 돌출하여 관자뼈의 광대뼈돌기와 연결하며 광대뼈활을 만든다. 몸체는 4면이 있으며 아래쪽 내면은 위턱뼈의 광대뼈돌기와 봉합한다. 바깥쪽면에는 광대뼈얼굴구멍이 개구된다. 위쪽 내면은 눈확면이며 광대뼈눈확구멍이 개구된다. 후면은 옆머리면이며 광대뼈 옆머리구멍이 개구된다. 이들 3구멍은 몸체를 관통하는 광대뼈관에 의해 서로 연락되며 광대뼈신경이 지나간다. |

| 설명 | 구성－뼈(뼈조직). 이 조직은 굉장히 단단한 조직으로 뼈모세포에 의해서 생성된다. 뼈모세포가 생성한 이 조직은 뼈세포라는 세포를 동심원모양으로 쌓고 있다. 태아시기에는 모든 뼈가 연골조직으로 되어있다. 이런 연골조직이 발생하면서 점점 칼슘염의 침착에 의해서 뼈조직이 생긴다. 그리고 어린이의 경우에는 뼈끝판(epiphyseal plate)라는 곳이 있는데 이곳도 역시 연골조직으로 되어있어서 지속적으로 연골조직을 만들고 칼슘염의 침착이 생겨서 뼈의 성장이 된다. 양쪽에 넓어진 곳을 뼈끝(epiphysis)라고 하고 막대모양의 중간부분을 뼈몸통(diaphysis)라고 하고 이 양쪽의 이행부위를 뼈몸통끝(metaphysis)라고 한다. 뼈끝과 뼈몸통끝의 경계부위에 어린이에게선 뼈끝판(epiphyseal plate)라는 것이 존재하는데, 이곳은 연골조직으로 되어있으며 뼈의 길이성장에 중요한 역할을 하는 것이다. 어른이 되면 이곳의 연골조직은 모두 골조직으로 변화되어 줄모양의 흔적이 남는데, 이것을 뼈끝선이라고 한다. 긴뼈를 절단해 보면 겉으로는 매우 단단하고 조직이 치밀하고, 그 안쪽에는 겉에 비해서 무르고, 조직이 성긴 곳이 있는 걸 알 수가 있다. 겉의 단단한 곳을 치밀뼈(compact bone) 혹은 겉질뼈(cortical bone)이라고 한다. 여기에는 뼈조직이 동심원 모양을 이루고 치밀하게 배열되어 있고 그 동심원 내부에는 뼈세포가 위치하고 있다. 그리고 동심원의 중간에는 관이 있어서 이곳을 통해서 혈액과 영양분이 공급되는데 이관을 중심관(하버스관)이라고 한다. 그리고 내부에 위치한 성긴 곳을 갯솜뼈(Sponge Bone)이라고 한다. 역시 뼈조직으로 이루어진 곳이지만 그 배열이 치밀뼈에 비해서 성기고 외부의 힘에 대한 저항도 약한 조직이다. 이 조직의 내부에는 혈액의 세포를 생성하는 골수라는 것이 존재한다. 짧은 뼈(short bone)－손목이나 발목에서 볼 수 있는 짧고 모양이 불규칙한 뼈. 납작뼈(flat bone)－머리나 골반의 뼈와 같이 납작한 모양의 뼈. 종자뼈(sesamoid bone)－작고 구형인 뼈. 관절주위에 존재한다. 개개인에 따라서 존재하기도 하고 그렇지 않기도 한다. |

|---|---|---|---|
| 설명 | 생리적 연령의 일종으로 나이를 더함에 따른 뼈의 성숙도를 평가하여 어린이의 전신발육을 판정하는 것이다. 뼈나이 평가에는 손목뼈나 발목뼈의 X선사진을 바탕으로 각 화골중심의 형태나 수를 평가한다. 손목뼈의 화골개수를 세는 방법은 간단해서 그의 수는 난 해를 포함한 연령과 거의 일치하지만 뼈발육의 지속을 가늠할 수 있다. |

| 영문 | bone scan | 한글 | 뼈스캔 |
|---|---|---|---|
| 설명 | 뼈의 무기질은 칼슘과 인산염으로 이루어져 있다. 그래서 뼈에 병터가 있는 경우에는 뼈의 인산염분포나 양이 변화하게 된다. 이것을 이용하여 인산염에다가 방사선을 내보내는 물질을 붙여 환자에게 투여하고 그 물질이 내보내는 방사선을 이용하여 영상을 만들어서 뼈의 전반적인 상태나 병터의 발견에 이용하는 방법을 뼈스캔(bone scan)이라고 한다. |

|---|---|
| partial-thickness graft | A graft of portions of the skin, i.e., the epidermis and part of the dermis, or of part of the mucosa and submucosa, but not including the periosteum. Synonym: partial-thickness graft, split-skin graft. (05 Mar 2000) |
| pedicle graft | A skin flap sustained by a blood-carrying stem from the donor site during transfer, in periodontal surgery, a flap used to increase the width of attached gingiva, or to cover a root surface, by moving the attached gingiva, which remains joined at one side, to an adjacent position and suturing the free end. (05 Mar 2000) |
| Reverdin graft | Small bits of skin, of partial or full thickness, removed from a healthy area and seeded in a site to be covered. Synonym: Reverdin graft. (05 Mar 2000) |
| 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. To cover, as a ring bolt, block strap, splicing, etc, with a weaving of small cord or rope-yarns. Origin: F. Greffer. See Graft. Source: Websters Dictionary (01 Mar 1998) |
| 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) |
| graft survival | <haematology> The survival of a graft in a host, the factors responsible for the survival and the changes occurring within the graft during growth in the host. (12 Dec 1998) |
| graft-versus-host disease | <haematology> A common and serious, complication of bone marrow transplantation where there is a reaction of donated bone marrow against a patient's own tissue. When donor lymphocytes or a graft containing lymphocytes that are immunologically competent are given to a patient that has low immunological competence, an incompatibility reaction can result. This is due to antibodies from the donor against antigens in the host. This is due to mismatch of MHC Class I antigens and can produce lymphocyte clones that will react by a variety of processes against the host and cause damage. The clinical condition can be fatal and is due to the donor's immune cells recognising the host cells as foreign. The clinical entity characterised by anorexia, diarrhoea, loss of hair, leukopenia, thrombocytopenia, growth retardation, and eventual death brought about by the graft-versus-host reaction. It can occur in either chronic or acute forms and is treatable by immunosuppressive drugs. Seen most commonly following bone marrow transplantation, acute disease is seen after 5-40 days and chronic disease weeks to months after transplantation, affecting, principally, the gastrointestinal tract, liver, and skin. Radiological appearances of the gastrointestinal tract include; thickened wall, mucosal folds thickened or effaced, increased secretions most likely to be rapid transit of GI tract, mass most likely to be focal oedema, fibrosis, hallmark: diffuse, uniform thickening of small bowel. Synonym: GVH disease. Acronym: GVHD (20 Sep 2002) |
