| 영문 | myometrium | 한글 | 자궁근육층, 자궁근층 |
|---|---|---|---|
| 설명 | 자궁의 구조물을 부르는데 쓰이는 말. 자궁은 안쪽의 내막(endometrium) 이 있어 여기의 조직이 떨어져 나오는 것이 월경에 해당된다. 또한 자궁의 수축 등을 일으키는 자궁근육층이 존재하고, 자궁을 감싸고 있는 자궁외막층(perimetrium)이 존재한다. |

| 영문 | myopia | 한글 | 근시 |
|---|---|---|---|
| 설명 | 시각을 형성하는 눈의 촛점이 망막보다 앞쪽에 맞추어져 가까이 있는 물체는 보이지만, 멀리 있는 물체가 잘 보이지 않는 현상. 정도에 따라 심한 경우 고도근시(high myopia)라 부르며, 이 경우에 여러 가지 합병증의 발생가능성이 높으며, 선천적인 경우가 많다. |

| 영문 | myosin | 한글 | 굵은근육미세섬유, 미오신 |
|---|---|---|---|
| 설명 | 골격근 근육섬유 속의 근육원섬유는 굵은 잔섬유와 가는 잔섬유로 이루어지는데, 미오신은 굵은 잔섬유를 구성하는 근단백질의 40% 이상을 차지하는 글로불린 모양의 단백질이다. 거의 불용성에 가까운 젤을 형성하기 때문에 근육의 수축과 이완에 중요한 역할을 한다. 1942년에 센트죄르지가 발견하였다. 굵은 잔섬유는 직경 1~12nm, 길이 1.6μm로, 미오신분자가 중합되어 만들어졌으며, 두 개의 팽창된 머리부분을 갖고 있다. 근절(sarcomere: 근원섬유 중의 섬유 방향의 반복단위)의 굵은 잔섬유는 200~400개의 미오신 분자로 이루어져 있다. 분자량 50만, 길이 160nm, 지름 2nm의 성냥개비 모양의 구조이다. 분자량 21만 5000인 폴리펩티드 두개와 몇 개의 저분자량 단백질로 되어 있는데, 이것들이 올바르게 짝지어져야 비로소 생물활성이 나타나게 된다. |

| myoblastoma | <oncology, tumour> A benign tumour originating from muscle cells. (09 Oct 1997) |
|---|---|
| myobradia | Sluggish reaction of muscle following stimulation. Origin: myo-+ G. Bradys, slow (05 Mar 2000) |
| myocardia | Plural of myocardium. (05 Mar 2000) |
| myocardial | Refers to the heart's muscle mass. (09 Oct 1997) |
| myocardial biopsy | <procedure> A procedure which involves the removal of a small specimen of cardiac muscle tissue for microscopic analysis. This is generally performed at the same time as a cardiac catheterisation or as a very similar, yet separate, procedure. A small piece of heart tissue is taken via a small forceps inserted into the cardiac catheter site (usually threaded through a vein in the neck). This test may reveal the cause of a cardiomyopathy, myocarditis, amyloidosis or a heart transplant rejection. (27 Sep 1997) |
| myocardial bridge | A bridge of cardiac muscle fibres extending over the epicardial aspect of a coronary artery; this finding, in cases of sudden unexpected death, has led to speculation that cardiac contraction during exertion could constrict the coronary artery. (05 Mar 2000) |
| myocardial contraction | Contractile activity of the heart. (12 Dec 1998) |
| myocardial contusion | A bruise to the heart muscle, usually caused by a blunt force applied to the anterior thorax (motor vehicle accident). Commonly seen in association with a rib or sternum fracture. Complications include cardiac arrhythmias and death. (27 Sep 1997) |
| myocardial depressant factor | A low molecular weight peptide of about 800-1000 having a negative inotropic effect. It is released into the circulation during experimental haemorrhagic pancreatitis, severe ischemia, and postoligaemic shock. (12 Dec 1998) |
| myocardial diseases | Diseases of the myocardium. (12 Dec 1998) |
| myocardial infarct imaging | <radiology> Tc-99m pyrophosphate (PYP) 20 mCi, peak abnormality 2-3 days, often falsely negative before 2 days, abnormal for 7-10 days, mechanism: calcium influx into ischemic cells, PYP incorporated into crystalline structure, analogous to hydroxyapatite see: nuclear cardiology (12 Dec 1998) |
| myocardial infarction | A term used to describe irreversible injury to heart muscle. Synonym: heart attack. See: infarction. Common symptoms include substernal, crushing chest pain that may radiate to the jaw or arms. Chest pains may be associated with nausea, sweating and shortness of breath. Acronym: MI (27 Sep 1997) |
| myocardial infarction in dumbbell form | Infarction involving the septum along with both inferior and anterior walls to make an H-or dumbbell-shaped configuration. Synonym: Roesler-Bressler infarct. (05 Mar 2000) |
| myocardial insufficiency | A condition where there is ineffective pumping of the heart leading to an accumulation of fluid in the lungs. Typical symptoms include shortness of breath with exertion, difficulty breathing when lying flat and leg or ankle swelling. Causes include chronic hypertension, cardiomyopathy and myocardial infarction. (27 Sep 1997) |
| myocardial ischemia | A disorder of cardiac function caused by insufficient blood flow to the muscle tissue of the heart. The decreased blood flow may be due to narrowing of the coronary arteries (coronary arteriosclerosis), to obstruction by a thrombus (coronary thrombosis), or less commonly, to diffuse narrowing of arterioles and other small vessels within the heart. Severe interruption of the blood supply to the myocardial tissue may result in necrosis of cardiac muscle (myocardial infarction). (12 Dec 1998) |
