| 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. |

| cardiac blood pool imaging | This noninvasive test uses radioactive tracers to delineate the hearts chambers and major vessels. It may be used to detect a heart attack, heart muscle function and coronary artery disease. The patient receives a radioactive tracer by injection (into a vein) and then the heart is imaged using a gamma camera. The heart is imaged before and after exercise. This test may be used to detect and evaluate atrial septal defect, dilated cardiomyopathy, congestive heart failure, cardiomyopathy, Lyme disease (secondary), mitral stenosis and superior vena cava syndrome. (27 Sep 1997) |
| cardiac care facilities | Institutions specializing in the care of patients with heart disorders. (12 Dec 1998) |
| cardiac catheter | <cardiology> A catheter that can be passed into the heart through a vein or artery, to withdraw samples of blood, measure pressures within the heart's chambers or great vessels, and inject contrast media. It is used mainly in the diagnosis and evaluation of congenital, rheumatic, and coronary artery lesions and to evaluate systolic and diastolic cardiac function. Synonym: cardiac catheter. (05 Mar 2000) |
| cardiac catheterisation | Cardiac catheterisation has given physicians the opportunity to directly diagnose and ascertain the extent of coronary artery occlusive disease. Using this procedure, physicians can make more accurate decisions concerning the best form of treatment for each patients condition. Cardiac catheterisation involves the placement of a thin flexible, hollow tube into the femoral artery in the groin. From here, the catheter is advanced under X-ray guidance (fluoroscopy) through the aorta to the heart. Radiopaque contrast, injected into the coronary arteries (as they branch off the aorta) will serve to highlight the course of these vessels when an X-ray is performed. Any coronary blockage or narrowing can be detected using this procedure. (27 Sep 1997) |
| cardiac cell | Strictly speaking any cell of or derived form the cardium of the heart, but often used loosely of heart cells. (18 Nov 1997) |
| cardiac cirrhosis | An extensive fibrotic reaction within the liver as a result of chronic constrictive pericarditis or prolonged congestive heart failure; true cirrhosis with fibrous bridging of lobules is unusual. Synonym: cardiac liver, congestive cirrhosis, pseudocirrhosis, stasis cirrhosis. (05 Mar 2000) |
| cardiac competence | Ability of the ventricles to pump the blood returning to the atria, so that atrial pressure does not rise abnormally. (05 Mar 2000) |
| cardiac complexes, premature | Premature contractions of the heart that are independent of the normal rhythm and arise in response to an impulse in some part of the heart other than the sinoatrial node. (12 Dec 1998) |
| cardiac contractility | A measure of cardiac pump performance, the degree to which muscle fibres can shorten when activated by a stimulus independent of preload and afterload. (05 Mar 2000) |
| cardiac cycle | The complete round of cardiac systole and diastole with the intervals between, or commencing with, any event in the heart's action to the moment when that same event is repeated. (05 Mar 2000) |
| cardiac decompression | Incision into the pericardium or aspiration of fluid from pericardium to relieve pressure due to blood or other fluid in the pericardial sac. Synonym: pericardial decompression. (05 Mar 2000) |
| cardiac depressor reflex | A fall in blood pressure due to peripheral vasodilation and cardiac inhibition by stimulations of terminations of a cardiac depressor nerve in the aortic arch and base of the heart. Synonym: aortic reflex, depressor reflex. (05 Mar 2000) |
| cardiac diuretic | A diuretic which acts by increasing function of the heart, and thereby improves renal perfusion. (05 Mar 2000) |
| cardiac dropsy | Oedema due to heart failure. (05 Mar 2000) |
