| 설명 | 심장동맥이란 심장에 혈액을 공급하는 동맥을 말한다. 심장도 다른 근육과 마찬가지로 혈액을 공급받아야 수축을 할 수가 있는 기관으로 심장의 혈액을 공급하는 동맥을 심장동맥이라고 한다. 심장동맥병이란 심장동맥의 내경이 좁아져서 생기는 질환으로 허혈심장병(ischemic heart disease)이라고도 불린다. 관상동맥이 좁아질 경우에는 심장으로 가는 혈액의 양이 적어져서 심장에 충분한 혈액이 공급이 되지 못하므로 여러 가지 병적인 현상이 생긴다. 심장동맥이 좁아지는 데에는 여러 가지 원인이 있을 수가 있으나 주로 심장동맥의 동맥경화증에 의한다. 동맥경화증이란 동맥의 내층에 지방과 콜레스테롤로 이루어진 죽종(atheroma)가 생기는 질환으로 죽종이 생긴 동맥은 죽종이 혈관의 내부로 돌출하게 되어서 혈관의 내경이 작아지게 된다. 심장동맥병은 그 정도에 따라서 협심증(angina pectoris)와 심근경색증(myocardial infarction)으로 나눈다. 협심증은 심장동맥의 부분적 폐쇄에 의해서 평상시에는 증상이 없지만 심장이 많은 활동을 할 경우에 심장에 피가 충분한 만큼 공급이 되지 않아서 생기는 질병으로 평상시에 쉴 경우에는 아무 증상이 없지만 운동이나 과식 등의 원인으로 심장이 많은 운동을 할 경우에 심장에 공급되는 혈액의 양이 모자라서 증상(대개 가슴부위에 쥐어짜는 듯한 통증)이 생긴다. 심근경색증이란 심장동맥의 완전폐쇄에 의해서 심장의 근육이 혈액을 전혀 공급받지 못해서 심장의 근육이 썩는 경우를 말한다. |

| menisci, tibial | Crescent-shaped disks of fibrocartilage attached to the superior articular surface of the tibia. (12 Dec 1998) |
| second tibial muscle | An inconstant muscle, of small size, arising from the back of the tibia and inserted into the articular capsule of the ankle joint. Synonym: second tibial muscle. (05 Mar 2000) |
| subcutaneous bursa of tibial tuberosity | The bursa located superficial to the tibial tuberosity, either subcutaneous or subfascial. Synonym: bursa subcutanea tuberositatis tibiae. (05 Mar 2000) |
| superior tibial articulation | The plane synovial joint between the lateral condyle of the tibia and the head of the fibula. Synonym: articulatio tibiofibularis, superior tibial articulation, superior tibiofibular joint, tibiofibular articulation. (05 Mar 2000) |
| tibial | 1. Of or pertaining to a tibia. 2. Of or pertaining to a pipe or flute. <zoology> Tibial spur, a spine frequently borne on the tibia of insects. Origin: L. Tibialis, fr. Tibia the shin bone; also, a pipe or flute, originally made of a bone: cf. F. Tibial. <anatomy> A tibial bone; a tibiale. Source: Websters Dictionary (01 Mar 1998) |
| tibial arteries | The anterior and posterior arteries created at the bifurcation of the popliteal artery. The anterior tibial artery begins at the lower border of the popliteus muscle and lies along the tibia at the distal part of the leg to surface superficially anterior to the ankle joint. Its branches are distributed throughout the leg, ankle, and foot. The posterior tibial artery begins at the lower border of the popliteus muscle, lies behind the tibia in the lower part of its course, and is found situated between the medial malleolus and the medial process of the calcaneal tuberosity. Its branches are distributed throughout the leg and foot. (12 Dec 1998) |
| tibial border of foot | The inner border of the foot extending from heel to the great toe. Synonym: margo medialis pedis, margo tibialis pedis, tibial border of foot. (05 Mar 2000) |
| tibial bowing | <radiology> Anterior bowing, OI, hypophosphatasia, thanatophoric dwarfism, neurofibromatosis, may lead to if fractured, doesn't heal normally, posterior bowing, often bilateral, due to foetal malposition, fracture will heal normally (12 Dec 1998) |
| tibial collateral ligament | <anatomy> The broad fibrous band that passes from the medial epicondyle of the femur to the medial margin and medial surface of the tibia; the medial meniscus is attached to its deep surface; it is continuous with (a thickening of) the fibrous capsule of the knee joint. Synonym: ligamentum collaterale tibiale, medial ligament of knee. (05 Mar 2000) |
| tibial communicating nerve | <anatomy, nerve> Arises from the tibial in the popliteal space, passes down the calf between the two heads of the gastrocnemius and unites in the middle of the leg with the communicating branch of the common peroneal to form the sural nerve, distributed to the skin of the distal and lateral surfaces of the leg and ankle. Synonym: nervus cutaneus surae medialis, medial cutaneous nerve of leg, popliteal communicating nerve, tibial communicating nerve. (05 Mar 2000) |
| tibial crest | The sharp subcutaneous ridge of the tibia that extends from the tuberosity to the anterior part of the medial malleolus. Synonym: margo anterior tibiae, anticnemion, shin, tibial crest. (05 Mar 2000) |
| tibial intertendinous bursa | <anatomy> The bursa between the tibial collateral ligament of the knee joint and the tendons of the sartorius, gracilis, and semitendinosus muscles. Synonym: bursa anserina, tibial intertendinous bursa. (05 Mar 2000) |
| tibial nerve | <anatomy, nerve> The medial terminal branch of the sciatic nerve. The tibial nerve fibres originate in lumbar and sacral spinal segments (l4 to s2). They supply motor and sensory innervation to parts of the calf and foot. (12 Dec 1998) |
| tibial phenomenon | Dorsal flexion of the great toe, sometimes of the entire foot, in a paralysed limb when the extremity is drawn up against the body, flexing both knee and hip. Synonym: tibial phenomenon. (05 Mar 2000) |
