| 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. |

| superficial branch of the transverse cervical artery | <anatomy, artery> Branch of transverse cervical artery which accompanies the spinal accessory nerve on the deep surface of the trapezius muscle. Alternatively arises as a direct branch of the thyrocervical trunk, in which case it is called the superficial cervical artery. (05 Mar 2000) |
|---|---|
| superficial cervical artery | <anatomy, artery> Origin, branch of thyrocervical trunk, running with spinal accessory nerve deep to trapezius muscle. See: superficial branch of the transverse cervical artery. Synonym: arteria cervicalis superficialis. (05 Mar 2000) |
| superficial circumflex iliac artery | <anatomy, artery> Origin, femoral; distribution, inguinal lymph nodes and integument of that region; sartorius, and tensor fasciae latae muscles; anastomoses, deep circumflex iliac. Synonym: arteria circumflexa iliaca superficialis. (05 Mar 2000) |
| superficial epigastric artery | <anatomy, artery> Origin, femoral; distribution, inguinal nodes and integument of lower abdomen; anastomoses, inferior epigastric, superficial circumflex iliac and external pudendal. Synonym: arteria epigastrica superficialis. (05 Mar 2000) |
| superficial temporal artery | <anatomy, artery> Origin, a terminal branch of the external carotid (with maxillary artery); branches, transverse facial, middle temporal, orbital, parotid, anterior auricular, frontal, and parietal. Synonym: arteria temporalis superficialis. (05 Mar 2000) |
| superficial volar artery | <anatomy, artery> The superficial palmar branch of the radial artery which supplies the thenar muscles then enters the palm to communicate with the superficial palmar arch from the ulnar artery. Synonym: ramus palmaris superficialis arteriae radialis, superficial palmar artery, superficial volar artery, superficialis volae. (05 Mar 2000) |
| frontal branch of superficial temporal artery | <anatomy, artery> Terminal branch of superficial temporal artery (with parietal branch) supplying anterolateral scalp and underlying musculature, periosteum, and outer table of cranium; anastomosis: across midline with contralateral partner; supratrochlear and supraorbital arteries. Synonym: ramus frontalis arteriae temporalis superficialis. (05 Mar 2000) |
| palmar | 1. <anatomy> Pertaining to, or corresponding with, the palm of the hand. 2. <ornithology> Of or pertaining to the under side of the wings of birds. Origin: L. Palmaris, fr. Palma the palm of the hand: cf. F. Palmaire. Source: Websters Dictionary (01 Mar 1998) |
| palmar aponeurosis | The thickened, central portion of the fascia ensheathing the hand; it radiates toward the bases of the fingers from the tendon of the palmaris longus muscle. Synonym: aponeurosis palmaris, Dupuytren's fascia, palmar fascia. (05 Mar 2000) |
| palmar branch of median nerve | <anatomy, nerve> Branch of median nerve arising proximal to flexor retinaculum and running superficial to it to supply skin of proximal central palm and thenar eminence. Since it does not traverse carpal tunnel, it is not affected by carpal tunnel syndrome, even though it supplies skin distal to carpal tunnel. Synonym: ramus palmaris nervi mediani. (05 Mar 2000) |
| palmar branch of ulnar nerve | <anatomy, nerve> Branch of ulnar nerve arising in distal forearm and accompanying palmar artery into hand where it supplies skin of little finger and medial half of ring finger and adjacent parts of palm. Synonym: ramus palmaris nervi ulnaris. (05 Mar 2000) |
| palmar carpal ligament | Thickening of distal antebrachial fascia just proximal to radiocarpal (wrist) joint. Continuous with extensor retinaculum at margins of forearm. This structure is distinct from the transverse carpal ligament, commonly called "the flexor retinaculum," which forms the roof of the carpal tunnel. Synonym: flexor retinaculum of forearm, palmar carpal ligament. (05 Mar 2000) |
| palmar carpometacarpal ligaments | Fibrous bands that connect the palmar surfaces of the carpal and metacarpal bones. Synonym: ligamentum carpometacarpalia palmaria. (05 Mar 2000) |
| palmar crease | Any of the several flexion crease's normally found on the palm of the hand, occurring proximal to, but as a consequence of flexion at, the metacarpophalangeal joints. (05 Mar 2000) |
| palmar digital veins | Paired venae comitantes of the proper and common digital arteries that empty into the superficial palmar venous arch. Synonym: venae digitales palmares. (05 Mar 2000) |
