| 영문 | smooth muscle | 한글 | 민무늬근육, 평활근육 |
|---|---|---|---|
| 설명 | 근육 중에서 가로무늬가 없는 근. 가로무늬근에 대응되는 말이다. 척추동물에서는 심장근 이외의 내장근은 모두가 민무늬근이다. 많은 내장장기의 벽에 분포되어 있으며, 대개 돌림층과 세로층의 두 층으로 배열되어 있다. 소화관이나 요관 같은 관모양의 구조에서는 꿈틀운동을 일으켜 내용물이 아래로 내려가게 하는 작용을 한다. 항문관, 위, 요도 등에서는 돌림층의 근육이 특히 두꺼워져 내용물이 내려가는 것을 조절하는 조임근육이 형성되어 있다. 혈관에는 돌림층만 있으며, 혈관을 수축하여 혈액을 쥐어짜는 작용을 한다. 또한 자율신경의 지배를 받으며, 우리의 의지와 관계없이 작용한다. |

| 영문 | voluntary muscle | 한글 | 수의근 |
|---|---|---|---|
| 설명 | 의지의 힘으로 움직일 수 있는 근육. 골격근 외에 피부 내의 피근, 관절주머니에 부착하고 있는 관절근 등이 여기에 속한다. 수의근의 근섬유에는 가로무늬가 있으므로 가로무늬근이라고도 하나, 심장근은 가로 무늬가 있어도 수의근이 아니므로 수의근과 가로무늬근은 동의어는 아니다. 수의근의 운동은 민무늬근보다 빠르다. 수의근이라 해도 골격근 등은 근육무리로서 움직일 수 있으나, 개개의 근육은 따로따로 마음대로 움직이게 할 수 없다. 귓바퀴근육은 사람의 경우 발육이 나빠 마음대로 움직이게 하기 어렵다. |

| processus transversus | A bony protrusion on either side of the arch of a vertebra, from the junction of the lamina and pedicle, which functions as a lever for attached muscles. Synonym: processus transversus. (05 Mar 2000) |
|---|---|
| sinus transversus | A paired dural venous sinus that drains the confluence of sinuses, running along the occipital attachment of the tentorium cerebelli and terminating in the sigmoid sinus. Synonym: sinus transversus, lateral sinus. Transverse pericardial sinus, a passage in the pericardial sac between the origins of the great vessels, i.e., posterior to the intrapericardial portions of the pulmonary trunk and ascending aorta and anterior to the superior vena cava and superior to the atria; it is formed as a result of the flexure of the heart tube, partially approximating the great venous and arterial vessels. Synonym: sinus transversus pericardii, Theile's canal, transverse sinus of pericardium. (05 Mar 2000) |
| sinus transversus pericardii | transverse pericardial sinus |
| situs transversus | <disease> Condition in which the normal asymmetry of the body (in respect of circulatory system and intestinal coiling) is reversed. Interesting because it occurs in approximately 50% of patients with immotile cilia syndrome, a disorder of ciliary dynein. (10 Oct 1997) |
| nervus transversus colli | <anatomy, nerve> A branch of the cervical plexus that supplies the skin over the anterior triangle of the neck. Synonym: nervus transversus colli, cutaneous cervical nerve, nervus cervicalis superficialis, superficial cervical nerve, transverse nerve of neck. (05 Mar 2000) |
| sulcus anthelicis transversus | A deep groove on the cranial surface of the auricle separating the eminences of the triangular fossa and of the concha. Synonym: sulcus anthelicis transversus. (05 Mar 2000) |
| sulcus occipitalis transversus | The posterior, vertical limb of the intraparietal sulcus. Synonym: sulcus occipitalis transversus. (05 Mar 2000) |
| transversus | Synonym: transverse. Origin: L. Fr. Trans, across, + verto, pp. Versus, to turn (05 Mar 2000) |
| transversus abdominis | <anatomy, muscle> Origin, seventh to twelfth costal cartilages, lumbar fascia, iliac crest, and inguinal ligament; insertion, xiphoid cartilage and linea alba and, through the conjoint tendon, pubic tubercle and pecten; action, compresses abdominal contents; nerve supply, lower thoracic. Synonym: musculus transversus abdominis, musculus transversalis abdominis, transverse muscle of abdomen. (05 Mar 2000) |
| transversus thoracis | <anatomy, muscle> Origin, dorsal surface of xiphoid cartilage and lower portion of dorsal surface of body of sternum; insertion, second to sixth costal cartilages; action, contributes to depression of ribs, narrowing chest; nerve supply, intercostal. Synonym: musculus transversus thoracis, musculus triangularis sterni, sternocostalis muscle, transverse muscle of thorax. (05 Mar 2000) |
| tubulus transversus | A tubular invagination of the sarcolemma of skeletal or cardiac muscle fibres that surrounds myofibrils as the intermediate element of the triad; involved in transmitting the action potential from the sarcolemma to the interior of the myofibril. (05 Mar 2000) |
| abdominal external oblique muscle | <anatomy, muscle> Origin, fifth to twelfth ribs; insertion, anterior half of lateral lip of iliac crest, inguinal ligament, and anterior layer of the rectus sheath; action, diminishes capacity of abdomen, draws thorax downward; nerve supply, thoracoabdominal nerves. Synonym: musculus obliquus externus abdominis, abdominal external oblique muscle. (05 Mar 2000) |
| abdominal internal oblique muscle | <anatomy, muscle> Origin, iliac fascia deep to lateral part of inguinal ligament, anterior half of crest of ilium, and lumbar fascia; insertion, tenth to twelfth ribs and sheath of rectus; some of the fibres from inguinal ligament terminate in the conjoint tendon; action, diminishes capacity of abdomen, flexes lumbar vertebral column (bends thorax forward); nerve supply, lower thoracic. Synonym: musculus obliquus internus abdominis, abdominal internal oblique muscle. (05 Mar 2000) |
| abdominal muscle deficiency syndrome | <syndrome> Congenital absence (partial or complete) of abdominal muscles, in which the outline of the intestines is visible through the protruding abdominal wall; in males, genitourinary anomalies (urinary tract dilation and cryptorchidism) are also found; genetics unclear. (05 Mar 2000) |
| abductor digiti minimi muscle of foot | Origin, lateral and medial processes of calcanean tuberosity; insertion, lateral side of proximal phalanx of fifth toe; action, abducts and flexes little toe; nerve supply, lateral plantar nerve. Synonym: musculus abductor digiti minimi pedis, abductor muscle of little toe, musculus abductor digiti quinti. (05 Mar 2000) |
