| 영문 | alimentary canal | 한글 | 소화관 |
|---|---|---|---|
| 설명 | 입에서 항문에 이르는 음식의 소화-흡수에 관여하는 관상 또는 확대되어 낭상으로 된 부분의 총칭. 소화기관 중 소화샘을 제외한 것이다. 고등척추동물에서는 구강→인두→식도→들문→위→날문→작은창자(샘창자→돌창자)→큰창자(잘룩창자→곧창자)→항문까지 하나로 잊는 관으로 작은창자 말단부와 큰창자가 시작되는 곳의 접점에는 막창자이 연결된다. 구강에서 위에 이르는 소화관의 전반부에서는 ① 음식의 섭취와 그 확보, ② 씹는 일, ③ 음식의 저류가 이루어지는 데, 소화는 구강 안에서의 침 속의 프티알린에 의한 녹말 일부의 분해, 위에서의 펩신에 의한 단백질 일부의 분해뿐이며, 흡수는 알코올 및 알코올에 녹은 물질이 위벽에서 흡수될 뿐이다. |

| 영문 | neural canal | 한글 | 신경관 |
|---|---|---|---|
| 설명 | 척추에서 척수가 내려가는 통로. 이외에도 신경이 지나가는 막힌 통로에 해당하는 곳은 모두 신경관으로 부른다. 예를 들어 손의 감각과 운동을 담당하는 자뼈신경(ulnar nerve)이 지나가는 곳에 존재하는, 뼈와 주위조직에 둘러싸인 곳을 Guaon's canal(ulnar neural canal)이라 부른다. 대개 이런 곳은 주위조직의 부종이나, 외상 등으로 좁아지기 쉬어서 병터가 발생하기 쉽다. |

| anus | <anatomy> The distal or terminal orifice of the alimentary canal. (18 Nov 1997) |
| anus cerebri | Entrance to the cerebral aqueduct (of Sylvius) from the caudal part of the third ventricle. Synonym: aditus ad aqueductum cerebri, Bartholin's anus, opening to cerebral aqueduct. (05 Mar 2000) |
| anus, imperforate | Persistence of the anal membrane, so that the anus is closed. The defect is not always complete; sometimes a narrow opening permits the passage of the bowel contents. When completely imperforate, the anus is seen as a dimple (the proctodeal pit) in the skin of the perineum. The latter condition is often associated with atresia of the lower rectum. (12 Dec 1998) |
| anus vesicalis | Rectal emptying into the urinary bladder. (05 Mar 2000) |
| artificial anus | An opening into the bowel, usually in the right or left flank, as a result of a colostomy. (05 Mar 2000) |
| Bartholin's anus | Entrance to the cerebral aqueduct (of Sylvius) from the caudal part of the third ventricle. Synonym: aditus ad aqueductum cerebri, Bartholin's anus, opening to cerebral aqueduct. (05 Mar 2000) |
| vesicalis anus | Imperforate anus with urinary bladder opening into the anus. (05 Mar 2000) |
| vestibular anus | <anatomy, surgery> A congenital malformation in which the anus is imperforate but the rectum opens into the vagina just above the vulva. (05 Mar 2000) |
| corrugator cutis muscle of anus | Smooth muscle fibres radiating from the anal opening superficial to the external sphincter. Synonym: musculus corrugator cutis ani. (05 Mar 2000) |
| imperforate anus | <embryology, paediatrics> A congenital obstruction of the anal opening. Occurs in approximately 1 in 5,000 infants. This condition is corrected through surgery. (27 Sep 1997) |
| internal sphincter muscle of anus | <anatomy> A smooth muscle ring, formed by an increase of the circular fibres of the rectum, situated at the upper end of the anal canal, internal to the outer voluntary external anal sphincter. This sphincter is maximally-contracted when the rectal ampulla is at rest -empty or relaxed to accommodate a distending faecal mass. It is inhibited with filling of the ampulla, increased distension and peristalsis. Synonym: musculus sphincter ani internus, internal sphincter muscle of anus. (05 Mar 2000) |
| elevator muscle of anus | <anatomy> Formed by pubococcygeus and iliococcygeus muscles; origin, posterior body of pubis, tendinous arch of the levator ani, and spine of ischium; insertion, anococcygeal ligament, sides of the lower part of the sacrum and of coccyx; action, resists prolapsing forces and draws the anus upward following defecation; supports the pelvic viscera; nerve supply, nerve to levator ani (fourth sacral spinal nerve). Synonym: musculus levator ani, elevator muscle of anus. (05 Mar 2000) |
| external sphincter muscle of anus | A fusiform ring of striated muscular fibres surrounding the anus, attached posteriorly to the coccyx and anteriorly to the central tendon of the perineum; it is subdivided, often indistinctly, into a subcutaneous part, a superficial part and a deep part for descriptive purposes. Synonym: musculus sphincter ani externus, external sphincter muscle of anus. (05 Mar 2000) |
| anal | <anatomy> Pertaining to the anus. (18 Nov 1997) |
