| 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. |

|---|---|---|---|
| 설명 | 얼굴의 피부를 움직이고 이에 부착되어 있는 얼굴신경의 공급을 받는 수많은 근육을 포함하는 얼굴표정근이나 모방근. |

| ciliary canals | Irregularly shaped endothelium-lined spaces within the trabecular reticulum, through which the aqueous filters to reach the sinus venosus sclerae. Synonym: spatia anguli iridocornealis, ciliary canals, Fontana's spaces. (05 Mar 2000) |
|---|---|
| ciliary cartilage | Incorrect term sometimes applied to the inferior tarsus and superior tarsus. See: tarsus. (05 Mar 2000) |
| ciliary crown | The circular figure on the inner surface of the ciliary body, formed by the processes and folds (plicae) taken together. Synonym: ciliary crown, ciliary wreath. (05 Mar 2000) |
| ciliary disk | The darkly pigmented posterior zone of the ciliary body continuous with the retina at the ora serrata. Synonym: ciliary disk, ciliary ring, pars plana. Origin: Mod. L. (05 Mar 2000) |
| ciliary folds | A number of low ridges in the furrows between the ciliary processes; together with the processes they constitute the corona ciliaris. Synonym: plicae ciliares. (05 Mar 2000) |
| ciliary ganglion | <anatomy, neurology> Neural crest derived ganglion acting as relay between parasympathetic neurons of the oculomotor nucleus in the midbrain and the muscles regulating the diameter of the pupil of the eye. (18 Nov 1997) |
| ciliary ganglionic plexus | An autonomic plexus lying on the ciliary muscle, derived from the oculomotor, trigeminal, and sympathetic. Synonym: plexus gangliosus ciliaris. (05 Mar 2000) |
| ciliary glands | A number of modified apocrine sudoriferous glands in the eyelids, with ducts that usually open into the follicles of the eyelashes. Synonym: glandulae ciliares, Moll's glands. (05 Mar 2000) |
| ciliary ligament | <anatomy> The smooth muscle of the ciliary body; it consists of circular fibres (Muller's muscle) and radiating fibres (meridional fibres, or Brucke's muscle); action, in contracting, its diameter is reduced (like a sphincter), reducing tensile (stretching) forces on lens, allowing it to thicken for near vision (accommodation). Synonym: musculus ciliaris, Bowman's muscle, ciliary ligament. (05 Mar 2000) |
| ciliary margin of iris | The peripheral border of the iris attached to the ciliary body. Synonym: margo ciliaris iridis, ciliary margin of iris. (05 Mar 2000) |
| ciliary motility disorders | Disorders characterised by abnormal ciliary movement in the nose, paranasal sinuses, respiratory tract, and spermatozoa. Electron microscopy of the cilia shows that dynein arms are missing. The disorders manifest as kartagener triad (kartagener's syndrome), chronic respiratory disorders, chronic sinusitis, and/or chronic otitis. (12 Dec 1998) |
| ciliary movement | The rhythmic, sweeping movement of epithelial cell cilia, of ciliate protozoans, or the sculling movement of flagella, effected possibly by the alternate contraction and relaxation of contractile threads (myoids) on one side of the cilium or flagellum. (05 Mar 2000) |
| ciliary neurotrophic factor | <growth factor> Neurotrophic factor originally characterised as a survival factor for chick ciliary neurons in vitro. Subsequently shown to promote the survival of a variety of other neuronal cell types and to promote the differentiation of bipotential O2A progenitor cells to type 2 astrocytes in vitro. Molecular cloning and expression studies indicate that CNTF is a cytosolic protein. Developmental expression and regional distribution studies show that, unlike NGF, CNTF is not a target derived neurotrophic factor. (18 Nov 1997) |
| ciliary part of retina | ciliary part of retina |
| ciliary process | One of the radiating pigmented ridges, usually seventy in number, on the inner surface of the ciliary body, increasing in thickness as they advance from the orbiculus ciliaris to the external border of the iris; these, together with the folds (plicae) in the furrows between them, constitute the corona ciliaris. Synonym: processus ciliaris. (05 Mar 2000) |
