| 영문 | muscle | 한글 | 근육 |
|---|---|---|---|
| 설명 | 의식의 조절여부에 따라 수의근(의식에 의해서 조절이 가능한 근육: 예를 들어 다리, 팔, 얼굴근육 등)과 불수의근(의식과 무관하게 조절하지 않아도 움직이는 근육: 예를 들어 심장근, 소화기관에 분포하는 근육 등)으로 나누어질 수 있으며, 또한 심장근이 따로 존재한다. |

| 영문 | muscle biopsy | 한글 | 근육생검 |
|---|---|---|---|
| 설명 | 생체내에서 근육에 대한 질병의 감별진단을 위해서 실시하는 검사법. 방법은 병터가 있는 부위나 혹은 없어도 크게 활동에 지장이 없는 근육부위의 조직을 떼어 현미경적으로 검사한다. 예를 들어 신경조직의 이상으로 인한 근육병터의 경우, 근육생검을 하여 관찰해보면 이른바 “무리진 위축(grouped atrophy)”이 나타나서, 다른 병터에 의한 것과 감별이 가능하다. |

| 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. |

| cochlear hair cell | <anatomy> The sound sensing cell of the inner ear. The cells have modified ciliary structures (hairs), that enable them to produce an electrical (neural) response to mechanical motion caused by the effect of sound waves on the cochlea. Frequency is detected by the position of the cell in the cochlea and amplitude by the magnitude of the disturbance. (18 Nov 1997) |
|---|---|
| cochlear hair cells | Sensory cell's in the organ of Corti in synaptic contact with sensory as well as efferent fibres of the cochlear (auditory) nerve; from the apical end of each cell about 100 stereocilia extend from the surface and make contact with the tectorial membrane. Synonym: Corti's cells. (05 Mar 2000) |
| pigmented hair epidermal nevus | A nevus first seen as an irregular pigmentation of the shoulders, upper chest, or scapular area, gradually enlarging irregularly and becoming thickened and hairy. Synonym: pigmented hair epidermal nevus. (05 Mar 2000) |
| moniliform hair | An autosomal dominant trichodystrophy in which brittle hairs show a series of constrictions, usually without a medulla. Synonym: beaded hair, moniliform hair. Origin: L. Monile, necklace, + G. Thrix, hair (05 Mar 2000) |
| woolly hair | Tightly coiled hair, oval in cross-section, with the texture of wool. (05 Mar 2000) |
| woolly-hair nevus | A circumscribed patch of fine, curly hair in an otherwise normal scalp appearing during childhood and enlarging for a period of 2 to 3 years; autosomal dominant inheritance. There is another, mostly sporadic form that may be autosomal recessive. Synonym: allotrichia circumscripta. (05 Mar 2000) |
| cortex of hair shaft | The principal structural component of the hair shaft, composed of closely packed fusiform keratinised cells and invested by the cuticula pili. (05 Mar 2000) |
| hair | 1. The collection or mass of filaments growing from the skin of an animal, and forming a covering for a part of the head or for any part or the whole of the body. 2. One the above-mentioned filaments, consisting, in invertebrate animals, of a long, tubular part which is free and flexible, and a bulbous root imbedded in the skin. "Then read he me how Sampson lost his hairs." (Chaucer) "And draweth new delights with hoary hairs." (Spenser) 3. Hair (human or animal) used for various purposes; as, hair for stuffing cushions. 4. <zoology> A slender outgrowth from the chitinous cuticle of insects, spiders, crustaceans, and other invertebrates. Such hairs are totally unlike those of vertebrates in structure, composition, and mode of growth. 5. An outgrowth of the epidermis, consisting of one or of several cells, whether pointed, hooked, knobbed, or stellated. Internal hairs occur in the flower stalk of the yellow frog lily (Nuphar). 6. A spring device used in a hair-trigger firearm. 7. A haircloth. 8. Any very small distance, or degree; a hairbreadth. Hairs is often used adjectively or in combination; as, hairbrush or hair brush, hair dye, hair oil, hairpin, hair powder, a brush, a dye, etc, for the hair. Against the hair, in a rough and disagreeable manner; against the grain. "You go against the hair of your professions." . <anatomy> Hair bracket, the thinnest metal space used in lines of type. Hair stroke, a delicate stroke in writing. Hair trigger, a trigger so constructed as to discharge a firearm by a very slight pressure, as by the touch of a hair. Not worth a hair, of no value. To a hair, with the nicest distinction. To split hairs, to make distinctions of useless nicety. Origin: OE. Her, heer, haer, AS. Haer; akin to OFries, her, D. & G. Haar, OHG. & Icel. Har, Dan. Haar, Sw. Har; cf. Lith. Kasa. Source: Websters Dictionary (01 Mar 1998) |
| hair ball | A hair cast in the stomach or intestinal tract, common in cats. Synonym: hair ball, pilobezoar. Origin: tricho-+ bezoar (05 Mar 2000) |
| hair bulb | Hair bulb, the lower expanded extremity of the hair follicle that fits like a cap over the papilla pili. Synonym: bulbus pili, hair bulb. (05 Mar 2000) |
| hair cast | 1. A cast composed of parakeratotic scales attached to scalp hair but freely movable up and down the hair shaft; found in scaling dermatitis of the scalp, including dandruff, psoriasis, and seborrheic dermatitis. Synonym: pseudonit. 2. A small, nodular accretion of epithelial cells and keratinous debris resulting from failure of the internal root sheath to disintegrate; it appears for 3 to 7 mm along the hair shaft. (05 Mar 2000) |
| hair cell | 1. <biology> Cells found in the epithelial lining of the labyrinth of the inner ear. The hairs are stereovilli up to 25 m long that restrict the plane in which deformation of the apical membrane of the cell can be brought about by movement of fluid or by sound. Movement of the single stereocilium transduces mechanical movements into electrical receptor potentials. 2. <plant biology> Many plant surfaces are covered with fine hairs (Tradescantia stamens are a common source), the hairs are made up of thin walled cells that are convenient for studying cytoplasmic streaming and for observing mitosis. (13 Nov 1997) |
| hair cells | Mechanoreceptors located in the organ of corti that are sensitive to auditory stimuli and in the vestibular apparatus that are sensitive to movement of the head. In each case the accessory sensory structures are arranged so that appropriate stimuli cause movement of the hair-like projections (stereocilia and kinocilia) which relay the information centrally in the nervous system. (12 Dec 1998) |
| hair cells, inner | Bulbous cells that are medially placed in one row in the organ of corti. In contrast to the outer hair cells, the inner hair cells are fewer in number, have fewer sensory hairs, and are less differentiated. (12 Dec 1998) |
| hair cells, outer | Mechanoreceptors in the organ of corti. In mammals the outer hair cells are arranged in three rows which are further from the modiolus than the single row of inner hair cells. The motile properties of the outer hair cells may contribute actively to tuning the sensitivity and frequency selectivity of the cochlea. (12 Dec 1998) |
