| 설명 | 머리의 생김새를 외형으로 나타내는 머리의 골격을 이루는 뼈. 사람의 경우 23개가 있는데, 특징은 팔다리의 긴뼈의 일반적 형태와 달리 딱딱한 치밀뼈가 바깥쪽을 이루며 그 사이에 생긴 해면뼈가 존재하는 형태이다. 구성은 뇌를 간직하고 있는 위쪽의 뇌머리뼈와 얼굴을 구성하는 아래쪽의 얼굴머리뼈(viscerocranium)로 구성되며 뇌머리뼈는 윗부분의 머리덮개뼈(calvaria)와 아래쪽의 머리뼈 바닥으로 구분된다. 머리의 구성뼈는 모두 28개이며, 그 중 머리뼈를 구성하고 있는 것은 22개이고, 한 개는 혀 밑에 있는 목뿔뼈이며, 나머지 여섯 개는 귓속에 있는 고실뼈이다. 머리뼈를 구성하는 뼈는 다음과 같다. 1. 머리뼈.① 뇌머리뼈:마루뼈, 관자뼈, 이마뼈, 벌집뼈, 나미뼈, 뒤통수뼈. ② 얼굴머리뼈:코뼈, 눈물뼈, 하비갑개, 입천장뼈, 광대뼈, 보습뼈, 위턱뼈, 아래턱뼈. 2. 혀의 뼈:목뿔뼈. 3. 고실뼈:망치뼈, 모루뼈, 등자뼈. 기능은 뇌를 간직하며 보호하는 역할을 하고 눈, 귀, 코, 입 등의 감각기관이 들어갈 공간을 마련해주며 몸속으로 출입하는 호흡기와 소화기의 입구가 있으며 일부 뼈에는 치아라는 구조물을 갖추고 있어 음식을 씹는 기능을 수행한다. 머리뼈에서는 입을 움직이는 턱관절을 제외하고는 뼈와 뼈사이가 관절운동을 할 수 없는 형태의 섬유상 관절로 되어 있다. 섬유상 관절에는 봉합, 못박이관절(gomphosis), 인대결합(syndesmosis)의 세 종류가 있다.  |

| patch clamp | <physiology> A specialised and powerful variant of voltage clamping, in which a patch electrode of relatively large tip diameter (5m) is pressed tightly against the plasma membrane of a cell, forming an electrically tight, gigohm seal. The current flowing through individual ion channels can then be measured. Different variants on this technique allow different surfaces of the plasma membrane to be exposed to the bathing medium: the contact just described is a cell attached patch. If the electrode is pulled away, leaving just a small disc of plasma membrane occluding the tip of the electrode, it is called an inside out patch. If suction is applied to a cell attached patch, bursting the plasma membrane under the electrode, a whole cell patch (similar to an intracellular recording) is formed. If the electrode is withdrawn from the whole cell patch, the membrane fragments adhering to the electrode reform a seal across the tip, forming an outside out patch. (15 Mar 2000) |
| patch-clamp techniques | An electrophysiologic technique for studying cells, cell membranes, and occasionally isolated organelles. All patch-clamp methods rely on a very high-resistance seal between a micropipette and a membrane; the seal is usually attained by gentle suction. The four most common variants include on-cell patch, inside-out patch, outside-out patch, and whole-cell clamp. Patch-clamp methods are commonly used to voltage clamp, that is control the voltage across the membrane and measure current flow, but current-clamp methods, in which the current is controlled and the voltage is measured, are also used.

| Payr's clamp | A clamp used in gastrectomy or enterectomy. (05 Mar 2000) |
| glucose clamp technique | <technique> Maintenance of a constant blood glucose level by perfusion or infusion with glucose or insulin. It is used for the study of metabolic rates (e.g., in glucose, lipid, amino acid metabolism) at constant glucose concentration. (12 Dec 1998) |
| voltage clamp | <physiology, technique> A technique in electrophysiology, in which a microelectrode is inserted into a cell and current injected through the electrode so as to hold the cells membrane potential at some predefined level. The technique can be used with separate electrodes for voltage sensing and current passing, for small cells, the same electrode can be used for both. Voltage clamp is a powerful technique for the study of ion channels. See: patch clamp. (18 Nov 1997) |
