| 설명 | 사람몸에 존재하는 체액에는 2가지가 있는데, 하나가 피이고 또 다른 하나가 림프이다. 이 두 가지 모두 사람 몸속에 존재하는 각 세포들에 대해 영양을 공급하고, 대사작용을 하도록 해주며, 이 때 생기는 노폐물을 옮기는 역할을 한다. 피는 골수에서 생성되어 혈관으로 나오게 되면, 심장의 펌프작용으로 전신을 돌아 다니게 된다. 이렇게 해서 동맥으로 들어간 피가 각 기관의 세포에 이르게 되면, 각 세포에서 서로 산소와 영양분을 교환한 뒤, 정맥으로 나오게 된다. 이 때 일부의 체액은 세포 사이사이에 남게 되는데, 이것을 사이질액(interstitial fluid)이라 부르고 이 간질액이 특별한 얇은 림프모세혈관으로 나오게 되면, 이제서야 이 간질액은 림프라고 불리게 된다. 따라서 림프액은 성분은 피와 같다고는 할 수 없지만, 같은 곳에서 기원한다고 볼 수 있다. 림프액의 성분은 피보다는 단백질 성분이 적고, 대신에 지방성분이 많으며, 피속에 있는 적혈구나 혈소판은 없는 대신에 림프구와 단핵구가 많다. 림프관은 혈관계에 의해 이동될 수 없는 너무 고장성의 액체의 이동이나, 소화기관에 의해 넘어온 영양분의 이동에 이용되어진다. 또한 림프를 따라가다 보면 림프절를 만날 수 있는데 이곳에서는 림프구가 많이 존재하여 면역반응을 나타내게 된다. |

|---|---|---|---|
| 설명 | 각 림프 모세관을 통해 모아진 림프액은 들림프관(afferent lymphatic vessels)을 따라 여러 림프절로 모이게 된다. 림프절에서는 림프액이 이른바 림프구로 가득찬 1차종자결절(primary germinal nodule)과 큰포식세포로 가득 찬 동굴그물을 거치게 되어서, 나쁜 병균이나 기타 이물이 면역작용을 받게되어 인체에 무해하도록 정화되어진다. 이렇게 정화된 림프액은 다시 날림프관(efferent lymphatic vessel)을 통해 다른 림프절이나 림프관으로 이동되어 결국은 가슴관(thoracic ducts)을 통해 정맥과 만나 심장으로 보내어지게 된다. 따라서 림프의 주행을 보면 다음과 같다. 간질액→림프모세관(lymphatic capillary)→들림프관→림프절→날림프관→이중 일부(주로 우측팔에 있는 림프액)는 우측 림프관으로 나머지 대부분은 가슴관(thoracic duct)으로 모여져 심장으로 감. 이러한 림프절은 인체 내에 아주 많이 존재하며, 그중 큰 것은 각기 그 위치에 따라 이름이 붙여져 있다. 악성종양이 발생시 그 전이의 형태는 혈액을 통한 혈관계 전이와 림프를 통한 림프관계전이를 통해 이루어진다. 따라서 어떤 알 수 없는 종양에서 주위 림프절의 크기가 커져 있으면, 그 종양은 악성을 의미한다고 할 수 있다. 하지만, 림프절은 단지 알 수 없는 불특정 감염에서도 면역작용에 의해 그 크기가 커지게 되므로, 림프절의 크기증가가 꼭 악성을 의미하는 것은 아니다.   |

| calcium channel | <physiology> A membrane channel that is specific for calcium. It is a voltage-dependent cell membrane glycoproteins selectively permeable to calcium ions. They are categorised as l, t, n, or p types based on the activation and inactivation kinetics, ion specificity, and sensitivity to drugs and toxins. (12 May 2002) |
|---|---|
| calcium channel agonist | <pharmacology> Agents that increase calcium influx into calcium channels of excitable tissues. This causes vasoconstriction in vascular smooth muscle and/or cardiac muscle cells as well as stimulation of insulin release from pancreatic islets. Therefore, tissue-selective calcium agonists have the potential to combat cardiac failure and endocrinological disorders. They have been used primarily in experimental studies in cell and tissue culture. (12 Dec 1998) |
| calcium channel antagonist | <pharmacology> A class of drugs that act by selective inhibition of calcium ion influx through or across cell membranes or on the release and binding of calcium in intracellular pools. Calcium channel blockers are used primarily in the treatment of certain heart conditions and stroke. As they are inducers of vascular and other smooth muscle relaxation, they are also used in the treatment of hypertension and cerebrovascular spasms, as myocardial protective agents, and in the relaxation of uterine spasms. Synonym: calcium antagonist, calcium channel-blocker, slow channel-blocking agent. (12 May 2002) |

| gated ion channel | <physiology> Transmembrane proteins of excitable cells, that allow a flux of ions to pass only under defined circumstances. Channels may be either voltage gated, such as the sodium channel of neurons or ligand gated such as the acetylcholine receptor of cholinergic synapses. Channels tend to be relatively ion specific and allow fluxes of typically 1000 ions to pass in around 1ms, they are thus much faster at moving ions across a membrane than transport ATPases. (05 May 1997) |
| voltage-gated channel | A class of ion channel's that open and close in response to change in the electrical potential across the plasma membrane of the cell; voltage-gated Na+ c.'s are important for conducting action potential along nerve cell processes. (05 Mar 2000) |
| voltage gated ion channel | <physiology> A transmembrane ion channel whose permeability to ions is extremely sensitive to the transmembrane potential difference. These channels are essential for neuronal signal transmission and for intracellular signal transduction. See: sodium channel. (18 Nov 1997) |
| channel | A furrow, gutter, or groovelike passageway. See: canal. Origin: L. Canalis (05 Mar 2000) |
| channel forming ionophore | <chemistry> An ionophore that makes an amphipathic pore with hydrophobic exterior and hydrophilic interior. most known types are cation selective. (18 Nov 1997) |
| channel gating | <physiology> Small currents in the membrane just prior to the increase in ionic permeability, due to the movement of charged particles within the membrane. So called because they open the gates for current flow through ion channels. (20 Mar 1998) |
| channel islands | A group of four british islands and several islets in the english channel off the coast of france. They are known to have been occupied prehistorically. They were a part of normandy in 933 but were united to the british crown at the time of the norman conquest in 1066. Guernsey and jersey originated noted breeds of cattle. (12 Dec 1998) |
| channel protein | <chemistry, physiology> A protein that facilitates the diffusion of molecules/ions across lipid membranes by forming a hydrophilic pore. most frequently multimeric with the pore formed by subunit interactions. (18 Nov 1997) |
| channel transport | <radiobiology> In inertial fusion research using light ion drivers, describes the use of current-carrying plasma channels (which are magnetically confined to the channel) to transport electron or ion beams between the ion diode and the fusion target. This allows the ion source to stand back from the target. (09 Oct 1997) |
| chloride channel | Ion channels selective for chloride ions. Various types including ligand activated Cl channels at synapses (the GABA and glycine activated channels), as well as voltage gated Cl channels found in a variety of plant and animal cells. See: CFTR, MDR. (18 Nov 1997) |
| ryanodine receptor calcium release channel | Protein complexes that mediate the release of calcium from the sarcoplasmic reticulum in both skeletal and cardiac muscle cells by forming tetrametric complexes. These complexes each then act as a calcium channel. There are three isoforms of the ryr: ryr1, ryr2, and ryr3. Ryr1 is specifically expressed in skeletal muscles and ryr2 in cardiac muscles. Ryr3 is yet another isoform found in non-muscle cells such as neuronal cells. (12 Dec 1998) |
