| 설명 | 특이한 생산물을 만들어 세포 밖으로 내보내는 세포의 활동 또는 그 생산물을 말한다. 예를 들어 이자세포는 소화효소인 이자액을 만들어 분비하는 데, 이 때 이자액을 분비물이라 함. |

| 설명 | 생물에 작용하여 특정의 반응을 일으키는 요인. 보통 외계의 조건 변화에 따라 생물체에 특유한 활동이 왕성해지는 것을 생물체가 흥분했다고 하며, 흥분을 일으키는 원인이 된 외계의 조건 변화를 자극이라고 한다. 예를 들면, 바늘 끝으로 손등을 찌르면 신경섬유에 자극을 주게 되어, 이 신경섬유에 충격이라고 하는 어떤 변화가 생긴다. 이 충격이 전도되어 간다. 이 상태를 신경섬유가 흥분했다고 한다. 외적조건의 변화가 이것에 대응하는 감각기가 수용하여 자극이 되는데, 자극에 대한 반응에 반사적으로 일어나는 눈깜박이와 같은 국부적인 것이 있고, 기온의 변화에 대해서와 같이 전신적인 것도 있다. 세포자극으로서 작용하는 외계의 조건 변화는 그 에너지의 종류에 따라 기계적 자극-화학적 자극-온열적 자극-삼투압 자극-전기적 자극 등이 있다. 그 중 전기적 자극은 생체 속에서 자연히 일어나는 자극과 그로 인해 일어나는 흥분이 모두 전기적 과정이므로 자연히 일어나는 자극과 같거나, 그것에 가까운 것이다. 어떤 종류의 조건 변화는 도리어 흥분을 일으키기 어렵게 하는 것도 있다. |

| stimulus secretion coupling | A term used to describe the events that link receipt of a stimulus with the release of materials from membrane bounded vesicles (the analogy is with excitation contraction coupling in the control of muscle contraction). A classical example is the link between membrane depolarisation at the presynaptic terminal and the release of neurotransmitter into the synaptic cleft. (18 Nov 1997) |

| glands of internal secretion | Ductless glands that secrete substances which are released directly into the circulation and which influence metabolism and other body functions. (12 Dec 1998) |
|---|---|
| cytocrine secretion | The transfer of secretory material from one cell to another, such as the transfer of melanin granules from melanocytes to epidermal cells. (05 Mar 2000) |
| secretion | 1. <physiology> The process of elaborating a specific product as a result of the activity of a gland, this activity may range from separating a specific substance of the blood to the elaboration of a new chemical substance. 2. Any substance produced by secretion. Origin: L. Secretio, from secernere = to secrete (09 Oct 1997) |
| secretion vector | <molecular biology> A DNA vector in which the protein product is both expressed and secreted (excreted) from the cell. (09 Oct 1997) |
| neurohumoral secretion | Transmission of a nerve impulse across a synapse or to an end-organ by secretion of a minute amount of a chemical transmitter such as acetylcholine. (05 Mar 2000) |
| syndrome of inappropriate secretion of antidiuretic hormone | Continued secretion of antidiuretic hormone despite low serum osmolality and expanded extracellular volume. (05 Mar 2000) |
| external secretion | A substance formed by a cell and transported outside the cell walls as a means of ridding the cell of the substance or as a messenger to affect the function of other cells. (05 Mar 2000) |
| viscous mechanical coupling | <cell biology> Method by which adjacent cilia are synchronised in a field. Coupling is through the transmission of mechanical forces, rather than of a synchronising signal. (18 Nov 1997) |
| chemiosmotic coupling | The linking of ATP synthesis to electrontransfer by way of an electrochemical hydrogen cation gradient across amembrane. (09 Oct 1997) |
| metabolic coupling | <cell biology, molecular biology> Transfer between tissue cells in contact of low molecular weight metabolites such as nucleotides and amino acids. Transfer is via channels constituted by the connexons of gap junctions and does not involve exchange with the extracellular medium. First observed in cultures of animal cells in which radio labelled purines were transferred from wild type cells to mutants unable to utilise exogenous purines. (27 Jun 1999) |
| constant coupling | Where several premature beats are seen, the interval between each of them and the preceding normal beat is constant. Synonym: constant coupling. Variable coupling, where several extrasystoles are seen, the interval between each of them and the preceding sinus beat varies. (05 Mar 2000) |
| coupling | <biochemistry> The linking of two independent processes by a common intermediate, for example the coupling of electron transport to oxidative phosphorylation or the ATP ADP conversion to transport processes. (18 Nov 1997) |
| coupling defect | See: familial goiter. (05 Mar 2000) |
| coupling factor | Protein responsible for coupling transmembrane potentials to ATP synthesis in chloroplasts and mitochondria. Include ATP synthesising enzymes (F1 in mitochondrion), that can also act as ATP ases. (18 Nov 1997) |
| coupling factors | Proteins that restore phosphorylating ability to mitochondria that have lost it, i.e., have become "uncoupled" so that oxidation and electron transport no longer produces ATP. Usually termed coupling factor F1, F2, etc. Synonym: C factors. (05 Mar 2000) |
