| 영문 | sympathetic nervous system | 한글 | 교감신경계 |
|---|---|---|---|
| 설명 | 자율신경계의 일종으로 내장기능을 주로 항진시켜 활동을 증가시키는 기능을 가진다. 자율신경계의 다른 계열인 부교감신경계는 반대로 내장기능을 억제시켜 에너지를 비축하는 기능을 가진다. 자율신경계의 해부학적 특성은 신경이 중추신경계에서 나와 목표장기에 도달하기 전에 한번의 시냅스(synapse)를 이룬다는 점이며, 따라서 자율신경계는 두 개의 신경(시냅스를 이루기 전의 절전신경과 이룬 후의 절후신경)으로 구성된다. 자율신경계중 교감신경계는 중추신경계 즉 척수 부근의 교감신경절(sympathetic ganglion)에서 시냅스가 일어나고, 부교감 신경계는 중추신경계에서 멀리 떨어진 목표 장기부근의 신경절(ganglion)에서 시냅스가 일어나는 점이 다르다. |

| gamma benzene hexachloride | <chemical> One of the purified isomers of hexachlorobenzene which is used as a scabicide and pediculicide applied topically to the skin in various lotions, creams, and shampoos; gamma benzene hexachloride can be absorbed through the skin. Resembles DDT in its actions but is less persistent. Incorrect name for 1,2,3,4,5,6-hexachlorocyclohexane (lindane). Synonym: hexachlorocyclohexane. Acronym: GBH (05 Mar 2000) |

| gamma-butyrobetaine | Gamma-(Trimethylammonium) butyric acid;a betaine of gamma-aminobutyric acid; a precursor of carnitine by hydroxylation of the beta-carbon. (05 Mar 2000) |
| gamma camera | Any one of several scintigraphic cameras that records simultaneously counts from the entire operative field of view. Synonym: scintillation camera. (05 Mar 2000) |
| gamma cameras | Electronic instruments that produce photographs or cathode-ray tube images of the gamma-ray emissions from organs containing radionuclide tracers. (12 Dec 1998) |
| gamma cell of pancreas | A cell of the pancreatic islets of the guinea pig. Synonym: gamma cell of pancreas. Synonym: parafollicular cells. (05 Mar 2000) |
| gamma crystallin | The least rapidly mobile form of crystallin on electrophoresis. (05 Mar 2000) |
| gamma-cyanoaminobutyrate synthase | <enzyme> Homocystine + 2cn- yields gamma-cyanobutyric acid + scn-+ homocysteine; pyridoxal-5-phosphate dependent Registry number: EC 4.- (26 Jun 1999) |
| gamma-cystathionase | <enzyme> A multifunctional pyridoxal phosphate enzyme. In the final step in the biosynthesis of cysteine it catalyses the cleavage of cystathionine to yield cysteine, ammonia, and 2-ketobutyrate. Chemical name: L-Cystathionine cysteine-lyase (deaminating) Registry number: EC 4.4.1.1 (12 Dec 1998) |
| gamma efferent | The thin axon of a gamma motor neuron innervating the intrafusal muscle fibres of a muscle spindle. (05 Mar 2000) |
| gamma emission | <physics> Nuclear decay process whereby the nucleus goes from an excited state to a more stable state by emitting a gamma ray. See: gamma ray. (09 Oct 1997) |
| gamma encephalography | Imaging of the encephalon by the administration of small amounts of gamma-emitting radionuclides; commonly called a brain scan; superseded by computed tomography and magnetic resonance imaging. (05 Mar 2000) |
| gamma-endorphin | <chemical> An endogenous opioid peptide derived from the pro-opiomelanocortin precursor peptide. It differs from alpha-endorphin by one amino acid. Chemical name: gamma-Endorphin (12 Dec 1998) |
| gamma fibres | Nerve fibre's that have a conduction rate of about 20 m/sec. See: gamma efferent. (05 Mar 2000) |
| gamma globulin | <immunology> A non-specific immunoglobulin (antibody) administered for the purpose of passive immunity. A common example is hepatitis A prophylaxis. (27 Sep 1997) |
| gamma-globulins | Serum globulins that migrate in the gamma region on electrophoresis. At one time, gamma-globulins came to be used as a synonym for immunoglobulins since most immunoglobulins are gamma globulins. But since some immunoglobulins exhibit an alpha or beta electrophoretic mobility, that usage is in decline. (12 Dec 1998) |
