| 설명 | 체내의 신경 세포에서 방출되며 인접하는 신경세포나 근육에 정보를 전달하는 물질. 신경세포내에서 합성되어서 신경종말의 연접소포에 저장된다. 자극에 의해서 연접간극에 유리되어서 수용체와 결합하여 정보를 다음 세포로 전한다. 전기적으로가 아니라 화학물질에 의해서 연접간극을 거쳐 정보를 전하기 때문에 화학전달물질이라고도 한다. 연접후막(경우에 따라서 연접전막)을 흥분(탈분극)시키는 흥분성전달물질과 억제(과분극)하는 억제성 전달물질이 있다. 아세틸콜린, 노르에피네프, 도파민, 글리신, γ-아미노뷰칠산(GABA)등 같은 신경전달물질이라도 수용체에 따라서 흥분성과 억제성으로도 작용하는 것도 있다. |

neurotransmitter |
Any of a group of substances that are released on excitation from the axon terminal of a presynaptic neuron of the central or peripheral nervous system and travel across the synaptic cleft to either excite or inhibit the target cell. Among the many substances that have the properties of a neurotransmitter are acetylcholine, noradrenaline, adrenaline, dopamine, glycine, y aminobutyrate, glutamic acid, substance P, enkephalins, endorphins and serotonin. (18 Nov 1997) |

neurotransmitter agents |
Substances used for their pharmacological actions on any aspect of neurotransmitter systems. Neurotransmitter agents include agonists, antagonists, degradation inhibitors, uptake inhibitors, depleters, precursors, and modulators of receptor function. (12 Dec 1998) |
neurotransmitter system |
A group of nerve cells that use the sameneurotransmitter to communicate. (22 May 1997) |
neurotransmitter uptake inhibitors |
Drugs that inhibit the transport of neurotransmitters into axon terminals or into storage vesicles within terminals. For many transmitters, uptake determines the time course of transmitter action so inhibiting uptake prolongs the activity of the transmitter. Blocking uptake may also deplete available transmitter stores. Many clinically important drugs are uptake inhibitors although the indirect reactions of the brain rather than the acute block of uptake itself is often responsible for the therapeutic effects. (12 Dec 1998) |
neurotransmitters |
Endogenous signaling molecules that alter the behaviour of neurons or effector cells. Neurotransmitter is used here in its most general sense, including not only messengers that act directly to regulate ion channels, but also those that act through second messenger systems, and those that act at a distance from their site of release. Included are neuromodulators, neuroregulators, neuromediators, and neurohumors, whether or not acting at synapses. (12 Dec 1998) |
neurotransmitters and neurotransmitter agents |
A collective grouping for neurotransmitters and substances that act on the neurotransmitter system. (12 Dec 1998) |

neurotransmitter
|
A chemical that is released from a nerve cell, which transmits an impulse from that nerve cell to another nerve cell, or to another organ (a muscle, for example). Neurotransmitters are chemical messengers that transmit neurological information from one cell to another.
