Acetylcholine is the neurotransmitter used at the neuromuscular junction—in other words, it is the chemical that motor neurons of the nervous system release in order to activate muscles.

Acetylcholine is a neurotransmitter that plays a role in memory, learning, attention, arousal and involuntary muscle movement. Medical conditions associated with low acetylcholine levels include Alzheimer’s disease and myasthenia gravis. Researchers still need more studies to determine if choline supplements provide health benefits.

乙酰胆碱（英语： Acetylcholine, ACh ，分子式CH 3 CO O CH 2 CH 2 N + (CH 3) 3 ）为中枢及周边神经系统中常见的神经传导物质，于自主神经系统及体运动神经系统中参与神经传导。

2023年4月10日 · Acetylcholine is a neurochemical that has a wide variety of functions in the brain and other organ systems of the body. Specifically, it is a neurotransmitter that acts as a chemical message that is released by neurons and allows them to communicate with one another and other specialized cells such as myocytes and cells found in glandular tissues.

2025年3月21日 · Acetylcholine is a neurotransmitter that acts within the central and peripheral nervous systems. It is the chief neurotransmitter of the parasympathetic nervous system, which contracts smooth muscles, dilates blood vessels, increases bodily …

乙酰胆碱，分子式CH3COOCH2CH2N+（CH3）3，是一种 神经递质。 在组织内迅速被 胆碱酯酶 破坏。 乙酰胆碱能特异性地作用于各类胆碱 受体，但其作用广泛，选择性不高。 临床不作为药用，一般只做实验用药。 在神经细胞中，乙酰胆碱是由胆碱和 乙酰辅酶A 在胆碱乙酰移位酶（胆碱乙酰化酶）的 催化作用 下合成的。 主流研究认为人体内该物质含量增多与 阿尔兹海默病 （老年痴呆症）的症状改善显著相关。 乙酰胆碱，分子式CH3COOCH2CH2N+（CH3）3在神经细胞 …

Acetylcholine, the first neurotransmitter discovered, was originally described as "vagus stuff" by Otto Loewi because of its ability to mimic the electrical stimulation of the vagus nerve. It is now known to be a neurotransmitter at all autonomic ganglia, at many autonomically innervated organs, at the neuromuscular junction, and at many ...

Acetylcholine in vertebrates is the major transmitter at neuromuscular junctions, autonomic ganglia, parasympathetic effector junctions, a subset of sympathetic effector junctions, and at many sites in the central nervous system.

乙酰胆碱(acetylcholine)，英文简称ACh。 乙酰胆碱是一种传出神经系统递质，作用位置为全部交感神经和副交感神经的节前纤维，运动神经，全部副交感神经的节后纤维，和极少数交感神经的节后纤维。

2020年3月31日 · While acetylcholine supplements don’t exist, you can take supplements that may indirectly raise acetylcholine levels. This article explores the benefits and side effects of acetylcholine...
