Acetylcholine (ACh): What It Is, Function & Deficiency - Cleveland Clinic
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.

5 天之前 · Acetylcholine is the chief neurotransmitter of the parasympathetic nervous system, the part of the autonomic nervous system (a branch of the peripheral nervous system) that contracts smooth muscles, dilates blood vessels, increases bodily secretions, and slows heart rate.
How Acetylcholine Functions in Your Body - Verywell Mind
2023年5月30日 · Acetylcholine (ACh) is a chemical that plays an important role in many different body functions. It is a neurotransmitter, and its main role is to communicate signals between neurons in the central nervous system (CNS) and the peripheral nervous system (PNS).
Acetylcholine - Wikipedia
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 - Physiopedia
Acetylcholine is a critical neurotransmitter that plays an important role in the normal function of the brain and body. Disruptions in the release and function of this neurotransmitter can result in significant problems in areas such as memory and movement.
Acetylcholine Neurotransmission (Section 1 ... - Texas Medical …
In this chapter we will discuss the acetylcholine’s anatomy, cell biology, physiological effects, role in behavior, and clinical applications. In the autonomic nervous system, acetylcholine (ACh) is the neurotransmitter in the preganglionic sympathetic and parasympathetic neurons. These are shown in Figure 11.2 as the red ACh in the ganglion.
Acetylcholine - an overview | ScienceDirect Topics
Acetylcholine is the endogenous neurotransmitter at cholinergic synapses and neuromuscular junctions in the central and peripheral nervous systems. Acetylcholine is involved in control of behavioral state, posture, cognition and memory, and the autonomous parasympathetic (and preganglionic sympathetic) nervous system.
Acetylcholine: Function, Associated Conditions, and More
2023年3月23日 · Acetylcholine is a neurotransmitter found in the central nervous system (CNS) and peripheral nervous system (PNS). It plays an important role in many of your body's functions, including muscle movement, memory and cognition, REM sleep, and attention and learning.
What Is Acetylcholine? Definition, Functions, and More
2022年4月25日 · Acetylcholine is an amino acid that acts as a neurotransmitter. Neurotransmitters send messages from one neuron to another in your nervous system. As one of the most plentiful neurotransmitters, acetylcholine plays a role in literally every move you make and every breath you take.
