Drugs and substances that interrupt acetylcholine function can have negative effects on the body since they affect the heart, nerves, brain and muscles. In severe cases, symptoms and complications can even be deadly. These drugs are capable of altering ACh levels and leading to symptoms as a res...
a short-acting neurotransmitter, widely distributed in the body, that functions as a nervous system stimulant, a vasodilator, and a cardiac depressant. Abbr.:ACh [1905–10] a•ce`tyl•cho•lin′ic(-ˈlɪn ɪk)adj. Random House Kernerman Webster's College Dictionary, © 2010 K...
Partly because of its muscle-activating function, but also because of its functions in the autonomic nervous system and brain, many important Drugs exert their effects by altering cholinergic transmission. Numerous venoms and toxins produced by plants, animals, and bacteria, as well as chemical nerve...
There are five different types of muscarinic receptors, M1, M2, M3, M4, and M5. All these subtypes are metabotropic receptors, contrasting them from the nicotinic type of acetylcholine receptors. Furthermore, each subtype is either stimulatory or inhibitory. Subtypes M1, M3, and M5 function thro...
Function of acetylcholine Now let us look at the functions of acetylcholine. In both the central nervous system and the peripheral nervous system, acetylcholine has a function. In both of them, it acts as a neuromodulator (a neuron using one or more neurotransmitters to control other neurons)....
Both nicotinic and muscarinic receptors are found throughout the CNS. Cholinergic neurons in the striatum are involved in the control of motor function. In other CNS regions, there is evidence that cholinergic neurons are involved in memory and learning, and play a critical role in the sleep–wa...
Mammalian Nicotinic Acetylcholine Receptors: From Structure to Function The classical studies of nicotine by Langley at the turn of the 20th century introduced the concept of a "receptive substance," from which the idea of a "r... EX Albuquerque,EFR Pereira,M Alkondon,... - 《Physiological ...
Acetylcholine's function in the body can be disrupted by a variety of causes, including disease and toxins. Imbalances in this important neurotransmitter can lead to a number of health consequences, many of which impact memory and muscle control. Some of these conditions involve the depletion of ...

THE well-known work of Prof. O. Loewi and of Sir Henry Dale and their collaborators has established the widespread function of acetylcholine as a chemical transmitter of nervous action. It has further been established that there exists in the animal organism a specific enzyme, choline-esterase, ...
