Critical Care Nurse, 1990
Abstract Acetylcholine is used as a chemical transmitter at several parts of the peripheral and central nervous systems that are crucial for the functioning of the autonomic nervous system. The preganglionic neurons of both divisions of the autonomic nervous system release acetylcholine as their neurotransmitter; it is also used by ...

Acetylcarnitine and Cholinergic Receptors
Journal of Pharmaceutical Sciences, 1980Acetylcarnitine, a naturally occurring compound found in high concentration in heart and skeletal muscle of vertebrates, bears structural resemblance to acetylcholine, and studies have shown that it has slight cholinergic properties. Acetylcarnitine was subjected to conformational analysis by extended Hückel theory (EHT) and complete neglect of ...

Cholinergic Receptors and Addiction
2020Human behavior can be controlled by physical or psychological dependencies associated with addiction. One of the most insidious addictions in our society is the use of tobacco products which contain nicotine. This addiction can be associated with specific receptors in the brain that respond to the natural neurotransmitter acetylcholine. These nicotinic

Cholinergic innervation and receptors in the cerebellum.
Progress in brain research, 1997We have studied the source and ultrastructural characteristics of ChAT-immunoreactive fibers in the cerebellum of the rat, and the distribution of muscarinic and nicotinic receptors in the cerebellum of the rat, rabbit, cat and monkey, in order to define which of the cerebellar afferents may use ACh as a neurotransmitter, what target structures are ...

Cholinergic receptors and neurodegenerative diseases
Pharmaceutica Acta Helvetiae, 2000Publisher Summary This chapter focuses on cholinergic receptors and neurodegenerative diseases. Known as the “cholinergic hypothesis of Alzheimer's disease (AD),” this hypothesis has served as the main rationale for the development of anti-AD drugs, even if alternative approaches, such as the use of neurotrophic agents, nootropics, glutamate ...

Cholinergic receptors in corpora cavernosa
Urology, 1984In a group of 13 patients who underwent penile surgery, a small amount of cavernosal tissue was removed and examined for content of cholinergic receptors. Three patients did not display any amount of cholinergic receptors. Values in the other 10 patients ranged from 34 to 136 femtomols.

Immunohistochemistry of cholinergic receptors
Anatomy and Embryology, 1992Acetylcholine and its receptors are involved in a variety of important signal transduction processes. As shown here paradigmatically for the human neuromuscular junction and the cerebral cortex, acetylcholine receptors can be visualized immunohistochemically at the cellular and subcellular level under physiological and pathological conditions.

Studies on the nature of the cholinergic receptor
European Journal of Pharmacology, 1968Abstract The effects of a number of proteolytic enzymes on the acetylcholine sensitivity of the chronically deniervated musue membrane and on the cholinesterase activity of the innervated end-plate were examined. None of the enzymes affected the acetylcholine sensitivity, but all of them inactivated cholinesterase.

Presynaptic muscarinic cholinergic receptors
Nature, 1978IN the isolated rabbit heart, acetylcholine inhibits the release of noradrenaline evoked by nicotinic drugs1, by KCl (ref. 2) and by sympathetic nerve stimulation3. The release of noradrenaline in response to sympathetic nerve stimulation in the rabbit heart was found to be reduced by para-sympathomimetic agonists, and atropine antagonised this effect ...

Cholinergic receptors in the Aplysia gill
Journal of Neurobiology, 1984AbstractAcetylcholine has been suggested as a neurotransmitter released in the Aplysia gill by peripheral afferents of central neurons and by peripheral neurons within the gill. The perfused gill, isolated from the abdominal ganglion, was examined. At concentrations greater than 1 μM, acetylcholine elicited a slowly developing tonic contraction of the ...
