  2. Acetylcholine - Wikipedia

    en.wikipedia.org/wiki/Acetylcholine

    Acetylcholine is the primary neurotransmitter of the parasympathetic nervous system. [2] [3] In the brain, acetylcholine functions as a neurotransmitter and as a neuromodulator. The brain contains a number of cholinergic areas, each with distinct functions; such as playing an important role in arousal, attention, memory and motivation. [4]

  3. Choline acetyltransferase - Wikipedia

    en.wikipedia.org/wiki/Choline_acetyltransferase

    The protein encoded by this gene synthesizes the neurotransmitter acetylcholine. Acetylcholine acts at two classes of receptors in the central nervous system – muscarinic and nicotinic – which are each implicated in different physiological responses. The role of acetylcholine at the nicotinic receptor is still under investigation.

  4. Synaptic vesicle - Wikipedia

    en.wikipedia.org/wiki/Synaptic_vesicle

    Later, synaptic vesicles could also be isolated from other tissues such as the superior cervical ganglion, [40] or the octopus brain. [41] The isolation of highly purified fractions of cholinergic synaptic vesicles from the ray Torpedo electric organ [42] [43] was an important step forward in the study of vesicle biochemistry and function.

  5. Neurotransmitter - Wikipedia

    en.wikipedia.org/wiki/Neurotransmitter

    An antagonist is a chemical that acts within the body to reduce the physiological activity of another chemical substance (such as an opiate); especially one that opposes the action on the nervous system of a drug or a substance occurring naturally in the body by combining with and blocking its nervous receptor.

  6. Choline - Wikipedia

    en.wikipedia.org/wiki/Choline

    Choline is used to synthesize acetylcholine, a neurotransmitter involved in muscle control and numerous functions of the nervous system. [2] [3] Choline is involved in early development of the brain, gene expression, cell membrane signaling, and brain metabolism. [3]

  7. Basal forebrain - Wikipedia

    en.wikipedia.org/wiki/Basal_forebrain

    These structures are important in the production of acetylcholine, which is then distributed widely throughout the brain. The basal forebrain is considered to be the major cholinergic output of the central nervous system (CNS) centred on the output of the nucleus basalis. [1]

  8. End-plate potential - Wikipedia

    en.wikipedia.org/wiki/End-plate_potential

    Acetylcholine is synthesized in the cytoplasm of the neuron from choline and acetyl-CoA. Choline acetyltransferase is the enzyme that synthesizes acetylcholine and is often used as a marker in research relating to acetylcholine production. Neurons that utilize acetylcholine are called cholinergic neurons and they are very important in muscle ...

  9. Choline transporter - Wikipedia

    en.wikipedia.org/wiki/Choline_transporter

    Choline is a direct precursor of acetylcholine (ACh), a neurotransmitter of the central and peripheral nervous system that regulates a variety of autonomic, cognitive, and motor functions. SLC5A7 is a Na(+)- and Cl(-)- dependent high-affinity transporter that mediates the uptake of choline for acetylcholine synthesis in cholinergic neurons. [5] [6]
