  • Acetylcholine Receptor

    1. GENERAL INFORMATION ABOUT ACETYLCHOLINE Acetylcholine (ACh) is one of the first neurotransmitters to be discovered and Otto Loewi first described is as ‘vagus stuff’ as it is able to mimic the electrical stimulation of vagus nerve. Acetylcholine is produced by the enzyme choline acetyltransferase‚ using acetyl coenzyme A (acetyl CoA) and dietary choline as substrates. Acetylcholine and the interaction with its target have played a critical role in the basic concepts of neurochemistry. Chemical

  • Additional True Neurotransmitters

    which is not part of a ring structure. Among the amine neurotransmitters are acetylcholine‚ norepinephrine‚ dopamine‚ and serotonin. Acetylcholine is possibly the most widely used neurotransmitter in the body‚ and all axons that leave the central nervous system (for example‚ those running to skeletal muscle‚ or to sympathetic or parasympathetic ganglia) use acetylcholine as their neurotransmitter. Within the brain acetylcholine is the transmitter of‚ among other neurons‚ those generating the tracts

  • Compare And Contrast The Two Types Of Excitatory Transmitters

    The types of excitatory transmitters that could be brought on are dopamine‚ norepinephrine‚ epinephrine or acetylcholine‚ and glutamate. Each one of these is used for something different in the body and include a different process. Like stated before‚ these types of transmitters are transmitted through chemical messengers to the brain. Since we are talking about acetylcholine and dopamine‚ those both have very different functions for the body. One deals with motor skills and memory while the

  • Exocytosis and the Neuromuscular Junction

    matrix and collagen (Etherington & Hong‚ 2011). Acetylcholine is an important aspect in neuromuscular junction. It is used to transmit signals to muscles to initiate contractions or movement of the muscles. The toxin binds to neurons where it separates. One part cleaves a protein ultimately preventing the deduction process necessary for the release of acetylcholine (Gill‚ 2004). Botulinum toxin‚ BOTOX‚ disrupts the release of acetylcholine so when signals are released to muscles‚ they can’t attach

  • Scopolamine

    criminal. Scopolamine affects the memory and makes people more passive. Scopolamine competes with our acetylcholine which is a brain chemical. Memories work through this chemical. Acetylcholine is a compound that occurs throughout the nervous system‚ in which it functions as a neurotransmitter. When scopolamine competes with acetylcholine‚ scopolamine wins the battle and blocks the acetylcholine receptor in the brain. Therefore‚ making memories is impossible when consuming this drug. Also‚ scopolamine
