What nerve connects the spine to the brain? Explain the functions of each. What effect does bending of the stereocilia have on the stimulation of action potentials from the support afferent neurons? How does acetylcholine affect blackworm muscle cells, and how does this, in turn, affect black...
Acetylcholine: Acetylcholine is the main neurotransmitter released within the parasympathetic nervous system. This enzyme is produced from acetyl CoA and choline by the enzyme choline acetyltransferase. Answer and Explanation: Acetylcholine will first b...
This is due to pilocarpine acting as an agonist of acetylcholine. Figures 7 and 8 show this effect. Atropine affects the same receptor pilocarpine does, but has the opposite outcome. The chemical atropine serves as an antagonist to acetylcholine and this causes an increase in heart rate. This ...
How does acetylcholine affect the pacemaker cells of the heart? How does heart disease affect homeostasis? What are the health benefits of regular aerobic exercise? Explain two reasons why the coronary circulation is more efficient when the heart is relaxed. Describe the cardiac cycle and explain ...
For example, acetylcholine is a neurotransmitter that has an effect on movement by being released to muscle cell receptors that cause muscles to contract. Researchers have found that the brain produces its own opiates and therefore certain drugs can trigger them. The problem with this is that the...
How does curare affect signaling at the neuromuscular junction? Curare blocks the endplate potential because it is a competitive inhibitor of acetylcholine (ACh), the transmitter released at the presynaptic terminal. ... Curare affectsthe stimulus (the EPSP)which normally leads to the initiation of...
This means they block the chemicals histamine and acetylcholine in the body, respectively. These actions aren’t thought to help the medications work to treat mental health conditions. But they are driving factors for many common side effects, like dry mouth and constipation....
Neuroimmunology is one of the fastest-growing fields in the life sciences, and for good reason; it fills the gap between two principal systems of the organism, the nervous system and the immune system. Although both systems affect each other through bidi
Extrinsic nerves are based in the unconscious part of the brain and in the spinal cord, and they need the help of the chemicals acetylcholine and adrenaline. Acetylcholine works with hormones to encourage the stomach and pancreas to make more digestive juices. But its main function involves the...
