Document Summary
Lab partners: morgan simpson, sarah cottrill, courtney webb. Ethyl alcohol is a known inhibitor of certain neurotransmitters, hormones, and proteins. Norepinephrine, plays a big role in the regulation of the organism"s heart rate. Norepinephrine signals the cell to produce large amounts of calcium ions which allows the signal between the nodes of the heart to quicken and speed up the heart rate. In a study done by arthur wilde it was discovered that there is a large amount of evidence for a [norepinephrine] induced stimulation of the na+-k+ pump in cardiac tissue (wilde et al. Norepinephrine plays a key role in the function of the cation ion pump which produces a membrane potential that drives the electrochemical signal that affects heart rate. Alcohol reduced the nmda-induced release of several neurotransmitters, including dopamine, norepinephrine, and acetylcholine (gonzales et al. Thus, by reducing the norepinephrine output alcohol can effectively reduce heart rate.
