the Researchers chose to use Rattus norvegicus (Sprague Dawley Rats) since rats are considered one of the most commonly used animals in the laboratory. Rat strain is created through breeding to produce rats that are similar to each other and can therefore be used in research. Wistar‚ Fisher and Sprague Dawley‚ and their hundreds of internal divisions‚ are examples of rat strains. Most laboratory rat strains descend from a colony of rats established at the Wistar institute in 1906. The Sprague Dawley

1. Which rat‚ A‚ B or C has no thyroid gland? Rat A (1 pts) 2. Justify your answer. (what data convinced you of your answer) (1 pts) T3 and T4 regulate the metabolism‚ so when more is available it increases the baseline metabolic rate. TSH causes the release of T3 and T4‚ so if the rat is injected with TSH‚ in theory we would suggest that the levels of T3 and T4 are also higher than the baseline metabolic rate. 3. In a further experiment‚ all 3 rats were given a drug that inhibits the production

Each rat was kept in a single housed area with controlled temperature and humidity‚ lights would turn on and off at the same time. Each rat was prepared by an 11-mm electrode within the medial forebrain bundle. Each rat began eating regular lab chow and it was slowly changed to lieber DeCarli liquid diet‚ experiments 1 and 2 had 36% of calories taken from alcohol‚ while experiment 3 had 48%taken from alcohol. Each control rat was paired with an alcohol rat based off of weight‚ and
