Thyrotoxicosis is a clinical condition resulting from the action of excess thyroid hormone on tissues. The term hyperthyroidism is usually reserved for thyrotoxicosis caused by excessive production of thyroid hormone (Boxes 4 and 5).

How Fast Can A Reindeer Run? The reindeer (Rangifer tarandus), also known as the caribou in North America, is a deer from the Arctic and Subarctic, including both resident and migratory populations. While overall widespread and numerous, some of its subspecies are rare and one (or two, depending on taxonomy) has already gone extinct. Normally travelling about 19â55 km (12â34 mi) a day while migrating, the caribou can run at speeds of 60â80 km/h (37â50 mph).
In skating, one skate pushes and the other skate glides--there is very little friction to slow you down. Speed skater Hiroyasu Shimizu of Japan can travel 500 meters in just 35.39 seconds, an average speed of 14.13 meters per second or 31.6 miles per hour.he friction between the blade and the ice is minimized because the surface of the ice is so slippery, and because only a small portion of the skate's blade is actually in contact. The Mechanics of Skating NHL players can reach speeds in excess of 20 miles (32 km) per hour on the ice.
