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). Other forms of thyrotoxicosis include thyrotoxicosis factitia and those associated with different forms of thyroiditis.
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).
Wolves, coyotes and mountain lions will give chase to deer, who rely on speed and agility to survive. The white-tailed deer can sprint as fast as 35 miles per hour; however, he can't maintain the speed for long periods of time. As a bonus, he's a great jumper, able to clear a 7-foot height from a standing position and up to 10 feet when running. He can bound well too, covering as much as 30 feet in a single leap.
