Broadly speaking, endocrine disorders may be subdivided into three groups: 1  Endocrine gland hyposecretion (leading to hormone deficiency) 2  Endocrine gland hypersecretion (leading to hormone excess)  Tumours (benign or malignant) of endocrine glands.

Under ideal driving conditions, Musk claimed, the new Roadster can go as far as 400 miles without stopping to recharge. Naturally, a lot of Tesla watchers are probably wondering when the Model S (which is significantly more affordable but still out of reach of most consumers) will benefit from this technology.
The Tesla Roadster can go a lot faster than previous electric cars, but perhaps more importantly, it can go a lot farther. The Roadster's estimated range is 250 miles on a single charge, at least 100 miles more than General Motors' EV1, which could go almost 150 miles under optimal conditions. Most of the hype surrounding the Roadster is about its status as an electric vehicle.
