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.
Unlike a hybrid, they have no gas engine to fall back on and are thus limited to their battery pack's driving range. Models such as the Ford Focus Electric and Nissan Leaf have driving ranges from about 75 to 107 miles; the much more expensive Tesla Model S can go nearly 300 miles.
