Solution
The thyroid gland is also called as nature gland because it secretes thyroxin hormone which is mainly responsible for the normal behaviour of human beings. In adequate supply of hormones human behaviour remains normal. In case of excess supply of hormones in the blood there are increased metabolic activities, raised nervous excitability and increased physical activity accompanied by fatigue and loss of weight.
