Question

The hormone concerned with facing dangers is .......... (thyroxine/cortisone/adrenalin).

Answer 1

• Thyroxine is secreted from thyroid gland. Thyroxine controls the metabolic rate of body and increases the oxidation of glucose in tissues.
  
• Cortisone is a glucocorticoid secreted from adrenal cortex. It regulates carbohydrate metabolism and formation and storage of glycogen. Also, it promotes sodium and water reabsorption from the renal tubules.
  
• Adrenaline is secreted from the adrenal cortex and is known as emergency hormone. It is associated with regulating the potential for conditions needed for fight or flight. When the body is under stress, homeostasis is disturbed and this immediate response is described as preparing the body for 'fight or flight'. It increases alertness, pupillary dilation, raising of hairs or piloerection etc.

Hence, the hormone concerned with facing dangers is adrenaline.

So, the correct answer is 'Adrenaline'.
