Question

Triple ‘F’ or gland for flight,fight, and fright/ life saving/ emergency gland is-
a. Thyroid
b. Thymus
c. Pituitary
d. Adrenal

Answer 1

As soon as the hypothalamus tells the sympathetic nervous system to kick into action, the overall effect on our body is that the body speeds up, tenses up and becomes generally very alert. For example If there's a burglar at the door, you're going to have to take action and fast.

Complete answer:
A. Thyroid gland is generally situated between the trachea and the larynx in the neck & secretes thyroxine hormone which tends to increase the oxygen consumption by metabolically active tissues.

B. Thymus gland is normally associated with development of the immune system & present on the dorsal side of the heart.

C. Pituitary gland is the master gland which regulates the activity of other endocrine glands and secretes many hormones like growth hormone, follicle stimulating hormone, thyroid stimulating hormone etc.

D. Adrenal gland is present on the upper side of the kidneys and has two parts, adrenal cortex which secrete the glucocorticoids, mineralocorticoids and sexcorticoids and adrenal medulla which secretes adrenaline and nor-adrenaline hormone. Adrenaline is also widely known as an emergency hormone. This hormone is generally associated with the maintenance of homeostasis in the body and is secreted in the response to any kind of stress or emergency in the body. It is also known as the hormone of fight or flight.

Hence, the correct answer is option (D).

Note: The sympathetic nervous system present sends out impulses to glands and to the smooth muscles and tells the adrenal medulla to release epinephrine and norepinephrine into our bloodstream.
