Question

Which hormone is known as the emergency hormone in our body?
(a)Insulin
(b)Adrenaline hormones
(c)Androgen
(d)Oxytocin and vasopressin

Answer 1

Hint: These hormones initiate the flight or fight response that increases blood flow to the muscles, output of the heart, blood sugar level, and pupil dilation. Epinephrine and norepinephrine are the main hormones secreted by the adrenal medulla which have similar functions.

Complete step-by-step answer:
Adrenaline hormone (Epinephrine) is known as an emergency hormone and secreted during the time of stress or emergency. Adrenaline is secreted in the blood during an emergency. The secretion begins reacting to a target organ such as the lungs, heart, blood pressure, metabolism, and such activities. Upon the release of adrenaline, the heartbeat increases thereby supplying a rush of oxygen to the muscles. This has an impact on the lungs which leads to fast rapid contractions of the diaphragm and the rib muscles. The blood flow to the skin and digestive system reduces. Also dilates the pupil, dilates the blood vessels, and increases the metabolic rate.

Additional Information: Insulin - produced in the pancreas by the islets of Langerhans, is a peptide hormone. The metabolism of carbohydrates, fats, and protein is regulated by insulin by promoting the absorption of glucose from the blood into the liver, fat, and skeletal muscle cells. A form of diabetes is caused by insulin.
Androgen- regulates the development and maintenance of male characteristics is a synthetic steroid hormone. The principal androgens are testosterone and androstenedione and are present in both males and females. Androgens are crucial for male sexual characteristics in men such as facial and body hair growth, voice change, and reproductive function. It also affects bone and muscle development and metabolism.
Arginine Vasopressin (AVP) and oxytocin (OXT) - peptide hormones AVP's physiological roles include regulating blood pressure. Nearly all vertebrates have an oxytocin-like nonapeptide hormone that helps in reproductive functions and a vasopressin-like nonapeptide hormone supporting water regulation.
So, the correct answer is 'Adrenaline hormones'.

Note: Any member of a class of signaling molecules to stimulate specific cells or tissues into action, produced by glands in multicellular organisms that are transported by the circulatory system to target distant organs is known as a hormone.
