Question

Name the emergency hormone? From where it is released? How does it protect our body from stress?

Answer 1

The emergency hormone raises metabolic rate and induces dilation of heart and brain blood vessels. It also increases fat metabolism and hence more energy is synthesized.

Complete answer:
Adrenaline hormone is known as the Emergency Hormone or Epinephrine because it initiates a rapid reaction that helps the person think rapidly and respond to stress. It raises the rate of metabolism, dilating the blood vessels going into the heart and brain.

Adrenaline hormone is released from the adrenal gland medulla region. Its secretion falls under sympathetic nervous system regulation. Two hormones are released, called epinephrine and norepinephrine. Commonly these two compounds are called catecholamines. Epinephrine is released during any form of stress or emergencies and is thus referred to as an emergency hormone and the adrenal gland is called the emergency gland. During the fear, it also prepares the body to fight or flight hence also called 3F.

In a stressful environment, adrenaline escapes rapidly into the blood and sends impulses to the organs to generate a particular reaction. This secretion starts to respond to a specific target organ like the lungs, heart, blood pressure, metabolism, and other activities. As adrenaline is released, the heart begins to beat rapidly thus providing the muscles with a rush of oxygen. The rush to supply muscles with oxygen has an effect on the lungs that results in quick, rapid contractions of the diaphragm and rib muscles. Blood flows down into the skin and digestive tract. Because of the contraction. The arteries connected with those muscles tend to increase blood flow to the skeletal system.

All these events occur during stressful conditions, so adrenaline is known as an emergency hormone.

Note: Adrenaline is indeed a very fast-acting hormone that stimulates our body for immediate action, also known as the fight or flight reflex. It accelerates our respiration and heart rate and diverts extra blood to the muscles.
