Question

Name the hormonal secretion which takes place under the emergency conditions of stress, anger and fear.

Answer 1

Hint: Conditions where there is a lot of stress or fear or anger the body needs to respond quickly and needs to make an intake of oxygen more than a hormone is released. The hormone helps in increasing the strength of the human body.

Complete answer:
Whenever our body faces stressful conditions our brain responds to it by producing hormones called adrenaline. Adrenaline is also called epinephrine. The hormone responds only in the emergency situations or flight and fight conditions.

Additional Information: Adrenaline is produced in the medulla region of the central nervous system. This hormone triggers the fight and flight response in the body. In such conditions the air passage dilates in order to provide more oxygen to the lungs. The blood vessels contract and blood is made to flow towards lungs and heart more. It also nullifies the pain felt to our body and increases our senses in such conditions. Excessive amounts of adrenaline in the body when there is no stressful condition can lead to harmful effects in the health. If the amount of adrenaline released is not used then the person might feel dizziness, restlessness and irritability. These symptoms appear as the extra amount of energy is not used by the body. Excessive amounts of adrenaline present in the body can be very harmful and can cause serious problems in the heart, nervous feeling and insomnia.

Note: Adrenaline is released from the medulla region of the adrenal gland. It is only released in the stressful conditions of the body like fear, anger etc. The hormone is directly released into the bloodstream for fight and flight response.
