Correct option is A
The correct answer is (a) Adrenaline.
· Adrenaline, also known as epinephrine, is a hormone released by the adrenal glands during emergency or stressful situations.
· This hormone prepares the body for the "fight-or-flight" response, which enables an individual to react quickly in a dangerous or challenging situation.
· Adrenaline increases heart rate, boosts blood flow to muscles, dilates airways, and raises blood sugar levels to provide more energy.
· It plays a crucial role in survival, giving the body the extra strength and alertness required during emergencies.
· This rapid response helps individuals either face the threat or escape from it.
Additional Information:
· Norepinephrine: This hormone, also known as noradrenaline, is similar to adrenaline and also plays a role in the body's fight-or-flight response. However, it is more involved in the maintenance of blood pressure and alertness rather than immediate physical reactions like adrenaline.
· Corticotropin: Also known as Adrenocorticotropic Hormone (ACTH), this hormone is produced by the pituitary gland and stimulates the adrenal glands to release cortisol.
· Cortisol: This hormone is often called the "stress hormone" because it helps regulate metabolism, reduce inflammation, and assist in managing stress. Cortisol is released in response to long-term stress and helps the body maintain steady energy levels
