BIOMOLECULES AND ENZYMES

Detailed explanation-1: -The adrenal medulla, the inner part of an adrenal gland, controls hormones that initiate the flight or fight response. The main hormones secreted by the adrenal medulla include epinephrine (adrenaline) and norepinephrine (noradrenaline), which have similar functions.

Detailed explanation-2: -Adrenaline is produced in the adrenal glands, which release adrenaline into the body during times of stress or danger. It prepares your body to face a stressful “fight or flight” situation.

Detailed explanation-3: -After the amygdala sends a distress signal, the hypothalamus activates the sympathetic nervous system by sending signals through the autonomic nerves to the adrenal glands. These glands respond by pumping the hormone epinephrine (also known as adrenaline) into the bloodstream.

Detailed explanation-4: -Adrenaline is released by the adrenal glands in the body. Hypothalamus sends the signal of releasing adrenaline whenever there is a situation of flight, fright, or fight. Adrenaline accelerates the rate of heart along with the flow of blood in the vessels and helps in tackling emergency situations.
