adrenaline hormone Mukabala baccha karo ?
Answers
Answer:
Adrenaline
Adrenaline is a hormone released from the adrenal glands and its major action, together with noradrenaline, is to prepare the body for 'fight or flight'.
Answer:
When the brain perceives danger, the amygdala triggers the hypothalamus to activate the autonomic nervous system.
Signals from the autonomic nervous system stimulate the adrenal gland to start pumping epinephrine into the bloodstream. People often refer to this surge of epinephrine as an adrenaline rush or the fight or flight response.
Epinephrine affects the heart, lungs, muscles, and blood vessels. Its release into the bloodstream brings about several physiological changes, such as:
increased heart rate and blood flow
faster breathing
raised blood sugar levels
increased strength and physical performance
Non epinephrine
The adrenal medulla produces norepinephrine in response to low blood pressure and stress. Norepinephrine promotes vasoconstriction, which is a narrowing of the blood vessels, and this increases blood pressure.
Like epinephrine, norepinephrine also increases the heart rate and blood sugar levels.
