What is the role of the adrenal medulla in the flight and fight response?

Answer 1

adrenal medulla is very important for human body to face conditions of fight,flight,fright.it releases mainly two important hormones such as adrenaline,and noradrenaline hormones.

ADRENALINE AND NORADRENALINE;these are post ganglionic neurotransmitter.

functions';noradrenaline regulate BP by general vasoconstriction of all blood vessels except coronary blood vessels.while adrenaline causes vasoconstriction of blood vessels supplied to skin.it dilates and causes vasodilation of blood vessels supplied to heart and brain and skeletal muscle.

it also causes bronchi oles to dilate ,more intake of oxygen and dilation of pupil also occurs.

thus it prepares body to such situations and saves human in such conditions.again after sometime normal situation occurs and again viceversa for above conditions occurs.

Answer 2

Lets see, the pupils dilate, the heart rate increases as adrenalin is put into the blood stream, and the muscles tense up. The arteries narrow as blood pressure increases, blood is channeled more to the skeletal muscles than any other part of the body as the body prepares for combat, or flight. I think that is basically it.

Answer 3

The adrenal medulla secretes adrenaline and noradrenaline in response to stress, activating the fight-or-flight response. These hormones increase heart rate, dilate airways, and mobilize energy reserves to prepare the body for action.

Answer 4

a flight or fight basically means that when your adrenalin kicks in your first two reactions are either to run away or fight.

Answer 5

The hormones of the adrenal medulla are secreted to create a sympathetic nervous system response and to maintain that response for short term stressors.
