What specific messengers are involved in the fight or flight response?

Fight or Flight Chemical Messengers

What are the physiological changes involved in fight or flight?

The fight or flight response is an automatic physiological reaction to an event that is perceived as stressful or frightening. The perception of threat activates the sympathetic nervous system and triggers an acute stress response that prepares the body to fight or flee.

What happens to the production of adrenaline in response to stress quizlet?

Adrenaline is mainly released in response to stressful events to prepare the body for the ‘fight or flight’ response. These events lead to the activation of nerves connected to the adrenal glands, which trigger the secretion of adrenaline and thus increase the levels of adrenaline in the blood.

Which gland is involved in the fight or flight response quizlet?

A hormone secreted from the adrenal glands. Its role is to reinforce the actions of the sympathetic nervous system, preparing the body for action and increasing the supply of blood and oxygen to the skeletal muscles and to the brain.

Which two hormones mediate the stress response?

When presented with a stressful situation, the body responds by calling for the release of hormones that provide a burst of energy. The hormones epinephrine (also known as adrenaline) and norepinephrine (also known as noradrenaline) are released by the adrenal medulla.

Why do I freeze instead of fight or flight?
