Flight or Fight Response Process Flashcards
The steps the body goes through the combat dangerous situations
What is the first stage of the fight or flight response
Person enters dangerous situation
What is the second stage of the fight or flight response
Amygdala is activated, it sends a distress signal to the hypothalamus.
What system is the amygdala apart of and what does the system do
Limbic System, a group of structures in the brain that regulates emotions, memory, motivations and behaviour
What is the third stage response
The hypothalamus activates the SAM Pathway and pituitary gland( which releases acth)
What is the SAM Pathway
A pathway running to the adrenal medulla and sympathetic nervous system
What is the fifth stage
The Adrenal medulla secretes hormones: Adrenaline + Noradrenaline into the bloodstream
Pituitary secretes: Cortisol ( from adrenal cortex)
What is the final stage
Adrenaline causes a number of physiological changes to prepare the body for fight or flight
Give 4 examples of physiological changes the body goes through during fight or flight and why
Digestion slows down: So body can focus on threat, puts all of energy into getting away from danger
Palms sweat: Adrenaline activates sweat glands
Pupils dilate: So the eyes can take in as much light as possible/ so person can see more
Heart rate increases: deliver more blood to areas of your body that need more oxygen or other responses to help your get out of danger
What system does the adrenal gland belong to
Endocrine System
