Stress And Cognition Flashcards
Do you have top-down control or bottom-up control when stressed?
Bottom up
What is it meant by top-down processes
Something you control, starts with your brain and works its way down the body
What is it meant by bottom-up processes
A process that is controlled by a stimuli and you react to it, you have no control
What is acute stress
Short term stress
What is the phrase to describe short-term stress
Acute stress
What is chronic stress
Prolonged stress
What is the phrase to describe prolonged stress
Chronic stress
What part of the brain is in charge when you’re not stressed
Prefrontal cortex
What part of the brain is in control when we are stressed
The amygdala
What system uses nerves to connect brain to body
The nervous system
How does the nervous system connect our brain to body
Through our nerves
What system connects brain to body using hormones
Endocrine system
How does the endocrine system connect brain to body
Hormones
How does our immune system connect our brain to our body
Lymphocytes and inflammation
What system uses lymphocytes and inflammation to connect brain to body
Immune system
What part of the brain controls the 2 main stress response systems
The hypothalamus
What are the 2 main stress responses the hypothalamus controls in the stress response system
The sympathetic adrenal medullary and the hypothalamic pituitary adrenal axis ( SAM & HPA )
What do SAM and HPA stand for
Sympathetic Adrenal Medullary & Hypothalamic Pituitary Adrenal Axis
What does the sympathetic adrenal medullary do
Controls the production of Adrenalin
What does the hypothalamic pituitary adrenal axis do
Controls the production of cortisol in the stress response system
What controls Adrenalin in the stress response system
The sympathetic adrenal medullary
What regulates cortisol in the stress response system
The hypothalamic pituitary adrenal axis
What does the hypothalamus control
Appetite, sleep, stress, growth hormones, sexual functions etc.
What hormones triggers the immune system when we’re stressed
Cortisol
What happens when the 2 stress response systems are over worked
Illness
What causes us to have ill health when we have chronic stress
When the 2 stress response systems are overworked
What hormone/neurotransmitter is fast acting when we endure stress
Adrenaline
What hormone is slow acting when we endure stress
Cortisol
How long does it take for cortisol to kick in when we’re stressed
15-20 mins
What part of the body does cortisol effect
Everything
What stress hormone can effect all parts of our body
Cortisol
What are the 3 main parts of the neuroendocrine system
The hypothalamus gland, the adrenal gland and the pituitary gland
What stress system are the hypothalamus gland, the adrenal gland and the pituitary gland a part of
Neuroendocrine system
What is the first step of the neuroendocrine system
The hypothalamus releases the cortisol releasing hormone
Int he neuroendocrine system, where is the cortisol releasing hormone sent from and sent to and how
Sent from the hypothalamus, through the blood and to the pituitary gland
Int he neuroendocrine system, what hormone does the pituitary gland release and where does it get released to and how
ACHT through the blood and to the adrenal gland
In the neuroendocrine system, what is sent to the adrenal gland, where from, how and what does the adrenal gland produce
ACHT sent from the pituitary gland through blood, Adrenal glad produces adrenalin
Explain the neuroendocrine system
Hypothalamus releases cortisol releasing hormone through blood to pituitary gland, ACHT is then sent from pituitary gland through the blood to the adrenal gland who then releases cortisol into the blood
How can cortisol be measured
Saliva, blood, hair, wee etc.
What are the side effects of excessive cortisol
Depression, heart attack, cancer, diabetes, high blood pressure
What is the Elisa Assay System
The process of measuring cortisol through saliva
Which stress response system is immediate rapid response to stress
The sympathetic adrenal- medullary (Sam)
Does stress lead to increase reliance on automatic processing
Yes
Does stress influence risk taking
Yes
Does cortisol increase or decrease risk taking in men
Increase
Does cortisol increase or decrease risk taking in women
Decrease
What response does cortisol trigger in the immune system
Inflammation
What part of the brain do we lose regulation in when stressed
The pre-frontal cortex
Can chronic tress cause psychiatric disorders
Yes
