stress and cognition Flashcards
do you have top-down control or bottom-up control when you’re stressed?
bottom up
what is it meant by top-down processes
something you control, starts with your brain and works its way down to 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
show 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
does stress effect your brain functions
yes
what part of the brain is in charge when you’re not stressed
the prefrontal cortex
when we are stressed, what part of the brain is more dominant
the amygdala
what system that connects the brain to body uses our nerves to do so
the nervous system
how does the nervous system connect our brain to our body
sends signals through our nerves
what system connects brain to body using hormones
the endocrine system
how does the endocrine system connect our brain to our body
sends hormones to send messages
how does our immune system connect our brain to our body
uses lymphocytes and inflammation
what system uses lymphocytes and inflammation to connect brain to body
the immune system
what part of the brain controls the two main stress response systems
the hypothalamus
what are the two main stress responses the hypothalamus controls in the stress response system
the sympathetic adrenal medullary (Adrenalin) and the hypothalamic pituitary adrenal axis (cortisol) i.e SAM & HPA
what do SAM and HPA stand for
Sympathetic adrenal medullary and hypothalamic pituitary adrenal axis
what does the sympathetic adrenal medullary do
controls the production of adrenalin in the stress response system
what does the hypothalamic pituitary adrenal axis do
controls the production of cortisol in the stress response system
what regulates 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 hormone triggers the immune system when we’re stressed
cortisol
what happens when the two stress response systems are over worked
we become ill
what causes us to have ill health when we have chronic stress
when the two stress response systems are over worked
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 minutes
what parts of the body can/does cortisol effect
all parts, e.g skin, kidney processes, literally everything
what stress hormone can effect all parts of our body
cortisol
what are the three main parts of the neuroendocrine system (hypothalamic pituitary adrenal axis)
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 (hypothalamic pituitary adrenal axis)
in the neuroendocrine system (hypothalamic pituitary adrenal axis), what is the first step
the hypothalamus releases the cortisol releasing hormone (CRH)
in the neuroendocrine system (hypothalamic pituitary adrenal axis), where is the cortisol releasing hormone sent from and sent to and how is it sent
sent from the hypothalamus to the pituitary gland through the blood stream
in the neuroendocrine system (hypothalamic pituitary adrenal axis), what hormone does the pituitary gland release and where does it get released to and how
the pituitary gland releases the Adrenocorticotropic hormone (ACHT) to the adrenal gland through the blood stream
in the neuroendocrine system (hypothalamic pituitary adrenal axis), what is sent to the adrenal gland, what gland was it sent from, how was it sent and what does the adrenal gland create and release
the adrenal gland detects the Adrenocorticotropic hormone (ACHT) that was sent from the pituitary gland through the blood stress, it then creates and releases cortisol into the blood stream
explain the neuroendocrine system (hypothalamic pituitary adrenal axis)
hypothalamus –> releases CRH (cortisol releasing hormone) into blood supply –> the pituitary gland receives the hormone and produces/releases Adrenocorticotropic hormone (ACHT) –> Adrenocorticotropic hormone (ACHT) is sent in the blood supply –> the adrenal gland detects the Adrenocorticotropic hormone (ACHT) –> adrenal gland creates and releases cortisol into the blood
how can cortisol be measured
through our saliva, hair, urine, blood etc.
what are the side effects of excessive cortisol (chronic stress)
depression, heart attacks, cancer, diabetes, high blood pressure etc.
what is the Elisa Assay system
the process of measuring cortisol through saliva
