17
Q

what part of the brain controls the two main stress response systems

A

the hypothalamus

18
Q

what are the two main stress responses the hypothalamus controls in the stress response system

A

the sympathetic adrenal medullary (Adrenalin) and the hypothalamic pituitary adrenal axis (cortisol) i.e SAM & HPA

19
Q

what do SAM and HPA stand for

A

Sympathetic adrenal medullary and hypothalamic pituitary adrenal axis

20
Q

what does the sympathetic adrenal medullary do

A

controls the production of adrenalin in the stress response system

21
Q

what does the hypothalamic pituitary adrenal axis do

A

controls the production of cortisol in the stress response system

22
Q

what regulates adrenalin in the stress response system

A

the sympathetic adrenal medullary

23
Q

what regulates cortisol in the stress response system

A

the hypothalamic pituitary adrenal axis

24
Q

what does the hypothalamus control

A

appetite, sleep, stress, growth hormones, sexual functions etc.

25
Q

what hormone triggers the immune system when we’re stressed

A

cortisol

26
Q

what happens when the two stress response systems are over worked

A

we become ill

27
Q

what causes us to have ill health when we have chronic stress

A

when the two stress response systems are over worked

28
Q

what hormone/neurotransmitter is fast acting when we endure stress

A

adrenaline

29
Q

what hormone is slow acting when we endure stress

A

cortisol

30
Q

how long does it take for cortisol to kick in when we’re stressed

A

15-20 minutes

31
Q

what parts of the body can/does cortisol effect

A

all parts, e.g skin, kidney processes, literally everything

32
Q

what stress hormone can effect all parts of our body

A

cortisol

33
Q

what are the three main parts of the neuroendocrine system (hypothalamic pituitary adrenal axis)

A

the hypothalamus gland, the adrenal gland and the pituitary gland

34
Q

what stress system are the hypothalamus gland, the adrenal gland and the pituitary gland a part of

A

neuroendocrine system (hypothalamic pituitary adrenal axis)

35
Q

in the neuroendocrine system (hypothalamic pituitary adrenal axis), what is the first step

A

the hypothalamus releases the cortisol releasing hormone (CRH)

36
Q

in the neuroendocrine system (hypothalamic pituitary adrenal axis), where is the cortisol releasing hormone sent from and sent to and how is it sent

A

sent from the hypothalamus to the pituitary gland through the blood stream

37
Q

in the neuroendocrine system (hypothalamic pituitary adrenal axis), what hormone does the pituitary gland release and where does it get released to and how

A

the pituitary gland releases the Adrenocorticotropic hormone (ACHT) to the adrenal gland through the blood stream

38
Q

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

A

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

39
Q

explain the neuroendocrine system (hypothalamic pituitary adrenal axis)

A

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

40
Q

how can cortisol be measured

A

through our saliva, hair, urine, blood etc.

41
Q

what are the side effects of excessive cortisol (chronic stress)

A

depression, heart attacks, cancer, diabetes, high blood pressure etc.

42
Q

what is the Elisa Assay system

A

the process of measuring cortisol through saliva
