Pineal gland
Hypothalamus
Pituitary gland
Thyroid gland
Thymus gland
Pancreas
Adrenal glands
Testes
(male)
Ovaries
(female)
chemical fluids produced by organisms
influencing growth, development, sex, etc.
carried throughout the bloodstream
Pineal


Hypothalamus


Pituitary


Thyroid


Thymus


Adrenals


Pancreas


Ovaries

Testes

Glands
-melatonin


-growth hormone


-oxytocin "love hormone"


-thyroid hormone


-humoral hormones


-adrenalin, cortisol


-insulin


-estrogen, progesterone

-testosterone

Hormone(s)
Function
sleep time


body composition


labour, social behaviour


metabolism


immune system


use of energy


blood sugar level


promotes ♂/♀ development
Adrenalin
Endocrine System
released by adrenal gland
adrenal gland: 2 types
adrenal cortex (outer)
adrenal medulla (inner)
stress: a biological and psychological response experienced on encountering a threat
Rosenthal, 1987
Lmao so what's fight or flight?????
- evidence that higher melatonin levels contribute to SAD

- found that bright lights supress melatonin production

- successfully treated patient
with seasonal depression through
phototherapy
Walter Cannon (1871-1945)
if animals were scared or disturbed, peristaltic waves in the stomach sometimes ceased abruptly
the sympathetic division of its autonomic nervous system combines with the hormone adrenaline to mobilize the animal for an emergency response of “flight or fight.”
- secreted by Pineal gland in the brain

- released in a cycle dictated by light

- signals body when it is time to sleep

- correlates to circadian rhythm
Melatonin
, NOT melanin
Cannon
little to no ethical considerations
process not outlined
assumed inc. adrenaline = flight/fight
adrenaline can inc by standing up
Rosenthal, 1987
Ethical, or nah?
patient willing to be treated
phototherapy somewhat controversial
endocrine system contains the glands that secrete hormones
Fight or flight: our automatic reaction to stressful/potentially dangerous situations
HORMONES? WHAT ARE THOSE???!!!
