Endocrine Flashcards
what are the areas of the adrenal gland
- capsule
- zona glomerulosa
- zona fasciculata
- zona reticularis
- medulla
what is produced in the medullary of the adrenal gland
epinephrine and norepinephrin
what is produced in the zona glomerulosa
aldosterone and corticosterone
what is produced in the zona fasciculata
cortisol and cortisone
what is produced in the zona reticularis
estrogens and testosterone
what does cortisol do
- regulates metabolism
- metal wakefulness
- response to danger
- cognition
- healing
- blood sugar
- fluid balance
- BP
What does adrenalin do?
- increase breathing
- blood circulation
- carbohydrate metabolism
- preps muscles for exertion
where is adrenalin produced
exclusively in the meulla of the adrenal gland
what is adrenalin synthesised from
noradrenalin
which adrenergic receptors does adrenalin activate
both alpha and beta
4 effects of adrenalin:
- increase heartrate
- relax breathing tubes
- increase BP
- increase blood sugar
noradrenalin:
- released by adrenal medulla
- neurotransmitter
- raise BP
where is noradrenalin produced
medulla of the adrenal gland and
sympathetic nervous system
what is noradrenalin synthesised from
dopamine
which adrenic receptors does noradrenalin activate
only apha receptors
what is the main effect of noradrenalin
increase BP by vasoconstriction
what are the effects of ACTH
- produce aldosterone
- cortisol
- sex hormones
- epinephrin and
- norepinephrin
functions of the liver (that we are concerned with)
- detox
- storage
- blood sugar
- produce bile
- make proteins
- immune system
- metabolism
what is the role of the pineal gland
produce melatonin
what does the pituitary glnd produce
- ADH
- oxytocin
- TSH
- ACTH
- prolactin
- growth hormone
- gonadotropic hormones
