Endocrine Flashcards
(47 cards)
Gland that helps w water retention
posterior pituitary gland
(vasopression)
Gland - labor contractions
Posterior pituitary
(Oxytocin)
Helps immune system
Thymus
(thymosin)
master gland
hypothalmus
secretes hormones that regulate other hormones
anterior pituitary
Sympathetic nervous sys stimulates
adrenal glands
(epinephrine)
blood sugar regulation
Pancreas
(insulin + glucagon)
Glands are triggered by
Hormonal, humoral, neural
Hormonal
glands are stimulated by hormones secreted by other glands
Ex: hypothalamus triggers the pituitary
Humoral
levels of nutrients or iron in the blood trigger glands to secrete
EX: Ca2+ levels Inc or dec from expected level trigger parathyroid
Neural
nerve impulse causes gland to secrete
EX: sympathetic NS triggers adrenal gland when stressed
Two types of hormones
steroidal (lipid soluble)
non steroidal (water soluble)
Steroidal
Can pass through the target cells cell membrane
altering the action of the cell
(turning it on or off)
Non steroidal
Amino acid based
NOT able to pass thru cell membranes
Bind @ receptor on outside
Triggers steps
How do glands help w homeostasis
Regulate body + processes
Inc or dec
feedback loop
most in pairs so to keep balance
Wake + sleep cycle
pineal gland
melatonin
Anterior pituitary gland
Produces hormones that regulate other hormones
GH, TSH, ACTH, FSH, LH + prolactin
Posterior pituitary gland
recieves and releases hormones
“storage area”
Oxytocin + vassopressions+ ADH
hypothalamus
master - regulation of all glands
maintain homeostasis
control brainstem + spinal cord
CRH, GHRH, PRH, GHIH and TSH
thyroid
secretes hormones to regulate BP, growth + metabolic rate
T3 + T4
parathyroid
controls balance of calcium in blood
PTH
adrenal glands
role in how our body responds to stress
Inner layer: medulla -Epinephrine + epinephrine
outer layer: cortex
glucocortoid
pancreas
blood sugar regulation
uses both exocrine + endocrine
glucagon + insulin
Ovaries
estrogen + progesterone
