- Front
- Back
|
Endocrine Glands
|
Release hormones
No ducts, into bloodstream increase or decrease target activity |
|
|
Negative feedback
|
Most are negative
Stimulus--Response--reduces a level of stimulus, back to homeostasis |
|
|
Positive feedback
|
Produce--continue to produce
|
|
|
Hypothalamus
|
-Produces regulatory hormones that stimulate or inhibit Ant pituitary
-Produces ADH, oxytocin and store them in Post Pituitary -Overseer of ANS -Stimulates hormone secretion of Adrenal medulla |
|
|
ADH (antidiuretic hormone)
|
regulates water reabsorption
|
|
|
Oxytocin
|
Regulates milk secretion, uterine contractions, male smooth muscle
|
|
|
Anterior Pituitary
|
TSH, prolactin, ACTH, growth hormone, FSH/LH, MSH
|
|
|
Posterior Pituitary
|
Stores ADH and oxytocin from hypothalamus
|
|
|
TSH (thyroid-stimulating hormone)
|
Acts on thyroid gland, tells it to release its hormones
|
|
|
Prolactin
|
-acts on mammary glands and testes
-milk production |
|
|
ACTH (adrenocorticotropic hormone)
|
Acts on adrenal cortex
corticotropic cells |
|
|
Growth Hormone
|
Acts on all body tissues, especially bone
somatotropic cells |
|
|
FSH
(follice stimulating hormone) |
gonadotropic cells
produce sex cells |
|
|
LH
(lutenizing hormone) |
gonadotropic cells
increase production of gonad hormones |
|
|
MSH
(melanocyte-stimulating hormone) |
melanocytes
increase production of melanin |
|
|
Pituitary Dwarfism
|
Inadequate growth hormone production
|
|
|
Pituitary Gigantism
|
Oversecretion of growth hormone in childhood
|
|
|
Acromegaly
|
Excessive growth hormone production in adults
|
|
|
Thyroid gland- pituitary gland negative feedback loop
|
1) low body temp- hypothalamus releases TRH
2) Ant pituitary release TSH 3) TSH stimulates thyroid to release TH 4) TH increases metabolic activity, increase body temp 5) increased body temp detected by hypothalamus inhibits secretion of TRH |
|
|
Hyperthyroidism
|
excessive production of TH
weight loss, hyperactivity, heat intolerance |
|
|
Graves Disease
|
Hyperthyroidism and bulging eyeballs
|
|
|
Hypothyroidism
|
decreased production of TH
|
|
|
Goiter
|
enlargement of thyroid
insufficient iodine |
|
|
Calcitonin
|
release by thyroid gland
Calcium from blood to bones |
|
|
Parathyroid Hormone
|
Released by parathyroid glands
Calcium out of bones into blood stream |
|
|
Addison Disease
|
adrenal insufficiency
|
|
|
Adrenal Cortex
|
Produce/release a group of corticoseroids
-electroytes , glucose, sex cells |
|
|
Adrenal Medulla
|
Epinephrin(adrenaline), Norepinephrin
-like sympathetic, fight/flight -last longer than nervous system effects |
|
|
Pancreas
|
Glucose regulation
-Insulin, Glucagon |
|
|
Insulin
|
Glucose out of blood into cells
|
|
|
Glucagon
|
Makes cells release glucose, increase glucose blood levels
|
|
|
Diabetes
|
INadequate uptake of glucose from the blood
|
|
|
Type 1 Diabetes
|
insulin dependant
- absent or diminished production and release of insulin |
|
|
Type 2 Diabetes
|
Insulin independant
-decreased insulin release or effectiveness |
