System Function Flashcards
Another name for the pituitary gland
Master Gland or hypophysis
What is the function of the hypothalamus?
Releasing hormones in portal circulation
names have releasing/inhibiting names
What all does the Anterior Pituitary gland release?
- Adrenocorticotropic hormone (ACTH)
- Thyroid- stimulating hormone (TSH)
- Follicle stimulating hormone (FSH)
- Luteinizing hormone (LH)
- Prolactin
- Growth hormone (GH)
What all does the Posterior Pituitary gland release?
- Oxytocin/ Pitocin
2. Antidiuretic hormone/ Vasopressin/ Desmopressin Acetate (DDAVP)
Where does Growth hormone (GH) go?
Bone & muscles
Where does Prolactin go?
Mammary glands
Where does Follicle stimulating hormone (FSH) & Luteinizing hormone (LH) go?
Testes or ovaries
Where does Thyroid- stimulating hormone (TSH) go?
Thyroid
Where does Adrenocorticotropic hormone (ACTH) go?
Adrenal cortex
What does Growth hormone (GH) do?
Stimulate closure of growth plate
Too much Growth hormone (GH) in children
Gigantism
Too much Growth hormone (GH) in adults
Acromegaly
Too little Growth hormone (GH)
Dwarfism
When does TSH stimulate secretion for T3 & T4?
Under stress or cold
How does alcohol effect the endocrine system?
Alcohol surpasses ADH which can increase output
How does the Antidiuretic Hormone work?
Increase amount of water reabsorbed by the kidneys which decreases urinary output therefore increases water in the blood to maintain blood volume & blood pressure
What is the most important daily regulators of metabolic rate?
Thyroid- stimulating hormone (TSH)
What does the thyroid secrete?
Thyroid- stimulating hormone (TSH) & Calciton
When is the thyroid stimulated to release calciton?
Hypercalcemia
What is the main job of the Parathyroid gland?
Secretion of Parathyroid Hormone (PTH)
When does Parathyroid Hormone (PTH) increase?
PTH increases with decreased plasma calcium levels (hypocalcemia)
CAP
Cushing’s Disease (cortex)
Addison’s (cortex)
Pheochromocytoma (medulla)
What deals with salt, sugar, sex?
Adrenal cortex
What does the Adrenal medulla secrete?
Catecholeamines > Epinephrine & norepinephrine
How does the adrenal cortex work with salt?
Promotes salt retention in the kidneys by releasing renin
If Cortisol is the main target organ of Adrenal cortex what does it do?
Affects sugar (carbohydrate) metabolism by stimulating gluconeogenesis to increase ability to produce energy
What is the function of Alpha cells from the Pancreas?
Produce glucagon
What is the function of Beta cells from the Pancreas?
Produce insulin
What is the function of F cells from the Pancreas?
Exocrine function
What is the function of Delta cells from the Pancreas?
Secrete somatostatin which inhibits secretion of both insulin and glucagon
Exocrine function
Produce digestive enzymes
What is the blood osmolality goal?
275-295
Said goal is 300 in class
What happens is blood osmolality is greater than 300?
Specific gravity will be increased
