Prolactin, Growth Hormone (GH), Thyriod-stimulating hormone (TSH), Follicle-stimulating hormone (FSH), Luteinizing Hormone (LH), and Adrenocorticotropic Hormone (ACTH)
What are the two hormones secreted by the posterior lobe of the pituitary gland?
Oxytocin and Antidiuretic Hormone (ADH)
Which pituitary hormone causes kidneys to conserve water?
Antidiuretic Hormone (ADH)
Which pituitary hormone stimulates cells to increase in size and divide more rapidly?
Growth Hormone (GH)
Which pituitary hormone stimulates secretion from thyroid gland?
Thyroid-Stimulating Hormone (TSH)
Which pituitary hormone causes contraction of uterine wall muscles?
Oxytocin
Which pituitary hormone stimulates secretion from adrenal cortex?
Adrenocorticotropic Hormone (ACTH)
Which pituitary hormone stimulates milk production?
Prolactin
What are the two thyroid hormones that affect metabolic rate?
Thyroxine and Triidothyronine
What is the hormone secreted by the thyroid gland that acts to lower blood calcium?
Calcitonin
What is the hormone that acts to raise blood calcium?
parathyroid hormone (PTH)
What are the three target organs of parathyroid hormone?
bones, intestines, and kidneys
What are the two hormones secreted by the adrenal medulla?
epinephrine and norepinephrine
What are the 5 different affects produced by these medullary hormones?
Heart rate, respiration, blood sugar concentration, metabolic rate
What is the most important mineralocorticoid secreted by the adrenal cortex?
Aldosterone
What are the 2 actions of aldosterone?
Kidney conservation of water and increases excretion of potassium in kidney conservation of sodium ions.
What is the most important glucocorticoid?
Cortisol
What are the 3 actions of cortisol?
Protein synthesis, release and use of fatty acid, and stimulates liver to produce glucose
What are the two hormones secreted by the alpha and beta cells of the islets of langerhans?
Insulin (beta) and Glucagon (alpha)
How do the actions of pancreatic hormones complement one another?
insulin and glucagon function together to stabilize blood glucose concentration via negative feedback loop.
