Definition
PRL
Term
What stimulates mammary gland developments and stimulates milk production by mammary glands?
Definition
Prolactin
Term
What is PRL thought to do in males?
Definition
help regulate androgen production by making interstitial cells more sensitive to LH
Term
Prolactin production is inhibited by what?
Definition
prolactin-inhiiting hormone (PIH)
Term
What is the prolactin-inhibiting hormone known as?
Definition
the neurotransmitter dopamine
Term
What is another term for growth hormone (GH)?
Definition
somatrotropin
Term
What stimulates cells growth and replication by increasing the rate of protein synthesis?
Definition
growth hormone
Term
How does the stimulation of growth by GH occur?
Definition
as liver cells respond to presence of GH by synthesizing and releasing somatomedin
Term
What are somatomedin?
Definition
insulin-like growth factors
Term
What stimulates stem cell division and differentiation of daughter cells in epithelia and connective tissue?
Definition
GH
Term
Where does GH stimulates breakdown of triglycerides (glucose-sparing effect)?
Definition
adipose tissue
Term
What happens in the liver to the growth hormones?
Definition
GH stimulates breakdown of glycogen by liver cells and releases it into the bloodstream as glucose and blood glucose levels rise significantly
Term
What is it called when GH stimulates breakdown of glycogen by liver cells and releases it into bloodstream as glucose and blood glucose levels rise significantly?
Definition
diabetic effect
Term
What is synthetic melanocyte stimulating hormone (MSH)?
Definition
sunless tan
Term
posterior pituitary
Definition
neurohypophysis
Term
What manufactures antiduretic hormone (ADH) and oxytocin (OT) and they move along axons in infundibulum to the posterior lobe of pituitary where they are stored and secreted due to nerve impulses from the hypothalamus?
Definition
hypothalamus
Term
What is released in response to a rise in solute concentration i blood or fall in blood volume or blood pressure?
Definition
antidiuretic hormone (ADH)
Term
What does ADH function to do?
Definition
decrease the amount of water lost at kidneys
Term
What is ADH release inhibited by that increases fluid excretion following consumption?
Definition
alcohol
Term
What occurs in several forms (all characterized by excessive urine production-polyuria)?
Definition
diabetes
Term
What is one form of diabetes that occurs because the posterior lobe of the pituitary gland no longer releases adequate amounts of ADH?
Definition
diabetes insipidus
Term
What may severe cases of diabetes insipidus lead to?
Definition
10L of fluid loss per day, dehydration, electrolyte imbalances (fatal without treatment)
Term
How do you treat diabetes insipidus?
