stimulus
High levels of blood glucose stimulate which hormone located in the pancreas?
insulin
the ovaries and testes are the target organs for which anterior pituitary hormone?
LH, FSH
high estrogen, high testosterone inhibit
FSH
a hyposecretion of Insulin can lead to what diseases?
DM type 1 and 2
the zone glomurelosa of the adrenal cortex secretes :
- mineralocorticoids, mostly aldosterone
osmoreceptors in the hypothalamus that sense a decrease in blood volume and increase in blood solute concentration stimulate which posterior pituitary hormone?
ADH
ADH targets the _______ by doing what?
Kidneys: causes kidneys to reabsorb h20 to increase blood volume and BP
Insulin is inhibited by
- low blood glucose
failure of sexual maturation is a disease caused by a hypo secretion of which hormones?
LF, FSH
what type of cells are found in the pancreas that secrete Insulin?
Beta cells- islets of Langerhan's
Gonadotropin releasing hormone (GnRH) from the hypothalamus is the stimulus for which hormones?
These hormones are located in which portion of the hypophysis?
- Luteinizing hormone & Follicle- stimulating hormone
- located in the adenohypophysis/ anterior pituitary
This hormone causes the liver to break down glycogen to glucose
Glucagon
lack of neural stimuli inhibit which hormones?
ADH, OT
A hypo secretion of ADH is linked to which disease?
- DM Insipidus
the thyroid gland triggers the release of ?
T3 and T4
Glucagon is stimulated by?
- low levels of glucose
- high amino acid levels
What are the target organs to OT?
Uterus: myometrium
Breast: myoepithelium, causes contractions for birth and milk letdown
high estrogen, testosterone, and progesterone inhibit
LH
A hypersecretion of ADH is linked to what disease?
Cushings disease
Growth hormone is linked to what 3 main diseases?
hyper secretion: acromegaly and gigantism
hypo secretion: pituitary dwarfism
What hormone is stimulated by an increase in stretch r/c in the cervix, uterus, nipples?
Oxytocin
Liver: inhibits production of glucose
Tissue cells: gets glucose into cells by increasing permeability of cell membrane
Insulin
Glucagon is inhibited by
- high blood glucose
- low levels of amino acid
Addisons disease is caused by _________ levels of which hormone?
low levels of Aldosterone
Pheochromocytoma ( tumor in the medulla) is caused by ______ levels of which adrenal medulla hormones?
