Glands and Communication
In general, is the endocrine system usually fast or slow in its effects?
slow
This hormone needs to bind to a transport protein.
steroid
increased heat, SNS response, effects of GH
Which hormone stimulates the anterior pituitary gland to release GH?
GHRH
Alpha cells make this hormone, while beta cells make this hormone.
Which general type of gland uses ducts to put secretions on the surface or into a tract?
exocrine
This hormone is hydrophilic.
peptide
What would happen to TRH and TSH if there was no TH present? What is this called?
both decrease; hypothyroidism
What are the general functions of GH?
bone and muscle growth
During a meal, which hormone is active?
insulin
What is the function of a paracrine agent?
acts on nearby tissues
This hormone binds to extracellular receptors.
peptide
The symptoms for this condition include nervousness, insomnia, weight loss, increased heart rate, and heat intolerance.
hyperthyroidism
The liver secretes what hormone?
IGF
Having this condition means having desensitized insulin receptors.
diabetes mellitus type II
True or false: Only cells with a receptor for a hormone will respond to that hormone.
true
Thyroid hormone is an example of this type of hormone.
monoamine
What would happen to TRH and TH respectively if TSH were no longer secreted in the pathway?
increase; decrease
Describe acromegaly.
hypersecretion of GH after epiphyseal plates close; symptoms: bone thickening, enlarged organs, increased blood glucose
glucagon; to increase blood glucose
Describe endocrine glands.
do not use ducts and secrete into blood
Testosterone is an example of this type of hormone.
steroid
What is the purpose of negative feedback in this pathway?
prevent the hypothalamus and the anterior pituitary from secreting their hormones when there is enough TH
When there is a lot of IGF, how does somatostatin counteract this?
IGF causes the hypothalamus to secrete somatostatin, which inhibits the anterior pituitary from releasing GH
Besides decreasing blood glucose, what else can insulin do?
store nutrients, convert glucose to glycogen, fat storage, protein synthesis
