Term
How is are steroid hormones transported in the blood? |
|
Definition
Largely bound to albumin, some are dissolved in plasma as free hormones. |
|
|
Term
How are peptide hormones transported in the blood? |
|
Definition
largely dissolved in plasma |
|
|
Term
4 methods for clearance of hormones |
|
Definition
Excreted in urine or feces, inactivated by metabolism, activated by metabolism, bind to receptor and produce a cellular response. |
|
|
Term
Regulation of hormone receptors |
|
Definition
Down-regulation with high concentration of hormone, Up-regulation with low concentration of hormone. |
|
|
Term
Thyroid example of Permissive role of hormone |
|
Definition
thyroid hormone can help up regulate epinephrine receptors to achieve epinephrine breakdown that would normally be unattainable without thyroid hormone. |
|
|
Term
T/F Epinephrine is capable of high levels of Fatty Acid breakdown without thyroid hormone present. |
|
Definition
False. The permissive role of thyroid hormone with epinephrine allows high levels of FFA breakdown to occur. |
|
|
Term
T/F. Peptide hormones and other water soluble hormones interact with receptors on the plasma membrane and are involved in rapid cellular response. |
|
Definition
|
|
Term
T/F. Steroid Hormones interact with reeceptors located on plasma membrane and are involved in rapid response. |
|
Definition
False. Steroid hormones interact with intracellular receptors on nuclear membrane, affect gene activity with slower physiological response. |
|
|
Term
3 things capable of altering rate of hormone secretion |
|
Definition
Ions/nutrients, Neurotransmitters, Hormones. |
|
|
Term
|
Definition
Partial destruction of gland, decreased synthesis ofhormone due to lack of necessary enzyme, dietary deficiency of iodine. |
|
|
Term
|
Definition
No damage on gland itself, but lack of its tropic hormones. |
|
|
Term
Will Primary hyposecretion respond to tropic hormone administration? |
|
Definition
No. The gland has been destroyed or is intrinsically incapable of producing the hormone no matter how much it is stimulated to do so. |
|
|
Term
Will secondary hyposecretion respond to tropic hormone? |
|
Definition
Yes. Secondary hyposecretion occurs as a result of tropic hormone deficiency. Therefore, if the hormone is supplied by injection then the gland should respond to the tropic hormone and normal function would continue. |
|
|
Term
|
Definition
the gland secretes too much hormone |
|
|
Term
|
Definition
The gland is stimultaed by its tropic hormone to produce too much hormone. |
|
|
Term
What is the common cause of hypersecretion? |
|
Definition
The presence of endocrine cell tumor. |
|
|
Term
Will there be high or low levels of tropic hormone in primary hypersecretion? |
|
Definition
|
|
Term
Will there be high or low levels of tropic hormone in secondary hypersecretion? |
|
Definition
|
|
Term
|
Definition
REduced hormone receptors on target cells. abnormality in intracellular signaling proteins. lack of enzyme in activating hormone product. In general hormone in plasma is elevated in the presence of hyporesponsiveness. |

Term
Does the Anterior Pituitary Gland have direct neural connection with hypothalamus? |
|
Definition
|
|
Term
What kind of connection does the posterior pituitary have with the hypothalamus? |
|
Definition
|
|
Term
What function does the infundibulum have in teh hypothalamo-pituitary gland? |
|
Definition
It connects the pituitary gland and the hypothalamus. |
|
|
Term
Hypophysiotropic Hormones from Hypothalamus |
|
Definition
Coricotropin-releasing Hormone, Thyrotropin-releasing hormone, Gonadotropin-releasing hormone, growth hormone-releasing hormone, growth hormone release-inhibiting hormone, prolactin-releasing hormone, prolactin release-inhibiting hormone(dopamine) |
|
|
Term
T/F Dopamine serves as the major prolactin release-inhibiting hormone. |
