QuestionAnswer
hormone that arise form axon terminal instead of endocrine cells are known as _____.
thyroid hormone are formed by adding what molecule to tyrosine?
10% of circulatory T3 and T4 is bound to what protein?
steroid hormones are released from cells via (diffusion or exocytosis?)
One possible cause of this disorder can be the binding of autoantibodies to the TSH receptor preventing the release of thyroid hormones.
This hormone acts to increase iodine uptake via NIS, activates thyroid peroxidase, increases the production of thyroglobulin, and increases the secretion of T3 and T4.
hyperthyroidism cause by the binding of an autoantibody to the TSH receptor.
True or False: Metabolism and Feedback Regulation are key in control of the endocrine system.
what molecule is bound to a G protein in its inactive form?
True or False: Protein or peptide hormones have a short half-life
intracellular receptors for estrogen and progesterone are primarily located where within a cell?
What percentage of the ingested iodine actually makes it to the thyroid?
The thyroid gland synthesizes T4 ___% of the time.
Where is TSH made? (Be specific)
this receptor type opens as a channel in response to ligand binding
what transporter is responsible for actively moving iodine into the thyroid gland?
water soluble hormones generally bind to receptors that are located where?
True or False: The thyroid hormones pre-dominantly travel in the blood in free form.
this disorder occurs when the G alpha stimulatory subunt of the PTH receptor is defective and causes the patient to have hypocalcemia.
intracellular receptors for glucocorticoid and mineralcorticoid are primarily located where within a cell?
In order to maintain, normal thyroid function we must ingest how much iodine per week (in mg)?
abnormal disorder of the thyroid that is characterized by increased appetite, weight loss, heat intolerance, and increased sweating.
protein/ peptide hormones are released from cells via (diffusion or exocytosis?)
Which thyroid hormone is responsible for the negative feedback regulation of TRH and TSH?
found in the apical membrane of the follicular cells and is responsible for transporting iodine from the follicular cells into the lumen of the thyroid follicle.
the addition of two iodine to tyrosine results in what molecule?
True or False: During times of starvation, the biologically inactive r-T3 is produced to conserve energy stores.
The release of TSH is stimulated by what?
QuestionAnswer
a system of chemical messengers that are released into the interstitial fluid to act on adjacent cells is known as _____
which tyrosine derived group of hormones act similar to steroid hormones
70% of circulatory T3 and T4 is bound to what protein?
the addition of one iodine to tyrosine results in what molecule?
a system of chemical messengers that are released into the interstitial fluid to act on itself is known as _____
When there is an iodine deficiency, the percentage of T4 made increases or decreases?
TRH is made in the ______ and the _____ nuclei of the hypothalamus.
The thyroid hormones are released into circulation via what process?
chemical messengers that are transported by the blood to act on target organs and cells.
patients with iodine deficiency have a higher or lower plasma TSH level?
True or False: The thyroid hormones are made within the thyroid epithelial cells.
True or False: T3 promotes the storage of energy.
True or False: The half life of T3 is longer than T4.
catalyzes the conversion of T4 to T3
an increase in basal metabolic rate is known as ______. It is regulated by Thyroid hormones.
When there is an iodine deficiency, the total amount of thyroid hormone produced increases or decreases?
20% of circulatory T3 and T4 is bound to what protein?
enzyme responsible for the liberation of iodine and the iodination of tyrosine to produce the thyroid hormones
True or False: The thyroid hormone binding proteins serve to protect T3 and T4 from metabolism and excretion. They also allow for large pools of readily available hormone in the bl
intracellular receptors for thyroid hormones are primarily bound to what?
Calcitonin can be found in the _______ cells of the thyroid.
this disorder occurs due to a defective V2 receptor in the kidney that causes an inability to retain water.
When there is an iodine deficiency, the percentage of T3 made increases or decreases?
patients with graves disease have a higher or lower plasma TSH level?
which tyrosine derived group of hormones act similar to protein/ peptide hormones
abnormal disorder of the thyroid that is characterized by decreased appetite, weight gain, cold intolerance, and decreased sweating
lipid soluble hormones generally bind to what types of receptors?
