T3, T4   show TSH secreted by anterior pituitary gland in response to low T3, T4 serum levels   All body tissue   Increased availability of beta receptors, Controls: Metabolism, Caloric use, O2 consumption, CHO metabolism, Fat metabolism, Protein catabolism, Growth, Cell differentiation, Brain and CNS activity   Hyperthyroid, Graves, Thyroid Storm   Hypothyroid, Myxedema Coma  
🗑
Calcitonin   Thyroid   High serum calcium   show Decreased serum calcium via: Inhibition of release of calcium, from bones/ bone resorption, Increased calcium storage in bone, Increased renal excretion of calcium   n/a   n/a  
🗑
PTH   Parathyroid glands   show Bone, kidneys, small intestine   Increased serum calcium via: Stimulation of bone resorption and inhibition of bone formation, Increased renal calcium absorption, Increased renal conversion of Calcidiol to Vitamin D, Increased calcium reabsorption from the GI tract   Hyperparathyroid, hypercalcemia   Hypoparathyroid, Hypocalcemia  
🗑
Aldosterone   Adrenal cortex   ACTH from the anterior pituitary, renin-angiotensin, or high serum K   Kidneys   Sodium and water retention, Potassium excretion   Hyperaldosterone, Conn's   show
🗑
Androgen   Adrenal cortex   ACTH secreted from anterior pituitary   Organs associated with secondary sex characteristics: breasts, vocal cords, anything not needed for reproduction   Development of non-reproductive sex characteristics   show Addison's (in combination with Cortisol and Androgen decrease)

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
 
To hide a column, click on the column name.
 
To hide the entire table, click on the "Hide All" button.
 
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
 
Or sort by any of the columns using the down arrow next to any column heading.
