Growth and Thyroid Hormone

[reyrey389]

1) Growth hormone and thyroid hormone both stimulate protein synthesis and osteoblast activity?
My notes had somewhat similar definitions for both of these, I was wondering are growth hormones and thyroid both the same? Or are they different, but they both increase the rat e of protein synthesis and osteoblast activity?

2) Also, I was mixing up the function of thyroid and parathyroid hormones.
Does thyroid secrete calcitonin to lower blood levels
and parathyroid secrete calcium/phosphates to raise blood levels?



Ty, any help would be appreciated.

1) they are not the same, growth hormones are usually peptides, while thyroid are not

2) parathyroid hormones should increase level of calcium
