where would you find the receptor for PTH?
| on the plasma membrane of target cells |
| on the plasma membrane of all cells |
| in the nucleus of target cells |
|
in the cytosol of target cells |
2.
Where in the parathyroid gland is PTH produced?
| parafollicular cells or C-cells |
| principal cells |
| oxyphils |
| follicular cells |
3.
Which hormone is the antagonist to PTH and functions to lower blood calcium levels?
| calcitriol |
| glucagon |
| calcitonin |
| estrogen |
Homework Answers
Question No.1
Answer :- on the plasma membrane of target cells.
Question No.2
Answer :- Principal cell
Explanation : Principal cells or chief cell secrete PTH .PTH
increases serum calcium by increasing bone resorption of calcium
into blood (this requires vitamin D).
Increases renal reabsorption of calcium.
Question No.3
Answer :- calcitonin
Explanation : Calcitonin Released in response to high blood calcium-->Lowers blood calcium-->osteoblast.
It Stimulate osteoblasts-->Inhibit osteoclasts-->Decrease calcium reabsorption by nephron -Result in maintain blood calcium level .
