Summary Introduction
Introduction :
Hormones are molecules that are released into the bloodstream by one cell and travel all across the body to affect other cells. Certain hormones affect the bone composition and growth patterns by modulating the rates of chondrocyte, osteoblast, and osteoclast activity.

Which of the following is false?
parathyroid hormone is produced by the parathyroid gland
parathyroid hormone increases urination of calcium
Oparathyroid hormone stimulates osteoclasts
parathyroid hormone increases calcium concentration in the blood
How does Parathyroid Hormone elevate blood calcium levels?
by increasing the amount of CA2+ removed from the blood by the kidneys
by decreasing the amount of CA2+ absorbed from the gut into the blood
by increasing the number and activity of osteoclasts
by increasing the number and activity of osteoblasts
Bone remodeling is a lifelong process that is tightly regulated by factors including hormones that maintain blood calcium homeostasis. Compare and contrast the processes by which parathyroid hormone versus calcitonin regulates blood calcium levels.
