c)

Deposition in remodeling involves

d)

b)

Remodeling

c)

d)

3.

Resorption in remodeling involves

a)

When blood Ca drops it stimulates parathyroid gland which releases parathyroid hormone (PTH); PTH activates osteoclasts which destroy bony matrix and release Ca which increases blood Ca+levels until homeostasis; negative feedback stops process.

b)

New bone is more resistant to fracture.

c)

Addition of minerals and collagen fibers by osteoblasts.

d)

removal of minerals and collagen fibers by osteoclasts.

4.

Deposition in remodeling involves

a)

Regenerates Ca and P levels in blood.

b)

Provides bone with continued strength

c)

Addition of minerals and collagen fibers by osteoblasts.

d)

muscle tremors or spasmslaryngospasm can cause suffocation.

7.

When blood Ca drops it stimulates parathyroid gland which releases parathyroid hormone (PTH); PTH activates osteoclasts which destroy bony matrix and release Ca which increases blood Ca+levels until homeostasis; negative feedback stops process.
