Bone Hormones Quiz

How does osteocalcin contribute to the regulation of blood sugar and fat deposition?

• Osteocalcin only affects blood sugar but not fat deposition.

• Osteocalcin has no effect on blood sugar and fat deposition.

• Osteocalcin promotes insulin production and sensitivity, increases energy expenditure, and reduces fat accumulation.

• Osteocalcin inhibits insulin production and sensitivity, decreases energy expenditure, and increases fat accumulation.

What are the effects of parathyroid hormone on bone?

• Increases bone resorption

• Has no effect on bone

• Causes bone growth

• Decreases bone resorption

How does parathyroid hormone regulate calcium levels in the body?

• By promoting the release of calcium from the bones and increasing calcium absorption in the intestines.

• By promoting the excretion of calcium through the kidneys

• By inhibiting the release of calcium from the bones

• By decreasing calcium absorption in the intestines

What is the impact of estrogen on bone density?

• Estrogen helps to maintain bone density by inhibiting bone resorption and promoting bone formation.

• Estrogen only affects muscle strength, not bone density

• Estrogen decreases bone density

• Estrogen has no impact on bone density

How does estrogen affect the rate of bone resorption and formation?

• Estrogen decreases the rate of bone resorption and increases the rate of bone formation.

• Estrogen has no effect on bone resorption and formation

• Estrogen only increases the rate of bone resorption

• Estrogen only decreases the rate of bone formation

What is the function of calcitonin in bone regulation?

• Increases the production of red blood cells

• Regulates calcium and phosphate levels in the blood

• Promotes the absorption of calcium and phosphate in the intestines

• Stimulates the breakdown of bone tissue

How does calcitonin help to maintain calcium levels in the blood?

• Inhibiting the activity of osteoclasts

• Increasing the absorption of calcium in the intestines

• Stimulating the activity of osteoclasts

• Promoting the release of calcium from the kidneys

What is the influence of vitamin D on bone health?

• Vitamin D helps in the absorption of calcium and phosphorus, which are essential for maintaining strong and healthy bones.

• Vitamin D has no impact on bone health

• Vitamin D only affects muscle health

• Vitamin D causes bone weakness

How does vitamin D promote calcium absorption in the intestines and mineralization of bone?

• Vitamin D inhibits calcium absorption in the intestines

• Vitamin D has no effect on calcium and phosphate levels

• Vitamin D regulates calcium and phosphate levels in the body.

• Vitamin D promotes iron absorption in the intestines

What is a hypocalcemic blood level?
