Resorb and break down bone matrix

Question 13

Which of the following equations best represents the relationship between bone mass, bone formation, and bone resorption?

Accepted Answer

Question 14

A 10-year-old child is diagnosed with scoliosis. Which type of vertebral column curvature does this represent?

Accepted Answer

Pathological curvature

Question 15

Which process is responsible for the formation of most long bones in the body?

Accepted Answer

Endochondral ossification

Question 16

During calcium homeostasis, which hormone is released in response to low blood calcium levels, and what is its effect on bone?

Accepted Answer

Parathyroid hormone (PTH); increases bone resorption

Question 17

Which of the following best describes the role of the osteocyte?

Accepted Answer

Maintains bone tissue and communicates with other bone cells

Accepted Answer

Skeletal, digestive, and urinary systems

Question 19

Which of the following best describes the difference between endochondral and intramembranous ossification?

Accepted Answer

Endochondral ossification forms bone from a cartilage model, while intramembranous ossification forms bone directly from mesenchyme
