Question 3

Which of the following is NOT a function of bone tissue?

Accepted Answer

Hormone synthesis

Question 4

Which bone marking is described as a large, blunt, irregularly shaped process found only on the femur?

Accepted Answer

Trochanter

Question 5

Compare compact and spongy bone: Which statement is correct regarding their structure and function?

Question 8

During intramembranous ossification, which bones are primarily formed?

Accepted Answer

Flat bones such as the skull and clavicle

Question 9

A child with vitamin D deficiency presents with bowed legs. Which condition is most likely, and what is the underlying cause?

Accepted Answer

Rickets; poor bone mineralization due to lack of calcium and phosphate

Question 10

Which process allows bones to increase in diameter during growth?

Accepted Answer

Appositional growth

Question 11

A 70-year-old woman suffers a hip fracture after a minor fall. Which bone disease is most likely responsible, and what is a common treatment?

Question 16

During endochondral ossification, what is the first step in the formation of a long bone?

Accepted Answer

Formation of a bone collar around the diaphysis of the hyaline cartilage model

Question 17

Which of the following best describes the role of collagen in bone tissue?

Accepted Answer

Contributes to bone flexibility and resistance to twisting

Question 18

A fracture that results in the bone being broken into three or more pieces is classified as which type?

Accepted Answer

Question 20

Which of the following is a distinguishing feature of fibrocartilage compared to hyaline and elastic cartilage?

Accepted Answer

Resists strong compression and tension due to thick collagen fibers
