$$Bone\ Mass = Bone\ Density \times Bone\ Volume$$

Question 1

Which structure in a typical long bone is responsible for the production of blood cells in adults?

Accepted Answer

Spongy bone

Question 2

What is the primary function of the periosteum in long bones?

Accepted Answer

To serve as an attachment point for tendons and ligaments and supply blood to bone

Question 3

Which region of a long bone contains the epiphyseal line, and what is its significance?

Accepted Answer

Proximal epiphysis; it is the remnant of the growth plate

Question 4

A patient suffers a fracture at the shaft of the femur. Which anatomical term best describes the location of this injury?

Accepted Answer

Diaphysis

Question 5

Which of the following best describes the difference between compact bone and spongy bone?

Accepted Answer

Compact bone is dense and forms the outer layer of bones, while spongy bone is porous and found in the epiphyses

Question 6

Which structure is responsible for the smooth movement of joints and is found covering the ends of long bones?

Accepted Answer

Articular cartilage

Question 7

During bone growth, which structure is responsible for lengthwise growth in children and adolescents?

Accepted Answer

Epiphyseal plate

Question 8

Which of the following best describes the function of Sharpey's (perforating) fibers?

Accepted Answer

They connect the periosteum to the underlying compact bone

Question 9

A patient with osteoporosis is at increased risk for fractures in which part of the long bone due to its porous structure?

Accepted Answer

Spongy bone

Question 10

Which of the following equations correctly represents the relationship between bone mass, bone density, and bone volume?

Accepted Answer

$$Bone\ Mass = Bone\ Density 	imes Bone\ Volume$$

Question 11

Which structure lines the inner surface of the medullary cavity and is involved in bone growth, repair, and remodeling?

Accepted Answer

Endosteum

Question 12

If a nutrient artery is blocked, which part of the long bone is most likely to be affected first?

Accepted Answer

Compact bone

Question 13

Which of the following best explains why the medullary cavity contains yellow marrow in adults?

Accepted Answer

Yellow marrow stores fat for energy

Question 14

A child presents with a fracture that disrupts the epiphyseal plate. What is the most likely long-term consequence if not properly treated?

Accepted Answer

Impaired bone lengthening and possible limb length discrepancy

Question 15

Which anatomical feature is most responsible for the resistance of long bones to bending forces?

Accepted Answer

Compact bone
