Accepted Answer

Collagen fibers

Question 3

Which of the following best describes the process of appositional growth in cartilage?

Accepted Answer

New chondroblasts differentiate from the perichondrium and add matrix to the surface

Question 4

Which bone cell type is responsible for bone resorption and contains a ruffled border to increase surface area?

Accepted Answer

Osteoclast

Question 5

A child’s X-ray shows a visible epiphyseal plate. What does this indicate about the child’s bone growth?

Accepted Answer

The bone is still capable of growing in length

Question 6

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

Accepted Answer

Abundance of thick collagen fibers

Question 7

Which structure allows for the passage of blood vessels and nerves through compact bone?

Accepted Answer

Central (Haversian) canal

Question 8

During endochondral ossification, what is the primary function of the periosteal bud?

Accepted Answer

To bring blood vessels, nerves, and osteogenic cells into the cartilage model

Question 9

Which of the following best describes the arrangement of lamellae in an osteon?

Accepted Answer

Concentric rings surrounding a central canal

Question 10

A mutation prevents the formation of the endosteum in long bones. Which process would be most directly affected?

Accepted Answer

Bone remodeling and repair

Question 11

Which of the following equations correctly represents the relationship between bone mass, deposition, and resorption?

Question 13

A patient with a genetic defect in collagen synthesis would most likely present with which bone abnormality?

Accepted Answer

Bones that are brittle and fracture easily

Question 14

Which of the following best describes the function of canaliculi in compact bone?

Accepted Answer

They connect lacunae and allow for nutrient and waste exchange between osteocytes

Question 15

Which of the following zones of the epiphyseal plate is responsible for the longitudinal growth of long bones?

Accepted Answer
