Question 1

Which of the following is NOT a function of the skeletal system?

Accepted Answer

Hormone production

Question 2

Which type of bone is best described as being longer than it is wide and contains a diaphysis and epiphyses?

Accepted Answer

Long bone

Question 3

A patient presents with a hunched posture, brittle bones, and frequent hip fractures. Which condition is most likely responsible, and what is a key preventative measure?

Accepted Answer

Osteoporosis; weight-bearing exercise

Question 4

Which hormone is secreted when blood calcium levels are too high, and what is its effect on bone?

Accepted Answer

Calcitonin; stimulates osteoblasts

Question 5

During bone development, which cells are responsible for forming the initial cartilage model of future bone?

Accepted Answer

Chondroblasts

Question 6

A compound fracture is best described as:

Accepted Answer

A break where bone ends or shards puncture the skin

Question 7

Which structure in a long bone contains red bone marrow and is the site of blood cell formation?

Accepted Answer

Epiphysis

Question 8

What is the primary function of osteoclasts in bone remodeling?

Accepted Answer

Dissolving bone matrix and releasing calcium

Question 9

A patient with carpal tunnel syndrome is most likely experiencing compression of which structure?

Accepted Answer

Median nerve

Question 10

Which of the following best explains why weight-bearing exercise is recommended for osteoporosis prevention?

Accepted Answer

It increases compressive force, stimulating osteoblasts to deposit new bone

Question 11

Which bone is part of the axial skeleton?

Accepted Answer

Sternum

Question 12

A child’s long bone is lengthening. Which structure is primarily responsible for this growth?

Accepted Answer

Epiphyseal plate

Question 13

Which of the following best describes the difference between osteoarthritis and rheumatoid arthritis?

Accepted Answer

Osteoarthritis involves cartilage wear; rheumatoid arthritis involves immune attack on synovial membrane

Question 14

Which of the following equations best represents the relationship between bone resorption and formation in osteoporosis?

Accepted Answer

$$	ext{Osteoclast~activity} \u003e 	ext{Osteoblast~activity}$$

Question 15

Which of the following is a correct sequence of events in the repair of a broken bone?

Accepted Answer

Hematoma formation → chondroblast callus formation → osteoclast removal of debris → osteoblast bone deposition

Question 16

Which of the following best describes the function of the periosteum?

Accepted Answer

It covers the outer surface of bone and contains bone-forming cells

Question 17

A patient is diagnosed with bursitis in the shoulder. Which structure is inflamed?

Accepted Answer

Bursa

Question 18

Which of the following best explains the role of canaliculi in bone tissue?

Accepted Answer

They allow osteocytes to exchange nutrients and communicate

Question 19

Which of the following is a correct description of a ligament?

Accepted Answer

Connects bone to bone

Question 20
