Question 1

Which of the following best describes the primary function of the axial skeleton?

Accepted Answer

It forms the central supporting axis of the body, protecting the brain, spinal cord, and thoracic organs.

Question 2

A patient suffers a fracture in the region of the vertebral column that articulates with the ribs. Which vertebral region is most likely affected?

Accepted Answer

Thoracic

Question 3

Which bone marking serves as a conduit for nerves and blood vessels?

Accepted Answer

Foramen

Question 4

Which of the following is a function of bone that is NOT shared by cartilage?

Accepted Answer

Serving as a site for hematopoiesis

Question 5

A long bone is characterized by which of the following features?

Accepted Answer

It has a shaft with two ends and is longer than it is wide.

Question 6

Which of the following equations best represents the relationship between bone mass ($$M$$), bone density ($$\rho$$), and bone volume ($$V$$)?

Accepted Answer

$$M = ho 	imes V$$

Question 7

A patient presents with a loss of bone density in the spongy bone of the vertebrae. Which of the following is a likely consequence?

Accepted Answer

Increased risk of compression fractures

Question 8

Which bone marking is correctly matched with its description?

Accepted Answer

Spine – a sharp, slender, often pointed projection

Question 9

The atlas (C1) vertebra is unique because it:

Accepted Answer

Lacks a body and supports the skull for nodding movements

Question 10

Which of the following best explains why bone is a better storage depot for calcium than cartilage?

Accepted Answer

Bone contains a higher proportion of hydroxyapatite crystals.

Question 11

A patient with a fractured mandible would have difficulty with which of the following functions?

Accepted Answer

Chewing

Question 12

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

Accepted Answer

Producing synovial fluid

Question 13

Which of the following bones is classified as an irregular bone?

Accepted Answer

Vertebra

Question 14

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

Accepted Answer

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

Question 15

Which of the following is a correct pairing of a bone marking and its function?

Accepted Answer

Condyle – articulation with another bone

Question 16

A patient is unable to nod their head 'yes' but can shake their head 'no.' Which vertebra is most likely damaged?

Accepted Answer

Atlas (C1)

Question 17

Which of the following best explains why the ribs are classified as part of the axial skeleton?

Accepted Answer

They form the central axis and protect vital organs such as the heart and lungs.

Question 18

Which of the following is a real-life consequence of a severe loss of spongy bone in the vertebral bodies?

Accepted Answer

Compression fractures leading to loss of height and kyphosis

Question 19

Which of the following best describes the function of the costal cartilages in the thoracic cage?

Accepted Answer

They connect the ribs to the sternum, allowing flexibility during respiration.

Question 20

Which of the following equations correctly represents the calculation of bone mineral density ($$BMD) $$given bone mineral content ($$BMC) $$and bone area ($$A$$)?

Accepted Answer

$$BMD = BMC / A$$
