Question 1

Which of the following best describes the primary function of osteoclasts in bone tissue?

Accepted Answer

They break down bone matrix, releasing calcium into the blood.

Question 2

A 12-year-old patient suffers a fracture that disrupts the epiphyseal plate. Which of the following is the most likely long-term consequence if the fracture is not properly treated?

Accepted Answer

The bone may stop growing in length, resulting in a shorter limb.

Question 3

Which hormone increases blood calcium levels by stimulating osteoclast activity and bone resorption?

Accepted Answer

Parathyroid hormone (PTH)

Question 4

Which of the following best distinguishes compact bone from spongy bone?

Accepted Answer

Compact bone is organized into osteons, while spongy bone is composed of trabeculae.

Question 5

Which of the following equations correctly represents the chemical formula for hydroxyapatite, the main inorganic component of bone matrix?

Accepted Answer

$$ \mathrm{Ca}_{10}(\mathrm{PO}_4)_6(\mathrm{OH})_2 $$

Question 6

During intramembranous ossification, which tissue type is first replaced by bone?

Accepted Answer

Fibrous connective tissue (mesenchyme)

Question 7

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

Accepted Answer

Bone grows in diameter by adding new bone to the surface.

Question 8

A patient presents with a greenstick fracture. Which of the following best describes this type of fracture?

Accepted Answer

The bone is partially broken and bends on the other side, common in children.

Question 9

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

Accepted Answer

Hormone synthesis

Question 10

Which of the following correctly matches the bone type with an example?

Accepted Answer

Sesamoid bone – patella

Question 11

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

Accepted Answer

It covers the outer surface of bone and contains blood vessels and nerves.

Question 12

Which of the following best explains why osteoporosis is more common in postmenopausal women?

Accepted Answer

Decreased estrogen leads to increased osteoclast activity and bone resorption.

Question 13

Which of the following is the correct sequence of events in fracture repair?

Accepted Answer

Hematoma → Soft callus → Bone callus (primary bone) → Secondary bone

Question 14

Which of the following best describes the difference between red and yellow bone marrow?

Accepted Answer

Red marrow produces blood cells, while yellow marrow stores fat.

Question 15

Which of the following zones of the epiphyseal plate is responsible for the rapid division of chondrocytes during longitudinal bone growth?

Accepted Answer

Zone of proliferation

Question 16

A patient with a comminuted fracture has which of the following?

Accepted Answer

A bone that is broken into three or more pieces

Question 17

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

Accepted Answer

They maintain bone matrix and communicate with other bone cells via canaliculi.

Question 18

Which process is primarily responsible for the formation of most bones in the human body, such as the femur and humerus?

Accepted Answer

Endochondral ossification

Question 19

Which of the following structures allows blood vessels and nerves to travel from the periosteum into the compact bone?

Accepted Answer

Perforating canal

Question 20

A patient with a spiral fracture most likely sustained the injury through which of the following mechanisms?

Accepted Answer

A twisting force applied to the bone
