Question 1

Which of the following best describes the anatomical location and function of spongy bone?

Accepted Answer

Spongy bone is located in the epiphyses of long bones and flat bones, and its function is to reduce bone weight and house red marrow for hematopoiesis.

Question 2

Which cell type is primarily responsible for bone resorption, and what is the main chemical process involved?

Accepted Answer

Osteoclasts; they break down bone matrix by secreting acids and enzymes.

Question 3

A patient is diagnosed with osteoporosis. Which of the following interventions is most likely to help prevent further bone loss?

Accepted Answer

Increasing dietary calcium and engaging in weight-bearing exercise.

Question 4

Which hormone is most important for stimulating bone growth during infancy and childhood?

Accepted Answer

Growth hormone

Question 5

What is the primary function of the epiphyseal plate in a growing long bone?

Accepted Answer

It is the site of interstitial growth, allowing lengthening of the bone.

Question 6

Which of the following best defines an osteon?

Accepted Answer

A structural unit of compact bone consisting of concentric lamellae around a central canal.

Question 7

During bone formation, what is the role of vitamin D?

Accepted Answer

Vitamin D increases calcium absorption in the intestines, which is essential for bone mineralization.

Question 8

Which process is responsible for the formation of flat bones such as those in the skull?

Accepted Answer

Intramembranous ossification

Question 9

A fracture occurs in the diaphysis of a long bone. Which type of bone tissue is most likely affected?

Accepted Answer

Compact bone

Question 10

Which of the following is the most abundant type of skeletal cartilage?

Accepted Answer

Hyaline cartilage

Question 11

What is Wolff’s law regarding bone adaptation?

Accepted Answer

Bone grows and remodels in response to the forces or demands placed upon it.

Question 12

Which of the following best describes the function of Volkmann’s canals?

Accepted Answer

They connect adjacent osteons and allow passage of blood vessels and nerves perpendicular to the Haversian canals.

Question 13

A 45-year-old patient presents with bone pain and fever. Blood tests reveal a bacterial infection in the bone. What is the most likely diagnosis?

Accepted Answer

Osteomyelitis

Question 14

Which of the following best describes the process of oppositional growth in bone?

Accepted Answer

Bone increases in diameter by addition of new bone tissue to the periosteal surface.

Question 15

Which of the following is a function of the skeletal system?

Accepted Answer

Storage of minerals such as calcium and phosphate

Question 16

What is the role of parathyroid hormone (PTH) in bone physiology?

Accepted Answer

PTH stimulates osteoclasts to increase bone resorption, raising blood calcium levels.

Question 17

Which term describes the thin layer of spongy bone found between two layers of compact bone in flat bones?

Accepted Answer

Diploe

Question 18

A child is experiencing abnormal bone growth due to a deficiency in growth hormone. Which equation best represents the relationship between growth hormone and bone lengthening?

Accepted Answer

Bone lengthening rate $$= k 	imes [GH]$$, where $$k is a $$constant and $$[GH] is $$the concentration of growth hormone.

Question 19

Which of the following superficial bone markings is defined as a shallow depression?

Accepted Answer

Fossa

Question 20

Which process is responsible for the increase in bone length during infancy and youth?

Accepted Answer

Interstitial growth at the epiphyseal plate
