Osteology Exam Questions and Answers
Graded A+
What is the primary function of osteoblasts in bone formation?
✔✔Osteoblasts are responsible for the synthesis and mineralization of bone matrix.
What is the significance of the trabecular bone in long bones?
✔✔Trabecular bone helps to reduce the weight of the bone while maintaining strength and
providing support.
How does the process of bone remodeling contribute to bone health?
✔✔Bone remodeling involves the continuous replacement of old bone tissue with new tissue,
helping to maintain bone strength and adapt to stress.
What role does calcium play in bone formation?
✔✔Calcium is essential for bone mineralization, providing strength and structure to the bone
matrix.
What is the function of osteoclasts in bone resorption?
1
,✔✔Osteoclasts break down bone tissue, releasing calcium and phosphate into the bloodstream
and allowing for bone remodeling.
What is the main difference between compact bone and spongy bone in structure?
✔✔Compact bone is dense and forms the outer layer of bones, while spongy bone has a porous
structure and is found at the ends of long bones and inside others.
How does vitamin D influence bone health?
✔✔Vitamin D enhances calcium absorption in the intestines, which is crucial for maintaining
healthy bone density.
What is the term for the condition where bones become brittle and fragile due to mineral loss?
✔✔Osteoporosis is the condition where bones become brittle and fragile due to a decrease in
bone density.
What is the role of the periosteum in bone health?
✔✔The periosteum is a dense layer of connective tissue that covers the outer surface of bones,
providing nutrients, and housing bone cells for growth and repair.
2
, What is the purpose of the medullary cavity in long bones?
✔✔The medullary cavity stores bone marrow, which produces blood cells, and provides space to
reduce the weight of the bone.
How does mechanical stress affect bone density?
✔✔Mechanical stress stimulates bone formation and increases bone density, as the bone adapts
to handle the forces applied to it.
What is the process of ossification during bone development?
✔✔Ossification is the process by which bone tissue forms, either through intramembranous
ossification or endochondral ossification.
What is the significance of the epiphyseal plate in bone growth?
✔✔The epiphyseal plate, or growth plate, is where new bone cells are produced, allowing for the
lengthening of long bones during growth.
What is the role of collagen in bone structure?
✔✔Collagen fibers provide flexibility and tensile strength to the bone matrix, preventing bones
from becoming too brittle.
