Skeletal System, Osteon Questions and
Answers Graded A+
How do osteons help bones resist pressure and weight?
✔✔Osteons are arranged in a way that aligns with the direction of the forces placed on the bone,
providing optimal strength.
What structural feature of the osteon is responsible for its strength and resilience?
✔✔The concentric lamellae, which form a dense, organized structure around the central canal.
What is the primary function of the lacunae in osteons?
✔✔Lacunae house the osteocytes, allowing them to stay embedded within the bone matrix.
How do osteocytes contribute to bone maintenance and health?
✔✔Osteocytes maintain bone homeostasis by regulating mineral content and assisting in bone
remodeling.
What happens when osteoclast activity exceeds osteoblast activity in bone tissue?
1
, ✔✔Excessive osteoclast activity can lead to bone loss, potentially causing conditions like
osteoporosis.
What role do the canaliculi play in the communication between osteocytes?
✔✔Canaliculi allow osteocytes to send signals and share nutrients, facilitating coordinated bone
maintenance.
How is the structure of the osteon designed to resist mechanical fatigue over time?
✔✔The layered structure of the osteon distributes stresses evenly, preventing cracks from
spreading through the bone.
Why are osteons particularly found in compact bone rather than spongy bone?
✔✔Osteons are characteristic of compact bone, where dense, solid bone tissue is needed to
withstand stress and pressure.
What is the key difference between osteons and trabeculae in terms of bone structure?
✔✔Osteons are cylindrical structures found in compact bone, while trabeculae are a network of
interwoven beams found in spongy bone.
