Practice Question
Which type of bone growth occurs throughout adulthood and is characterized by the change in the thickness (width) of the bone?
Answer Choices:
Correct Answer:
Remodeling
Rationale:
♻️Bone remodeling is a lifelong process in which osteoclasts resorb bone and osteoblasts lay down new bone, adjusting thickness/contour to mechanical loads.
♻️In adulthood, longitudinal growth stops, but appositional changes via remodeling can alter cortical width and trabecular architecture.
♻️Remodeling maintains calcium/phosphate homeostasis, repairs microdamage, and adapts skeleton to functional demands.
♻️Clinical influences include exercise (↑ formation), disuse (↑ resorption), and hormonal status (e.g., estrogen deficiency → net loss).
♻️Effective remodeling preserves bone strength and reduces fracture risk when balanced.
