Practice Question
Which of the following cell types is responsible for secreting acids to dissolve the bony matrix?
Answer Choices:
Correct Answer:
Osteoclasts
Rationale:
🟥Osteoclasts are multinucleated bone-resorbing cells that secrete acids and proteolytic enzymes to dissolve the mineral and organic matrix.
🟥Their ruffled border creates a sealed resorption lacuna where H⁺ is pumped to acidify and decalcify bone.
🟥This process releases calcium and phosphate, contributing to mineral homeostasis.
🟥Bone remodeling depends on the balanced activity of osteoclasts (resorption) and osteoblasts (formation).
🟥Dysregulation of osteoclast function leads to skeletal pathology (e.g., osteoporosis, Paget disease).
