The bone dissolving cells are called:
Correct answer: A. Osteoclast
- A. Osteoclast
- B. Osteoblasts
- C. Osteocytes
- D. Fibroblast
Explanation
Osteoclasts are the bone-dissolving cells responsible for bone resorption. Derived from monocytes, they are large, multinucleated cells that break down bone tissue by secreting enzymes and acids, creating resorption pits. This process is vital for bone remodeling and calcium release into the bloodstream. Osteoblasts then fill these pits with new bone tissue, maintaining bone health.The other cell types serve different functions: Osteoblasts create new bone tissue, osteocytes maintain the bone matrix, and fibroblasts are involved in the production of connective tissue, not bone resorption.
