Questions: Bone remodeling involves the coordination of which two types of cells? Osteoclasts and fibroblasts Osteons and canaliculi Osteoblasts and osteoclasts Chondroblasts and osteoclasts

The answer is the third one: Osteoblasts and osteoclasts.

Explanation for each option:

1. Osteoclasts and fibroblasts: Incorrect. Osteoclasts are involved in bone resorption, but fibroblasts are primarily involved in the formation of connective tissue, not bone remodeling.
2. Osteons and canaliculi: Incorrect. Osteons are structural units of compact bone, and canaliculi are small channels within the bone. Neither are cell types involved in bone remodeling.
3. Osteoblasts and osteoclasts: Correct. Osteoblasts are responsible for bone formation, while osteoclasts are responsible for bone resorption. The coordination between these two cell types is essential for bone remodeling.
4. Chondroblasts and osteoclasts: Incorrect. Chondroblasts are involved in cartilage formation, not bone remodeling.

Summary: Bone remodeling involves the coordination of osteoblasts and osteoclasts.
