Question:

Which of the following causes bone matrix resorption during bone growth and remodeling?

A Osteoclasts
explanation

Osteoclasts are the resident macrophages of the bones, which are essential for bone matrix resorption during bone growth and remodeling. Osteoblasts are the cells responsible for bone matrix synthesis and calcification, while osteocytes are responsible for maintenance of calcified bone matrix. Osteons are the structural unit of compact bone characterized by concentric bone layers surrounding a central canal.
