Bone remodelling relies on the correct function of two principal cells of the bone tissue: the osteoclasts, multinucleated cells that destroy the bone matrix, and the osteoblasts, having osteogenic functions.
Which cells remodel bone quizlet?
 Two main types of cells are responsible for bone metabolism: osteoblasts (which secrete new bone), and osteoclasts (which break bone down).
Which controls bone remodeling quizlet?
The hormone that is primarily involved in the control of bone remodeling is the parathyroid hormone.
Where does bone remodeling occur?
Bone remodeling takes place in what Frost termed the Basic Multicellular Unit (BMU), which comprises the osteoclasts, osteoblasts, and osteocytes within the bone-remodeling cavity (Fig. 1). In cancellous bone remodeling occurs on the surface of trabeculae and lasts about 200 days in normal bone.
Are osteoblasts involved in bone Remodelling?
What is the role of osteoclasts in bone remodeling?
Osteoclasts are the cells that degrade bone to initiate normal bone remodeling and mediate bone loss in pathologic conditions by increasing their resorptive activity. They are derived from precursors in the myeloid/ monocyte lineage that circulate in the blood after their formation in the bone marrow.
