Bone remodeling is a physiological process in which old or damaged bone is removed by osteoclasts (i.e., bone-resorbing cells), then replaced by new bone formed by osteoblasts (i.e., bone-forming cells).
What are the 3 main things that affect bone remodeling?
Bone remodeling is thought to be regulated by many factors including nutritional status, humoral factors, and biomechanical stress. However, the involvement of the autonomic nervous system, mainly the sympathetic nervous system (SNS), in the modulation of bone remodeling is beginning to receive more attention.
What is bone remodeling best described as quizlet?
Bone remodeling (or bone metabolism) is a lifelong process where mature bone tissue is removed from the skeleton (a process called bone resorption) and new bone tissue is formed (a process called ossification or new bone formation).
What are the functions of bone remodeling quizlet?
All of the above (Bone remodeling functions to repair damaged bone, recycle bone tissue, and maintain blood calcium levels.)
What are the main stages of bone remodeling?
The remodelling cycle occurs within the basic multicellular unit and comprises five co-ordinated steps; activation, resorption, reversal, formation and termination. These steps occur simultaneously but asynchronously at multiple different locations within the skeleton.
What contributes to bone remodeling and growth?
The regulation of bone remodeling is both systemic and local. The major systemic regulators include parathyroid hormone (PTH), calcitriol, and other hormones such as growth hormone, glucocorticoids, thyroid hormones, and sex hormones.
