Bones can wear down - in a sense. Bones are not rock solid dead matter. Quite the contrary. A bone in a live human body is living tissue. They are also quite porous. Bones can get denser or less dense depending on circumstances. For example they will grow more dense if they are more heavily used and vice-versa. Bones can also lose density (break down) if there is a sufficient lack of calcium and/or vitamin D in your diet, i.e. osteoporosis.
or if that's not what you mean... cartlidge is in between the joints to stop them from grinding and wearing down, so movement will be smooth.

CoachBones are constantly being broken down and rebuilt through a process called remodeling, which helps maintain their strength and structure. Osteoclasts break down old bone, while osteoblasts build new bone. This constant turnover helps prevent bones from wearing down over time.

What is the location of osteoclasts?
Osteoclasts break down bone (osteo-=bone, -clast=breaks) and osteoblasts build bone. (-blast=builder). This osteoclasts is on the surface of the bone. Usually breaking down and building up of bone is in equilibrium.
What two hormones play a role in bone remodeling and blood calcium level?
I would imagine you are talking about breaking down and building up of bone. Osteoclasts, and osteoblasts. Two types of cells that are constantly breaking down and rebuilding bone. Osteoclasts break down the bone acidically. While osteoblasts rebuild bone, by secreting osteoid, that becomes mineralized.
Most bone cancers increase the activity of what?
Most bone cancers increase the activity of osteoclasts, which are cells responsible for breaking down and resorbing bone tissue. This leads to bone destruction and weakened bones in individuals with bone cancer.
What are the cells responsible for active erosion of bone minerals?
Osteoclasts are cells responsible for the active erosion of bone minerals. They break down bone tissue by secreting enzymes and acids that dissolve the mineral components of bone. This process is essential for bone remodeling and maintenance of bone density.
The bone resorbing cells are called?
Osteoclasts are the bone-resorbing cells responsible for breaking down and resorbing bone tissue. They play a critical role in bone remodeling and maintenance of calcium balance in the body.
