What are dark spots seen on a bone after a bone scan?
I'm not 100 percent sure, but I believe that the "dark spots", often called hot spots, refer to abnormal amounts of radionuclide in the bone, determining that it is infected or diseased. Though the previous person isn't completely wrong, it really depends on how the images are displayed. If there is a white background, anything dark = increase tracer uptake, which could be a multitude of things, from trauma (bruises), to fractures, to cancer. Other scans are performed to distinguish between the many possibilities. Basically the premise of a bone scan is to image the physiology of bones. The drug used for the scan is what your body uses to repair bones. Bones are constantly under repair due to old cells dying, and new cells taking their place so that is why the whole skeleton shows up. So, when there is an increase in the repair of bone, it wills how up brighter on the scan (if black background, it will be more white, and if white background, it will be more black). Hope that answers your question a tad better.
Is bone constantly renewed through a process of remodeling that consists of resorption and formation?
a two-stage process (resorption and formation) that occurs throughout life. In the resorption stage, old bone is broken down and removed by cells called osteoclasts. In the formation stage, cells called osteoblasts build new bone to replace the old
What is the destruction of matrix osteoclasts?
The destruction of matrix by osteoclasts involves the secretion of acid and enzymes, such as cathepsin K, that break down the mineral and collagen components of bone matrix. This process is essential for bone resorption, where old or damaged bone is broken down to be replaced by new bone formation.
What refers to the two step process to which bone tissue is recycled?
Bone remodeling refers to the two-step process in which bone tissue is constantly broken down and rebuilt by specialized cells called osteoclasts and osteoblasts. Osteoclasts break down old or damaged bone tissue in a process called resorption, while osteoblasts build new bone tissue in a process called formation.
The remodeling of bone is a function of which cells?
Bone remodeling is primarily carried out by two types of cells: osteoblasts, which build new bone tissue, and osteoclasts, which break down old or damaged bone tissue. These cells work in a coordinated manner to maintain the balance between bone formation and resorption in order to keep the skeletal system healthy and strong.
Can a 1 year old break a bone?
yes

What are osteoclasts responsible for?
They absorb (or resorb) bone. Bone is active living tissue that is constant remaking itself. The osteoclasts break down and resorb old bone while osteoblasts lay down new bone to take its place.
What causes spots on bones visible on ct scan?
Dark areas on the bones, also called hot spots can be due to cancer, but other medical conditions can also cause them to show up. Things like arthritis and old bone fractures are other possibilities.
What is the meaning of osteoclyte?
An osteocyte is a bone cell. It can live as long as the bone exists in the body, and it works to break down old bony matrix so that new matrix can take it's place.

Which is the bone people break most often and why?
clavicle is most commonly fractured. but in old females femur usually fractured at neck level.

In Old age bone may become?
When a person becomes older, there bones will become more dense. When bones are more dense, they can break easily.
How old is Adrián Bone?
As of June 2014, Adrián Bone is 25 years old.

Osteoclasts break down old or damaged bone tissue in a process called resorption, while osteoblasts build new bone tissue in a process called formation.
Are cells that digest old bone in preparation for new bone growth?
Osteoclasts. They are a type of phagocytic cell, similar to the macrophage.
