What is the main difference between an osteoblast and Osteocyte?

What is the main difference between an osteoblast and Osteocyte?

The key difference between osteoblasts and osteocytes is that osteoblasts are a type of bone cells responsible for the formation of new bones while osteocytes are a type of bone cells that maintain the bone mass. Bone is a living and growing tissue that makes the skeleton of humans and other vertebrates.

How are osteoclasts different than osteoblasts and osteocytes?

When osteoblasts get trapped within the calcified matrix, their structure and function changes; they become osteocytes. Osteoclasts develop from monocytes and macrophages and differ in appearance from other bone cells.

How do you remember the difference between osteoblasts and osteoclasts?

My mnemonic for remembering osteoblasts and osteoclasts: We have a Blast making stuff with osteoBlasts! If I can remember just one of the two, I’ll know the other one – osteoclast – breaks bone down.

Does an osteoblast become an Osteocyte?

During osteogenesis, osteoblasts lay down osteoid and transform into osteocytes embedded in mineralized bone matrix. Despite the fact that osteocytes are the most abundant cellular component of bone, little is known about the process of osteoblast-to-osteocyte transformation.

What is the function of an Osteocyte?

The potential functions of osteocytes include: to respond to mechanical strain and to send signals of bone formation or bone resorption to the bone surface, to modify their microenvironment, and to regulate both local and systemic mineral homeostasis.

What are the similarities and differences between osteocytes osteoblasts and osteoclasts?

Similarities between Osteoblasts and Osteoclasts

Sl. No. Osteoblasts Osteoclasts
11 Osteoblasts are not equipped with phagocytic-like mechanism. Osteoclasts are equipped with phagocytic-like mechanism.
12 Osteoblasts become osteocytes at the end of the bone formation. Osteoclasts do not become osteocytes.

What is inside an Osteocyte?

Osteocyte, a cell that lies within the substance of fully formed bone. It occupies a small chamber called a lacuna, which is contained in the calcified matrix of bone. Osteocytes derive from osteoblasts, or bone-forming cells, and are essentially osteoblasts surrounded by the products they secreted.

What type of cell is an Osteocyte?

What’s the difference between osteoblasts and osteoclasts?

Osteoblasts, Osteocytes, and Osteoclasts. Osteocytes are cells that form the bones themselves, osteoblasts are responsible for the formation of new osteocytes, whereas osteoclasts are responsible for the resorption of old bone matter.

How big is the nucleus of an osteocyte?

Osteocytes are a type of bone cells present inside the mature bones. They are star-shaped cells with projections. The size of a cell body of an osteocyte may vary from 5-20 micrometers in diameter. A mature osteocyte consists of a single nucleus.

When do osteocytes become part of the bone?

Osteocytes are formed from osteoblasts, and become part of the bone (and, as discussed above, ‘become’ osteocytes) when they mature. They send out long tendrils (as seen in the figure) which connect numerous osteocytes to each other. They produce bone matrix, including collagen and calcium/phosphorus compounds, that eventually covers them.

How does the osteoclast help heal the bone?

Osteocytes maintain bone mass, and are also speculated to act as the command centers of the bones when experiencing stress, using their connection with other osteocytes. The osteocytes direct osteoclasts to the site of the damage, hastening healing.
