What does Osteocytes secrete?
Osteocytes become surrounded by bone matrix and are relatively inactive, but do have the capability to produce components needed to maintain the bone matrix if needed. Lacunae osteoblasts change into osteocytes.
What tissue has chondrocytes and osteocytes?
Cartilage tissue has chondrocytes, which are responsible for synthesizing and maintaining the extracellular matrix of the cartilage. Bone tissue has osteocytes, which are mature bone cells embedded in the mineralized matrix and play a role in bone remodeling and maintenance.
Do osteocytes become osteoblasts when they are completely surrounded by bony matrix?
As you know, osteoblasts secrete collagen and organic cmpounds upon which bone is formed. Osteoblasts are incapable of mitosis. As Osteoblasts release matrix materials around themselves, they become enveloped by the matrix and at this point differentiate into Osteocytes.
What type of tissue is replaced in the embryo during endochondral ossification?
During endochondral ossification, the hyaline cartilage model in the embryo is gradually replaced by bone tissue. Osteoblasts deposit bone matrix around the cartilage model, which is then mineralized and eventually becomes mature bone tissue.
How does the bone replace the cartilage in the body?
Bone does not usually replace cartilage in the body. Instead, cartilage can be converted into bone during a process called endochondral ossification, which is essential for bone growth and development. This process involves the gradual replacement of cartilage with bone tissue.
Does Endochondral ossification occurs when chondrocytes replace osteoblasts in the matrix.?
No, you have it backwards. "Chondro" is the prefix for cartilage while "osteo" is the prefix for bone. Endochondral ossificiation is when the cartilage is replaced by bone, so you would have osteocytes moving into the matrix and replacing the chondrocytes.
What are bone cells found in the lacunae within the matrix called?
Bone cells found in the lacunae within the matrix are called osteocytes. They are responsible for maintaining the bone structure and communicating with other bone cells to regulate bone remodeling and repair.

What are the cells of the bone?
They're called OSTEOCYTES calcifying together in a matrix tissue of bone matter.

Which bone contains osteocytes and lacunae?
Osteocytes and lacunae are found in the mineralized extracellular matrix of bone tissue, not within a specific bone. Osteocytes are the primary cells of mature bone, residing within small cavities called lacunae.
What are the cells that produce organic matrix in bone?
The cells that produce the collagen and inorganic salts of bone matrix are osteocytes. Osteocytes maintain the protein and mineral content of the bone matrix. Osteogenesis is the production of new bone matrix.
Osteocytes pass nutrients and wastes back and forth in passageways in the matrix called?
Osteocytes pass nutrients and wastes through canaliculi, which are thin channels in the bone matrix. These canaliculi connect neighboring osteocytes and allow for communication and exchange of substances within the bone tissue.
What Bone cells maintain the mineral content of bone?
Osteoblasts are bone cells responsible for building and maintaining the mineral content of bone. They help produce new bone tissue and regulate the deposition of minerals like calcium and phosphate.
