bone (osseus) tissue
Catilage
In lacunae, you can find chondrocytes. Chondrocytes are cells that are responsible for maintaining the extracellular matrix of cartilage tissue.
Lacunae are small spaces found within certain types of tissue, such as bone and cartilage. In bone tissue, lacunae contain osteocytes, which are mature bone cells that maintain the bone matrix. In cartilage, lacunae house chondrocytes, the cells responsible for producing and maintaining the cartilage matrix. These cells play crucial roles in the health and maintenance of their respective tissues.
In biological terms, lacunae can refer to the small cavities within bone tissue where osteocytes reside. In a general sense, lacunae can also refer to any small empty space or gap within a structure.
When chondrocytes in lacunae divide and form new matrix, it leads to an expansion of the cartilage tissue from within. What is this process called?
Cells in lacunae allow for the exchange of nutrients and waste products with the surrounding extracellular matrix. They also help maintain tissue structure and function by secreting and maintaining the matrix components.
Osseous tissue
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.
The canal that connects lacunae to osteocytes is called a canaliculus. Canaliculi are small channels that allow for communication and nutrient exchange between osteocytes located within lacunae in compact bone tissue.
