The cells of which of the following are enclosed in small cavities within the matrix?

The cells of cartilage and bone are enclosed in small cavities within the matrix.

In cartilage, the cells, called chondrocytes, are housed within small spaces called lacunae within the extracellular matrix. Similarly, in bone tissue, the bone cells, called osteocytes, reside within small cavities known as lacunae within the mineralised matrix of bone. These lacunae provide a protected environment for the cells and allow for communication and nutrient exchange between neighboring cells and the surrounding tissue.
