The space in the matrix of cartilage that contains a chondrocyte is called a "lacuna."

Lacunae are small cavities or spaces within the cartilage matrix where chondrocytes, the cells responsible for maintaining cartilage, reside. These structures are crucial for the health and functionality of cartilage. Each lacuna usually houses one or two chondrocytes that are embedded in the extracellular matrix, which consists of collagen fibers, proteoglycans, and water. The lacunae provide a protective environment for the chondrocytes, facilitating nutrient exchange and waste removal through the surrounding matrix. This organization is essential for the maintenance of cartilage's structural integrity and its ability to withstand compressive forces in joints.
