How is the cartilage similar to bones?
They both have a mineralized extracellular matrix.
They both exhibit rigidity as connective tissues.
They both contain cells within small spaces.
They both contribute to the formation of the bone marrow.
Cartilage and bones are similar in the aspect that they both contain cells within small spaces. In cartilage, the cells called chondrocytes are found within cavities called lacunae. Similarly, in bones, the cells, known as osteocytes are housed within spaces called lacunae as well. These spaces within the extracellular matrix of cartilage and bone allow the cells to reside and perform their functions. The presence of cells within small spaces is essential for maintaining the structure and integrity of both cartilage and bone tissues. Therefore, option 3 is the correct answer.
