Multiple Choice
Which of the following is something that chondrocytes and osteocytes have in common?
A
Both are found in the periosteum.
B
Both are responsible for the mineralization of bone.
C
Both are involved in the production of collagen fibers.
D
Both reside in lacunae.
Verified step by step guidance
1
Begin by understanding the roles of chondrocytes and osteocytes. Chondrocytes are the cells found in cartilage, while osteocytes are the cells found in bone tissue.
Recognize that both chondrocytes and osteocytes reside in small cavities within their respective tissues. These cavities are known as lacunae.
Consider the structure of cartilage and bone. In cartilage, chondrocytes are embedded within the matrix in spaces called lacunae. Similarly, in bone, osteocytes are housed in lacunae within the mineralized matrix.
Evaluate the other options provided in the problem. Chondrocytes are not found in the periosteum, nor are they responsible for bone mineralization. Osteocytes do not produce collagen fibers; this is primarily the role of osteoblasts.
Conclude that the commonality between chondrocytes and osteocytes is their residence in lacunae, which is a characteristic feature of both cell types in their respective tissues.
