The periosteum covering bone is best described as which type of connective tissue?

The periosteum covering bone is best described as which type of connective tissue?

• A. Periosteum-Loose (areolar) connective tissue
• B. Periosteum-Dense irregular connective tissue
• C. Endosteum-Dense irregular Connective tissue
• D. Periosteum-Elastic connective tissue

Answer: (B)

The periosteum is a fibrous covering around bone, and its outer layer is made of dense irregular connective tissue. This tissue type has collagen fibers arranged in multiple directions, which helps the periosteum resist stresses from different angles and provides a strong, protective envelope for the bone. While the inner layer of the periosteum is more cellular (osteogenic), the overall description most associated with the periosteum’s connective tissue is dense irregular connective tissue. By contrast, the endosteum lines the inner bone surfaces and is not dense irregular connective tissue, and elastic connective tissue isn’t the typical tissue found in the periosteum.
