Which of the following is a key histological difference between the periosteum and the endosteum during growth?
Show answer and explanation
Correct answer: The periosteum is bilayered, while the endosteum is a single cell layer.
The periosteum is a double-layered membrane with an outer fibrous layer and an inner osteogenic layer. The endosteum is much thinner, consisting of a sparse layer of osteoprogenitor cells and osteoblasts lining the internal surfaces.
