Which statements characterize endosteum?
☐ It is active during bone repair
☐ It covers the diaphysis of a bone
☐ It lines medullary cavities
☐ It contains osteoblasts
Answer (2)
The endosteum is essential in bone repair, lines the medullary cavities, and contains osteoblasts. It does not cover the diaphysis, which is instead covered by the periosteum. Understanding these characteristics helps clarify the role of endosteum in bone physiology. ;
The endosteum is active during bone repair, lines medullary cavities, and contains osteoblasts, which are essential for bone health and repair. However, it does not cover the diaphysis, that area is covered by the periosteum. Thus, the correct statements about the endosteum are the first three options listed in the question.
