What is epiosteum?

Answer 1

While most tissues have a Endo, Peri, and Epi covering. Bone simply has an endosteum and periosteum. Some older texts will refer to the periosteum as an epiosteum. The periosteum is found enveloping bones with the exception of the articulating joints. The periosteum contains a fibrous outer layer and a cellular inner layer containing progenitor cells.
