What are the membranes that cover bones and what are their functions?
- 1. Periosteum: wraps around the outside of the bone, has a fibrous superficial layer and a cellular deep layer, isolates bone from surrounding tissues, provides route for nervous and circulatory supply, participates in bone regrowth and repair
- 2. Endosteum: Incomplete cellular layer that lines the medullary cavity of the bone, consists of a simple flattened layer of osteoprogenitor cells
