bone, trabecular

Quick Reference

The spongy bone, consisting of a structural mesh of trabeculae forming an internal scaffold, found mainly at the ends of long bones, in vertebral bodies, and flat bones, accounting for some 20% of total body bone. The spaces between the trabeculae are filled with red and yellow marrow (see bone marrow). Although only 20% of total bone in the body, it accounts for most of bone turnover because it has a larger surface area than cortical bone (see bone, cortical).
