Question

Quizplus · Accepted Answer

The main portion of the periodontal ligament is composed of bundles of white collagenous connective tissue fibers, which are bundled together like the many strands of a rope. Osseous trabeculae are NOT part of the periodontal ligament but are an integral part of the architectural arrangement of the bone. Osseous is a term descriptive of bone.
