The Structural Units of Mature Compact Bone are Called

Question

The structural units of mature compact bone are called
A) trabeculae.
B) osteocytes.
C) osteons.
D) canaliculi.
E) lamellae.

Accepted Answer

The structural units of mature compact bone are called osteons, which consist of concentric rings of lamellae surrounding a central canal called the Haversian canal. The lamellae contain collagen fibers and mineralized matrix, and are arranged in alternating directions to provide strength to the bone. Osteocytes, canaliculi, and trabeculae are all components of bone tissue, but are not the structural units of compact bone.
