Channels that enable communication between osteocytes within bone matrix are called?

• A. Lacunae
• B. Lamellae
• C. Trabeculae
• D. Canaliculi

Answer: (D)

Osteocytes in bone communicate through tiny channels called canaliculi that form a network within the mineralized matrix. These channels extend from lacunae—the small spaces that house osteocytes—and connect to neighboring osteocytes via slender cell extensions and gap junctions. This canalicular network lets nutrients, wastes, and signaling molecules diffuse efficiently through the dense bone, enabling cells to coordinate responses to mechanical load and maintain bone tissue. Lacunae are the little houses for osteocytes, lamellae are the layered rings of the bone matrix, and trabeculae are the beam-like structures of cancellous bone; none of these are the communication channels themselves. So canaliculi are the channels that enable osteocyte communication within bone.
