What are the small channels that radiate from lacunae and transport nutrients and signals between osteocytes?

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

Answer: (C)

Canaliculi are the tiny channels that radiate from lacunae, forming a network that connects osteocytes. Through these channels, osteocytes extend processes and share nutrients and signaling molecules via diffusion and gap junctions, coordinating bone maintenance and remodeling. Lacunae are the small cavities that house osteocytes; osteocytes are the bone cells; trabeculae are the lattice-like structures of cancellous bone. So the small channels described are canaliculi.
