Which structure corresponds to canaliculi in compact bone?

• A. Canaliculi of compact bone
• B. Canaliculi of hyaline cartilage
• C. Canaliculi of spongy bone
• D. Canaliculi of trabeculae bone

Answer: (A)

Canaliculi are tiny channels that connect osteocytes housed in lacunae, forming a network that lets cellular extensions communicate and nutrients diffuse through the mineralized bone matrix. In compact bone, these channels thread through the concentric lamellae of an osteon, linking lacunae to each other and to the vascular supply so the bone cells stay nourished and coordinated. The best answer names these channels within the tissue itself: canaliculi of compact bone. Hyaline cartilage doesn’t form a canalicular network like bone does, so that choice isn’t fitting. While canaliculi exist in other bone forms as well, the precise phrase that identifies the channels in the compact bone context is canaliculi of compact bone.
