What are the Extracellular Fluid Filled Extensions of the Lacunae

Question

What are the extracellular fluid filled extensions of the lacunae called?
A)interosteonic (perforating)canals
B)osteonic (Haversian)canals
C)concentric lamellae
D)canaliculi
E)perforating (Sharpey's)fibers

Accepted Answer

The extracellular fluid filled extensions of the lacunae are called canaliculi. Interosteonic (perforating) canals connect adjacent osteons, osteonic (Haversian) canals run through the center of each osteon, concentric lamellae are the layers of bone tissue surrounding the osteonic canals, and perforating (Sharpey's) fibers connect tendons and ligaments to bone.
