Elastic Cartilage Chondrocyte: cartilage cell Lacunae: Small spaces between adjacent concentric lamellae that house osteocytes. This canal that runs through the osteon is called the Haversian canal. Small blood vessels that are present in the central canal perform the function of supplying blood to the osteocytes. Each osteon is composed of concentric rings of calcified matrix called lamellae (singular = lamella). Question: QUESTION 2 Blood Vessels And Nerves Run Length-wise Through Bone In The Center Of An Osteon, Called The Canal. Many lamellae will make up an osteon and many osteons will make up the compact bone. So those are the concentric layers of calcified tissue. This canal that runs through the osteon is called the Haversian canal. A haversian canal is a central canal within the haversian system — a network of canals inside compact bone.Haversian canals occur in the center of compact bone and contain blood vessels, connective tissues, nerve fibers and lymphatic vessels.Osteons, or the structure that forms compact bone, surround these canals and are the outer component of the haversian system. Answer and Explanation: The canal that runs through the core of each osteon contains (d) nerve fibers and blood vessels. Expert Answer . What canal runs down the center of each osteon?
