part of part of conduit for blood vessel anatomical conduit bone foramen osteon haversian canal Haversian canals are a series of tubes around narrow channels formed by lamellae. This is the region of bone called compact bone. Osteons are arranged in parallel to the long axis of the bone. The Haversian canals surround blood vessels and nerve cells throughout the bone and communicate with osteocytes in lacunae (spaces within the dense bone matrix that contain the living bone cells) through canaliculi. This unique arrangement is conducive to mineral salt deposits and storage which gives bone tissue its strength. haversian canals FMA:224787 UBERON:0014731 Wikipedia:Haversian_canal nutrient canal NCIT:C32713 SCTID:3336003
