MICROANATOMY

Detailed explanation-1: -Haversian canals (sometimes canals of Havers) are a series of microscopic tubes in the outermost region of bone called cortical bone. They allow blood vessels and nerves to travel through them to supply the osteocytes. Diagram of compact bone from a transverse section of a typical long bone’s cortex.

Detailed explanation-2: -A central Haversian canal penetrates the osteon and serves as a passage for blood cells, lymph vessels, and nerves.

Detailed explanation-3: -Every Haversian canal contains a vein, artery, a lymph vessel, some bone cells and nerve, all packed in with connective tissue. Blood vessels and nerves-Haversian canals contain blood vessels, lymphatic vessels and nerves.

Detailed explanation-4: -Haversian canals contain blood vessels only. Haversian canals contain blood vessels and nerve fibers. Spongy tissue is found on the interior of the bone, and compact bone tissue is found on the exterior.

Detailed explanation-5: -Haversian canal and Volkmann’s canal are two types of canals found in compact bones. Both allow blood vessels and nerve fibres to travel through them. Volkmann’s canals interconnect Haversian canals with each other and with the outer covering of the bone. Both types of canals provide nourishment to the osteons.
