Question

Haversian canals of long bones have

• A. One vein and one artery
• B. One nerve and one lymphatic
• C. Some bone cells, fat and areolar tissue
• D. All of the above

Answer 1

Answer: (D)

All of the above

The Haversian canal is the central canal in the middle of the compact bone. Each canal of the bone contains one or two blood vessels, with a small quantity of delicate connective tissue and some nerve filament. In the larger bones, there are also lymphatic vessels, and cells with branching processes, which communicate through the canaliculi with the branched processes of certain bone cells in the substance of the bone.
Thus, the correct answer is the option D.
