A network of tubules that runs through compact bone is called the
- A
Haversian canal
- B
Periosteum
- C
Marrow
- D
Joint
The correct answer is the Haversian canal. These canals are part of the microscopic structure of compact bone and facilitate the transportation of blood vessels and nerve fibers throughout the dense bone structure, communicating with osteocytes. The other options are not networks of tubules: the periosteum is a tissue layer on bones, marrow is the soft tissue inside bones, and a joint is where bones connect, allowing for movement.
Haversian canals are a series of tubes within compact bone that contain blood vessels and nerves, crucial for nutrient and oxygen supply to bone cells.
The periosteum is a dense layer of vascular connective tissue enveloping the bones except at the surfaces of the joints; it is not a network of tubules.
Bone marrow is the soft tissue found in the hollow interior of bones, responsible for blood cell production, not a tubule network.
A joint is the location at which two or more bones make contact; it is involved in movement, not a network of tubules.
