Question

All are found in spongy bones except

• A. Osteoblast
• B. Bone marrow
• C. Lacunae and canaliculae
• D. Haversian canal

Answer 1

The correct option is D Haversian canal

Haversian canals are a series of microscopic tubes in the outermost region of bone called cortical bone that allows blood vessels and nerves to travel through them.

Spongy bone is a network of irregularly-shaped sheets and spikes of bone (trabeculae). The trabeculae are only a few cell layers thick. The spaces between the trabeculae contain red or yellow marrow, depending on a person's age and on which bone it is. It consists of osteoblast, bone marrow, lacunae and canaliculae.

So, the correct answer is option D.
