Shares & Saves. Save. Bone spicule is a term found in osteology, in dental surgery and also in ophthalmology. It is most commonly used to define the bony matrix in the formation of new bone but is also used to describe a complication in dental surgery and a symptom of an eye disease.(Andreas Rodriguez/iStock/Getty Images).he formation of new bone begins with the development of a bony matrix made up of bone spicules. These spicules are made up of networks of thin fibers with calcified deposits interwoven throughout. The fibers calcify and enclose some osteoblasts (bone-making cells) and begin to form new bone spicules.
Spongy (Cancellous) Bone. Spongy (cancellous) bone is lighter and less dense than compact bone. Spongy bone consists of plates (trabeculae) and bars of bone adjacent to small, irregular cavities that contain red bone marrow.The canaliculi connect to the adjacent cavities, instead of a central haversian canal, to receive their blood supply.ompact bone consists of closely packed osteons or haversian systems. The osteon consists of a central canal called the osteonic (haversian) canal, which is surrounded by concentric rings (lamellae) of matrix. Between the rings of matrix, the bone cells (osteocytes) are located in spaces called lacunae.
