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.
2.2 The Structure of Spongy Bone Spongy Bone does not include osteons (the basic unit/s of Compact Bone-see above). Instead, spongy bone consists of an irregular lattice of thin columns of bone called trabeculae (literally little beams), which contain lamellae, osteocytes, lacunae and canaliculi.he basic unit of Compact Bone is an  osteon , which is also known as a  Haversian System . Each Haversian System (unit) has a cylindrical structure that consists of four parts: 1  A central tube called a Haversian Canal, which contains blood vessels and nerves. 2  The Haversian Canal is surrounded by alternate layers of:
