The site of such a cluster is called a centre of ossification. Definition. Spongy bone is found at the epiphyses (ends) of the long bones and at the center of other bones. They do contain lamellae, or layers of bone matrix, but the lamellae are parallel to each other. Bone's mineral phase – calcium hydroxyapatite, Ca 10 (PO 4) 6 (OH) 2 – is subdivided into a mosaic of tiny microcrystallites, thereby creating a large surface area for ion exchange and limiting the spread of cracks. Each osteon is composed of concentric rings of calcified matrix called lamellae (singular = lamella). An osteon is also called a Haversian system. D) ossification. The Lacunae are situated between the lamellae and consist of a number of oblong spaces. Later calcium & other minerals are deposited and tissue calcifies 34.
