Lacunae - Correct Answers -small spaces between the lamellae which contain
osteocytes
Osteocytes - Correct Answers -a bone cell, formed when an osteoblast becomes
embedded in the matrix it has secreted. Mature bone cells

the bones except at the surfaces of the joints.
articular cartilage - Correct Answers -covers the surfaces of bones where they come
together to form joints
