blood vessels. Internal bone surfaces are covered with a delicate connective tissue membrane called the endosteum . The endosteum covers the trabeculae of spongy bone and lines the canals that pass through the compact bone. It also contains both osteoblasts and osteoclasts.
Between the epiphysis and diaphysis epiphyseal plate or growth plate is present. XI Std Biology-Zoology Chapter- Table: .
