Download Bone Ossification Zones Images. Ossification, or bone formation, begins with a framework that consists of either mesenchymal the process proceeds in the direction of both epiphyses → two progressive ossification zones. Ossification (or osteogenesis) in bone remodeling is the process of laying down new bone material by cells called osteoblasts.

Bone comprises the structure of the skeletal system and provides lever arms for locomotion. The walls between the lacunae break down and the chondrocytes die. Endochondral ossification is the other majory embryonic process of bone formation.

Frontal bone at birth the frontal bone is ossified in membrane ossification — bone is broken down by osteoclasts, and rebuilt by osteoblasts, both of.

• resting zone • zone of proliferation • zone of hypertrophy • zone. Bones grow in length at the epiphyseal plate by a process that is similar to endochondral ossification. The proliferative zone is the next layer toward the diaphysis and contains stacks of slightly larger chondrocytes. • resting zone • zone of proliferation • zone of hypertrophy • zone.
