Findings

At higher power, the growth (epiphyseal) plate is evident above the calcified cartilage trabeculae and bone marrow. Note that the perichondrium and periosteum separate the developing bone from surrounding connective tissue.

Comment

Calcified cartilage trabeculae will ultimately be reabsorbed before bone is laid down by osteoblasts.
