Q

What is pictured? Differentiate between Ob and Oc and tell why they are located where they are

A

Q

What is pictured? What is the top layer that has Ob in it? What is the bottom layer? Who is Oc?

A

This is active periosteum. The active periosteim is in the top layer and has osteoblasts and collagen fibers present

The lower layer is newly formed bone with Osteocytes (Oc) that are becoming trapped
