Examples of trabecula in the following topics:
-
- The first step in the process is the formation of bone spicules (aggregates of bony matrix) that eventually fuse with each other and become trabeculae.
- The periosteum is formed and bone growth continues at the surface of trabeculae.
- Much like spicules, the increasing growth of trabeculae result in interconnection, and this network is called woven bone.
- As growth continues, trabeculae become interconnected and woven bone is formed.
-
- Osteoblasts add layers of fresh bone to the trabeculae.
- Osteoblasts, differentiated from the osteoprogenitor cells that entered the cavity via the periosteal bud, use the calcified matrix as a scaffold and begin to secrete osteoid, which forms the bone trabecula.
-
-
- The internal architecture of the trabeculae undergoes adaptive changes, followed by secondary changes to the external cortical portion of the bone, perhaps becoming thicker as a result.
-
- In the region of the brain, particularly, a large number of fine filaments called arachnoid trabeculae pass from the arachnoid through the subarachnoid space to blend with the tissue of the pia mater.
