Bone matrix: remodeling (spongy bone)
These images illustrate the progression of woven to lamellar bone in spicules of spongy bone. 400x
Woven, spongy bone >
The matrix of this spicule consists of woven bone, which is not organized into lamellae, osteocyte lacunae are numerous and rounded, and the matrix stains faintly bluish.
Woven to lamellar >
The matrix of this spicule is in the process of being remodeled from woven into lamellar bone.
- Woven
The matrix of this spicule is in the process of being remodeled from woven into lamellar bone.
- Lamellar
The matrix of this spicule is in the process of being remodeled from woven into lamellar bone.
Lamellar, spongy bone >
The matrix of this spicule has been completely remodeled into lamellar bone, consisting of flattened plates with an orderly arrangement of the osteocytes.
Osteocytes >
Osteocytes in areas of woven bone appear larger and more randomly arranged than in lamellar bone.
Osteoblasts >
Osteoblasts are depositing osteoid on the surface of the spicule.
