- Lamellar bone
- Microscopically dense parallel arrays of bone.
- Membranous ossification
- The process of bone formation in which bone is directly laid in apposition on top of the bone that has just formed.
- Modeling
- The process that is responsible for changing the size and shape of bony tissue.
- Osteoblasts
- Mesenchymal cells that contribute to bone production and can be seen lining bone surfaces.
- Osteocytes
- Smaller elongated cells contained within small cavities in bone called lacunae
- Osteoclasts
- Hematopoietic derived, multinucleated cells that resorb bone.
- Osteons
- A tubular functional unit of lamellar cortical bone.
- Remodeling
- The process that is responsible for bony tissue maintenance.
