Study Notes
Epiphyseal vs. Diaphyseal Faces of the Epiphyseal Plate
- Epiphyseal face contains cartilage cells that continue to grow and divide through mitosis.
- Diaphyseal face is characterized by aging and dying cartilage cells, followed by the activity of osteoblasts that form new bone.
Function of Organic Matrix in Bone
- The organic matrix provides flexibility and strength, making bones resilient to stress.
Important Organic Bone Composition
- Collagen fibers play a crucial role in maintaining the structural integrity of bones.
- Osteocytes, mature bone cells, are embedded within the bone matrix and are vital for bone maintenance and health.
Role of Calcium Salts in Bone
- Calcium salts constitute the majority of the inorganic material in bone.
- They are essential for imparting hardness and compressional strength to the bone, enabling it to withstand various forces.
Effects of Baking Bone
- Baking bone removes the organic components, which reduce its flexibility and strength, resulting in a brittle structure.
Effects of Soaking Bone in Acid
- Soaking bone in acid extracts the minerals, leading to loss of hardness and structural integrity, making the bone more pliable.
