Study Notes
Bone Structure and Types
- Endosteum: Membrane lining the inside of bone cavities.
- Compact Bone: Dense and smooth bone comprising two thin plates, typically found in flat bones.
- Irregular Bones: Bones with atypical shapes, such as vertebrae.
- Diaphysis: The shaft of a long bone.
- Articular Cartilage: Cushions the ends of long bones and absorbs stress.
- Epiphysis: The ends of long bones.
- Short Bones: Cube-shaped bones located in the wrist and ankles.
- Periosteum: Membrane that covers and protects the exterior of bones.
- Diploe: Spongy bone located inside flat bones.
Bone Growth and Development
- Epiphyseal Lines: Represent the "growth plate" of long bones.
- Lamella: Collagen-based matrix tubes that bear weight and surround canals.
- Volkmann's Canal: Canals perpendicular to central canals that carry blood vessels and nerves.
- Appositional Bone Growth: Increase in bone thickness and diameter.
- Intramembranous Ossification: Bone development from a fibrous membrane.
- Longitudinal Bone Growth: Conversion of hyaline cartilage to bone at the epiphyseal growth plate for elongation.
Bone Cells and Composition
- Canaliculi: Hair-like canals connecting lacunae and transporting bone material.
- Hydroxyapatites: Inorganic salts that constitute 65% of bone mass, crucial for hardness and compression resistance.
- Osteoclasts: Cells involved in bone resorption and appositional growth.
- Osteocytes: Mature bone cells housed in small cavities called lacunae.
- Lacunae: Small cavities in bone containing osteocytes.
Bone Fractures
- Depressed Fracture: Bone portion displaced inward, typical in skull injuries.
- Greenstick Fracture: Incomplete break; one side breaks while the other bends, common in children.
- Displaced Fracture: Bone ends misaligned after a fracture.
- Simple (Closed) Fracture: Bone fracture where skin remains intact.
- Spiral Fracture: Ragged break due to excessive twisting, often seen in sports injuries.
- Complete Fracture: Bone break extending completely through the bone.
- Comminuted Fracture: Bone shattered into three or more pieces, often seen in older adults.
- Compound Fracture: Fracture where bone penetrates the skin.
Bone Density and Health
- Epiphyseal Line: Area containing the growth plate in bones.
- Bone Marrow: Soft tissue found between trabeculae within the bone.
- Yellow Bone Marrow: Fatty tissue contained in the medullary cavity.
- Paget's Disease: Common bone disease affecting the elderly characterized by abnormal bone remodeling.
- Nondisplaced Fracture: Fracture where bone ends remain aligned.
