Skeletal System
Bones, joints, cartilage, and connective tissue
System Overview
Function & Structure
The skeletal system provides structural support and enables movement through 206 bones in adults. Components include:
Bone Tissue
- Compact bone: Dense outer layer providing strength
- Spongy bone: Inner trabecular structure with bone marrow
- Periosteum: Outer membrane containing blood vessels and nerves
- Endosteum: Inner membrane lining bone cavities
Joint Classifications
- Synovial joints: Freely movable with synovial fluid
- Cartilaginous joints: Slightly movable with cartilage connection
- Fibrous joints: Immovable with fibrous tissue connection
- Ligaments: Connect bone to bone for stability
Bone Composition
- Collagen matrix: Provides flexibility and tensile strength
- Hydroxyapatite: Calcium phosphate crystals for hardness
- Bone cells: Osteoblasts, osteoclasts, and osteocytes
- Bone marrow: Red marrow for blood production, yellow for fat storage
Key Functions
Structural Support
- Body framework and shape maintenance
- Organ protection (skull, ribcage, pelvis)
- Weight-bearing capacity for upright posture
- Attachment points for muscles and ligaments
Movement Facilitation
- Lever system for muscle force amplification
- Joint mobility and range of motion
- Shock absorption during impact activities
- Balance and coordination support
Metabolic Functions
- Calcium and phosphate storage and release
- Blood cell production in bone marrow
- Fat storage in yellow bone marrow
- Hormone production (osteocalcin, FGF23)
Common Health Concerns
Bone Density Issues
- Osteoporosis and increased fracture risk
- Osteopenia (low bone density)
- Age-related bone loss
- Hormonal influences on bone health
Joint Problems
- Arthritis and joint inflammation
- Cartilage degeneration and wear
- Joint stiffness and reduced mobility
- Sports-related joint injuries
Bone Health Factors
- Inadequate calcium and vitamin D intake
- Sedentary lifestyle and lack of weight-bearing exercise
- Hormonal changes affecting bone metabolism
- Medications that impact bone density
Supplement Support
Bone Building Nutrients
- Calcium for bone mineral density
- Vitamin D3 for calcium absorption
- Vitamin K2 for bone protein activation
- Magnesium for bone formation
Bone Matrix Support
- Collagen peptides for bone protein structure
- Vitamin C for collagen synthesis
- Silicon for connective tissue strength
- Boron for calcium and magnesium utilization
Joint Health
- Glucosamine for cartilage synthesis
- Chondroitin for cartilage hydration
- MSM for joint comfort and flexibility
- Hyaluronic acid for joint lubrication
Lifestyle Factors
Bone Health Habits
- Weight-bearing and resistance exercise
- Impact activities for bone stimulation
- Adequate sun exposure for vitamin D
- Avoiding smoking and excessive alcohol
- Maintaining healthy body weight
Dietary Considerations
- Calcium-rich foods (dairy, leafy greens, sardines)
- Vitamin K sources (dark leafy greens)
- Protein for bone matrix formation
- Limiting sodium and caffeine excess
- Adequate overall nutrition for bone building
Key Functions
Provides structure, protects organs, enables movement, produces blood cells, stores minerals
Common Health Issues
Bone loss, joint pain, arthritis, fractures, osteoporosis, cartilage wear
