Skeletal System
The complex framework of bones, joints, and connective tissues that provides structural support, enables movement, and distributes forces throughout the body of vertebrates.
Skeletal System
The skeletal system represents one of nature's most sophisticated examples of Force Distribution engineering, evolved over millions of years to provide optimal support and protection for living organisms.
Core Functions
The skeletal system serves multiple critical purposes:
- Structural Support
- Maintains body shape and posture
- Provides attachment points for Muscular System
- Creates a framework for internal organs
- Force Management
- Distributes Body Weight across multiple points
- Absorbs and dissipates Impact Forces
- Enables efficient Locomotion movement
- Protection
- Shields vital organs
- Houses Bone Marrow for blood cell production
- Protects the Central Nervous System
Anatomical Components
Bones
The adult human skeleton contains 206 bones, categorized as:
- Long bones (e.g., femur, humerus)
- Short bones (e.g., carpals, tarsals)
- Flat bones (e.g., skull, scapula)
- Irregular bones (e.g., vertebrae)
- Sesamoid Bones
Joints
Joints enable movement and force transfer through:
- Synovial Joints (mobile connections)
- Fibrous Joints (immobile connections)
- Cartilaginous Joints connections
Connective Tissues
Essential supporting structures include:
