What is Axial and Appendicular Skeleton?
The human skeleton is divided into two main parts: the axial skeleton and the appendicular skeleton.
Axial Skeleton:
The axial skeleton forms the central axis of the body and includes the following bones:
- Skull
- Vertebral column (spine)
- Rib cage (thoracic cage)
Appendicular Skeleton:
The appendicular skeleton comprises the bones of the limbs and their associated girdles:
- Pectoral girdle (shoulder bones)
- Upper limbs (arms, forearms, hands)
- Pelvic girdle (hip bones)
- Lower limbs (thighs, legs, feet)
Functional Differences:
- Axial skeleton: Protects vital organs, provides posture and flexibility.
- Appendicular skeleton: Enables movement and locomotion.
Clinical Significance:
- Injuries and disorders of the axial skeleton can affect mobility, stability, and organ function.
- Appendicular skeleton injuries can cause pain, immobility, and functional impairments.
