Distinguishing Between Axial and Appendicular Skeleton Functions
Let's break down these two major divisions of our skeleton and understand what makes them uniquely suited for their specific roles!
Axial Skeleton: The Core Framework
The axial skeleton forms the central axis of our body and includes 80 bones:
Skull
Vertebral column (spine)
Ribs
Sternum (breastbone)
Primary Functions of the Axial Skeleton
Protection of Vital Organs
Brain protection by the skull
Heart and lung protection by the rib cage
Spinal cord protection by the vertebral column
Support and Stability
Provides central framework for body posture
Acts as attachment points for muscles
Maintains upright position
Note
The axial skeleton is like the "core" of your body's structural system - everything else builds from here!
Appendicular Skeleton: The Movement Specialist
The appendicular skeleton consists of 126 bones:
Upper limbs (arms)
