What Is the Axial Skeleton?
The axial skeleton is the central framework of the human body. It consists of 80 bones that form the head, neck, and trunk, including the skull, vertebral column (spine), ribs, sternum (breastbone), and hyoid bone. Together, these bones support the body’s structure and protect vital organs such as the brain, spinal cord, heart, and lungs.
The axial skeleton works together with the appendicular skeleton, which includes the bones of the arms, legs, shoulders, and pelvis, to allow movement and maintain posture.
Why the Axial Skeleton Matters
The axial skeleton provides support, protects major organs, and serves as an attachment point for muscles that control posture, breathing, and movement.
Bones of the Axial Skeleton
- Skull
- Vertebral column (cervical, thoracic, lumbar spine, sacrum, and coccyx)
- Ribs
- Sternum (breastbone)
- Hyoid bone
Common Conditions Affecting the Axial Skeleton
- Osteoporosis
- Spinal fractures
- Scoliosis
- Degenerative disc disease
- Arthritis of the spine
- Spinal stenosis
How Are Axial Skeleton Conditions Diagnosed?
Healthcare providers diagnose disorders of the axial skeleton through a physical examination, X-rays, CT scans, MRI, bone density testing, and other imaging studies depending on the suspected condition.
How Are Axial Skeleton Conditions Treated?
Treatment varies depending on the condition and may include medications, physical therapy, exercise, bracing, pain management, or surgery in more severe cases.
How Home Care Can Help
Home care professionals assist with mobility, fall prevention, medication reminders, rehabilitation exercises, daily activities, and creating a safer home environment for individuals with spinal or skeletal conditions.
Home Care Tip
Maintaining good posture, staying physically active, and consuming enough calcium and vitamin D can help support long-term bone health.
Frequently Asked Questions About the Axial Skeleton
How many bones are in the axial skeleton?
The axial skeleton consists of 80 bones that form the body’s central framework.
What is the difference between the axial and appendicular skeleton?
The axial skeleton includes the head, neck, and trunk, while the appendicular skeleton includes the bones of the arms, legs, shoulders, and pelvis.
