HBS109 Week 11 Notes Axial skeleton consists of: - Skull - Vertebral column: The cervical vertebrae support the weight of the head and neck, while the lumbar vertebrae support the weight of the trunk, head and neck. Protects the spinal cord The cervical spine offers the greatest movement capabilities (flexion, extension, rotation, lateral flexion). The thoracic spine is more stable, but permits rotation with limited flexion and extensions. The lumbar spine allows some flexion and extens...
