  1. Anatomy-Skeletal System Axial Skeleton

  2. Anatomy-Skeletal System Introduction • Refer back to your skeletal diagram where you named the bones of the body that you know. • As we progress through today’s lesson and label the bones, if the bone is one that you labeled correctly on your diagram, place a check mark next to the bone.

  3. Anatomy-Skeletal System Objectives • Students will be able to: • Define anatomical terms. • Identify the bones of the axial skeleton. • Label the bones.

  4. Anatomy-Skeletal System Terminology • Axial Skeleton • Consist of bones that form the axis of the skeleton; the skull, spinal column, breast bone and ribs. • Support and protect the organs of the head, neck and thorax. • Lungs, liver, kidneys

  5. Anatomy-Skeletal System Terminology • Articulate • Articulation • To unite by forming a joint/joints • Facet • A small, smooth, flat surface on a bone

  6. Anatomy-Skeletal System Terminology • Foramen • A natural opening, especially through a bone • Process • A projection away from the main part of the bone

  7. Anatomy-Skeletal System Axial Skeleton • Skull & Vertebral Column • Neck & spine • Neatly stacked bones • Affected by posture

  8. Anatomy-Skeletal System Axial Skeleton • Vertebral Column • Three divisions • By type • Size • Function • Constantly shifting

  9. Anatomy-Skeletal System Axial Skeleton • Vertebral Column • Cervical (7) • C1-Atlas • C2-Axis • Allow for rotation

  10. Anatomy-Skeletal System Axial Skeleton • Vertebral Column • Cervical (7) • Cartilaginous joints • Vertebral discs • Foramen for the spinal cord

  11. Anatomy-Skeletal System Axial Skeleton • Vertebral Column • Cervical • Highly mobile to allow for flexion, extension, rotation, circumduction & lateral bending

  12. Anatomy-Skeletal System Axial Skeleton • Vertebral Column • Thoracic (12) • Articulate with the ribs • Also highly moveable • Rotation, flexion, extension • Abnormal curvatures

  13. Anatomy-Skeletal System Axial Skeleton • Vertebral Column • Thoracic • Abnormal Curvatures • Scoliosis • Lateral curvature • Kyphosis • Posterior curvature

  14. Anatomy-Skeletal System Axial Skeleton • Vertebral Column • Thoracic • Foramen for the spinal cord • Distinguished by long transverse processes

  15. Anatomy-Skeletal System Axial Skeleton • Vertebral Column • Lumbar (5) • Largest bones • Trunk flexion & extension • Anterior curve • Lordosis

  16. Anatomy-Skeletal System Axial Skeleton

  17. Anatomy-Skeletal System Axial Skeleton • Vertebral Column • Sacrum (5) • Fused • Coccyx (4) • Fused • Tail bone

  18. Anatomy-Skeletal System Axial Skeleton • Vertebra Anatomy • Spinous process • Transverse process • Vertebral foramen • Vertebral body • Facet

  19. Anatomy-Skeletal System Axial Skeleton • Intervertebral Disk • Prone to injury due to compression

  20. Anatomy-Skeletal System Axial Skeleton Body Spinous Process

  21. Anatomy-Skeletal System Axial Skeleton • Cervical

  22. Anatomy-Skeletal System Axial Skeleton • Thoracic

  23. Anatomy-Skeletal System Axial Skeleton • Lumbar

  24. Anatomy-Skeletal System Axial Skeleton

  25. Anatomy-Skeletal System Axial Skeleton • Ribs • 12 pair • 7 true (1-7) • 5 false (8-12) • 2 floating (11-12)

  26. Anatomy-Skeletal System Axial Skeleton • Sternum • Manubrium • Body of the sternum • Xiphoid Process • Costal Cartilage
