Anatomy-Skeletal System

1. Anatomy-Skeletal System Axial Skeleton

2. Anatomy-Skeletal SystemBell Work • 1 person from your table grab 1 mini skeleton • 1 person from your table grab supply boxes • Grab wkst from front table • On your bell work sheet, list as many bones as you can remember that we covered yesterday on the skull {11} (independent work!)

3. Using the tape at your tables, grab the sharpie and label the tape 1-11 • Mastoid process 7. Nasal • Parietal 8. Sphenoid • Temporal 9. Occipital • Frontal 10. Mandible • Orbit 11. Maxilla • Zygoma

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

5. 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.

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

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

8. Anatomy-Skeletal System Axial Skeleton • Skull & Vertebral Column

9. Anatomy-Skeletal System Axial Skeleton • Vertebral Column

10. Anatomy-Skeletal System Axial Skeleton • Vertebral Column • Cervical (7) • C1-Atlas • C2-Axis

11. Anatomy-Skeletal System Axial Skeleton • Vertebral Column • Cervical (7) • C1-Atlas • C2-Axis

12. Anatomy-Skeletal System Axial Skeleton • Vertebral Column • Cervical (7) • C 1-7

13. Anatomy-Skeletal System Axial Skeleton • Vertebral Column • Thoracic (12) • Articulate with the ribs

14. Anatomy-Skeletal System Axial Skeleton • Vertebral Column • Thoracic (12) • Articulate with the ribs

15. Anatomy-Skeletal System Axial Skeleton • Vertebral Column • Lumbar (5)

16. Anatomy-Skeletal System Axial Skeleton • Vertebral Column • Lumbar (5)

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

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

19. Anatomy-Skeletal System Axial Skeleton • Intervertebral Disk The intervertebral disks are situated between the vertebral bodies of each vertebra

20. Anatomy-Skeletal System Axial SkeletonVertebra Comparison • As the vertebral column moves from the cervical region to the lumbar region, the spinous process becomes shorter and angled more inferiorly. • Spinous process changes lead to a decrease in mobility • The vertebral body becomes larger • Vertebral body changes are necessary to bear more weight Body Spinous Process

21. Anatomy-Skeletal System Axial SkeletonVertebral Comparison • Cervical

22. Anatomy-Skeletal System Axial SkeletonVertebral Comparison • Thoracic

23. Anatomy-Skeletal System Axial SkeletonVertebral Comparison • Lumbar

24. Anatomy-Skeletal System Axial SkeletonVertebral Curves

25. Bell Work 1 2 11 3 4 5 6 12 • In your bell work log, label the different areas we covered yesterday in class! • Try not to use your notes!! 7 8 9 10

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

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

28. Closure • In your own words… • Define foramen • Define process • List the bones of the axial skeleton • What is lateral curvature of the spine called? • What part of the vertebra must get bigger as we progress down the spine?

29. Bell Work On your bell work sheet, define the terms foramen, articulation, and process What bones make up the axial skeleton? What is their main purpose? DO NOT TOUCH THE BONES AT YOUR TABLES!
