Axial Skeleton

2. Anatomy-Skeletal System Bell 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 Mandible
Orbit 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

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 Skeleton Vertebra 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

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. DO NOT TOUCH THE BONES AT YOUR TABLES!
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!
