Skull Skeleton Quiz
3 parts
1. matching
Make sure you know that some of these have more than one answer
Bones (letters on left) may be used more than once
2. lab practical
Go back one at a time (this may go slowly)
3. virtual lab practical
We will go through these together
Ask questions if needed

Vertebrae Fig 7-12
As you age your vertebral column curves to adjust for walking upright as well as weight gains
Cervical curve - concave
Thoracic curve - convex
Lumbar curve - concave
Sacral curve - convex

7. Vertebrae Cervical Vertebrae 1st = atlas 2nd = axis
7/12/2019
Vertebrae
Cervical Vertebrae
1st = atlas
allows movement up and down
Articulates with occipital condyles
2nd = axis
allow movement from side to side
odontoid process - articulates with atlas
Smaller and lighter than other vertebrae

8. Vertebrae Thoracic Lumbar attach to ribs very thick
7/12/2019
Vertebrae
Thoracic
attach to ribs
Lumbar
very thick
used to support much body weight
many injuries occur here

9. Vertebrae Sacrum Coccyx 5 fused vertebrae Posterior region of pelvis
7/12/2019
Vertebrae
Sacrum
5 fused vertebrae
Posterior region of pelvis
Coccyx
3 to 5 fused bones
found at the end of the sacrum
Will bend when sitting

10. Ribs True ribs False ribs
7/12/2019
Ribs
True ribs
attach to sternum via costal cartilage (hyaline cartilage)
False ribs
indirect or no connection with the sternum
Floating ribs
ribs with no connection with the sternum

11. Sternum manubrium - superior region body - middle portion - largest
7/12/2019
Sternum
manubrium - superior region
body - middle portion - largest
Xiphoid process - inferior most region
important in CPR

7/12/2019
How and why is the vertebral column curved?
What are structural differences between cervical and lumbar vertebrae
What types of cartilage are found in the ribs & sternum and vertebrae? Why are they different?
What purpose do the vertebrae and ribs serve?
