The Vertebral Column
Figure 7.5 is a lateral view of the vertebral column. Identify each numbered
region of the column by listing in the answer blanks the region name first
and then the specific vertebrae involved (for example, sacral region, Sÿ to
Sÿ ). Also identify the modified vertebrae indicated by numbers 6 and 7 in
Figure 7.5. Select different colors for each vertebral region, and use them to
color the coding circles and the corresponding regions.

The following statements describe the characteristics of the vertebrae
composing the vertebral column. Using the key choices, identify, each
structure or region by inserting the appropriate letters in the answer blanks.
KEY CHOICES
A. Atlas
C. Cervical vertebramtypical
B. Axis
D. Coccyx
E. Lumbar vertebra
F. Sacrum
G. Thoracic vertebra
Type of vertebra containing foramina in the transverse processes, through which the
vertebral arteries ascend to reach the brain
Its dens provide a pivot for rotation of the first cervical vertebra
.. '.' ;.
Transverse processes have facets for articulation with ribs: spinous process points
sharply downward
4.
Composite bone; articulates with the hipbone laterally
Massive vertebrae; weight-sustaining
"Tail-bone"; vestigial fused vertebrae
7.
Supports the head; allows the rocking motion of the occipital condyles
8,
Seven components; unfused
9, Twelve components; unfused
10. No intervertebral disk between these two bones
