Cervical Vertebrae
All vertebrae have a
common structural
pattern (as seen in
previous slide).
Vertebrae of each
region also have
certain
characteristics.
C1 (_____), for
example, has no body
or spinous process
dens
C2 (____) has a typical body
& spine but also features a
knoblike tooth called a “dens”
Cervical Vertebrae continued
C3 – C7 have the following distinguishable
characteristics (fill in your notes as I discuss):
1. The_____ is oval – wider from side to side.
2. Except for C7, the ________ ________ is short
and split at the top.
3. Vertebral _____ is large and __________.
4. Each transverse process contains a
_________ __________ through which the
vertebral arteries pass to service the brain.
Thoracic Vertebrae
• All ________ with the ribs and have 5 other
characteristics:
1. Body is heart-shaped and bears two small
______ (small joints)
2. Vertebral _______ is circular.
3. Spinous _______ is long & points sharply
downward.
4. With the exception of T11 – T12, the transverse
_______ have facets.’
5. Sup. & inf. articular facets lie in the frontal
plane (preventing ________ & extension but
allows for rotation).
Lumbar Vertebrae
• Sturdy & larger with 4 other notable
characteristics:
1. The ______ and laminae are shorter &
thicker than other vertebrae.
2. The spinous ________ are short, flat,
and hatchet-shaped.
3. The ______ ________ is triangular.
4.The _____ orientation helps to lock
them together.
