Bones ___________and give ________________to the
body. This framework helps protect
__________________ and furnishes attachment
points for ___________, _________________ and
___________. Bones also store minerals and
contain ______________________bone marrow.
3
Bone is a specialized form of ___________________t
issue containing about _____ solid matter and
______ water.
4
Bone consists of a hard outer shell called
___________ bone and an inner spongy structure
called ________________ or ____________________
bone
5
The bone surfaces are covered by a tough fibrous
vascular membrane called the _____________________

the developing bones is called.

The skeleton is divided into two main
parts________________ includes the skull,
vertebral column, ribs and sternum.______________
__ including the limbs

The skull includes two major segments___________
___ (brain case) and the __________________.All
skull bones are ____________except the

Vertebrae
Vertebral AnatomyThe horse has 37 vertebrae
Cervical (neck)- 7 Thoracic (chest) - 18
Lumbar (lower back) - 6 (except in Arabs - 5)
Sacral (pelvis) - 5 (fused) The dog has 31
vertebrae Cervical (neck)- 7 Thoracic
(chest) - 13 Lumbar (lower back) - 7 Sacral
(pelvis) - 3 (fused) The cat has 31 vertebrae
Cervical (neck)- 7 Thoracic (chest) - 13
Lumbar (lower back) - 7 Sacral (pelvis) - 3
(fused)

Cervicle vertebrae
16
C-1 and C-2 are called the _________ and the
___________. The words atlas (holding up the
world) and axis (what the world spins on) come
from Greek mythology. There can be an instability
in this area in large dogs that will cause
neurologic problems. The cervical vertebrae are
quite flexible, for obvious reasons.
17
As the cervical vertebrae become the
_____________ vertebrae they go past the shoulder
(S). The nerves that come off this
cervical-thoracic junction at the shoulder are
called the __________________(you cannot see
nerves on a plain radiograph). They innervate the
front legs on each side. Each of the thoracic
vertebrae corresponds to a __________ (R) on each
side of the chest
18
As we continue down the thoracic vertebrae you
can visualize how high their dorsal ____________
________________are. Also notice how these
processes start to get smaller as we get closer
to the ______________vertebrae 
19
Moving towards the end of the thoracic vertebrae
we come to what is termed the ____________________
__(T-L) junction. It is a very common area to
have VSC disease. As we pass into the
_________________ vertebrae we have now made our
way into the lower back.
20
The 7 _______________ vertebrae eventually lead
into the _________________ vertebrae (S). The
____________ sacral vertebrae are hard to
visualize because they are within the
___________________. After the sacrum we are at
the ________.

ribs

_______________ (collarbone)In the feline a
small flat bone attached to the ____________In
the canine a _________ bone that is not attached
to any other bone and may be __________ in some
dogs.
