Skeleton of the dog

You can find more about dogs here

The canine skeletal system is a marvel of bones, cartilage,
and ligaments that provide the body with a framework to
erect on four strong legs, protect internal organs, and
provide a full range of motion. The muscles furnish the
power to propel the dog into action, but without healthy
bones, joints, and connective tissue, the muscles cannot do
their job.

The dog’s body has several types of joints: ball and socket
such as the hip and shoulder joints; hinged joints such as
the knees and elbows; and gliding or plane joints such as
the wrists and ankles. The joints are lubricated for smooth
action by synovial fluid and are stabilized by tendons and
ligaments.



Skeleton
of the dog


1 = Upper jaw

2 = Lower jaw

3 = Orbit

4 = Cervical vertebrae (bones of the neck)

5 = Thoracic vertebrae (the bones that form the dorsal
part of the thoracic cage)

6 = Lumbar vertebrae (the bones of the lumbar region of
the back)

7 = Sacrum (the set of sacral vertebrae)

8 = Caudal vertebrae (the bones of the tail)

9 = Pelvis

10 = Femur

11 = Patella (bone that allows the flexion of the thigh
on the gaskin), knee cap

12 = Tibia

13 = Fibula

14 = Metacarpus

15 = Phalanges

16 = Scapula (shoulder blade)
17 = Ribs

18 = Sternum (bone forming the underside of the
thoracic cage)

19 = Humerus

20 = Ulna

21 = Radius (forearm bone)

22 = Metatarsus

23 = Pahalnges

Some joints:

a = Shoulder joint

b = Elbow

c = Carpus (wrist bone)

d = Hip

e = Knee

f = Tarsus (bone forming the joint between the tibia
and the metatarsus), hock joint

A joint is the location at which two
bones make contact (articulate). Joints are
constructed to both allow movement and provide
mechanical support. The alteration of dog joints can
be caused by general infectious or degenerative
diseases, traumas or localized infections in the joint
itself. When a joint doesn’t work adequately it’s
because something is wrong on the bones, muscles,
ligaments, tendons or nerves that are around the
joint. The symptoms are pain, rigidity, swelling
up, reddening, the rising of the local temperature and
a loss of control of body movements > Osteoarthritis.
