 40 forelimb

 40 hindlimb (including pelvis)
                  Front Legs

   The horse has no collarbone
   Front legs are not attached by joints
   A sling of muscles and ligaments supports the
    weight of the horse and rider.
                    Sleeping
   Horse's can sleep in the upright position
    without falling over
   Due to a 'locking' mechanism in the fore and
    hindlimbs
   The main joints can be locked into position by
    a system of muscles and ligaments mostly
    based around the suspensory ligament at the
    back of the cannon bone.
   Very little energy is needed to hold the 'lock'
