==Thoracic Limb==

When a horse is standing, muscles on opposite sides of the joints delicately contract and relax so that it stays in balance. This obviously puts considerable strain and stress on the muscles. To combat this, the horse has increased the fibrous content of many muscles. These collagenous muscles have been named collectively as the '''stay apparatus'''.  This is further divided into the '''suspensory apparatus''' and the '''check apparatus'''.

The check apparatus of the accessory ligament of the [[Tendons - Horse Anatomy#Flexors|deep digital flexor tendon]] is very similar to that of the forelimb. The superficial digital flexor muscle is entirely tendinous and so there is little/no muscle to be fatigued, thus a 'check' ligament would be of no advantage and so there is none in the hindlimb.
