What is the main function of the suspensory apparatus of the distal phalanx in horses?

What is the main function of the suspensory apparatus of the distal phalanx in horses?

The suspensory apparatus of the distal phalanx is a network of collagen bundles which connects the distal phalanx to the stratum internum and permits the hoof wall to act as a principal weight-bearing structure.

Why do horses need reciprocal apparatus?

The second element, the reciprocal mechanism (illustrated in DARK RED), ensures that the stifle and hock joints work in unison with one-another. This mechanism allows the horse to navigate the pelvic limb in a smooth and coordinated manner.

What is the function of the ligamentous apparatus in a horse?

The passive stay apparatus of the frontlimb enables a horse to rest while standing and use a minimal amount of muscular energy to do so. Instead of using muscles to stabilise joints, this function is performed by tendons and ligaments which do not fatigue to the same extent.

What is the function of the suspensory apparatus?

The stay apparatus allows animals to relax their muscles and doze without collapsing. (Horses are able to sleep lying down as well.) The stay apparatus is an arrangement of muscles, tendons and ligaments that work together so that an animal can remain standing with virtually no muscular effort.

What is the function of suspensory ligaments?

This ligament is responsible for maintaining and supporting the position of the eyeball in its normal upward and forward position within the orbit, and prevents downward displacement of the eyeball. It can be considered a part of the bulbar sheath.

What is the stay apparatus in horse?

How do horses lock their legs?

In the normal horse, the patella’s function is to sometimes ‘lock’ in an upward position when the medial patella ligament hooks over a ridge on the end of the femur. This is the reason that horses can sleep standing up, or rest one leg for long periods.

What causes suspensory ligament injuries in horses?

How does the suspensory ligament become damaged? The ligament and its branches are strong but only slightly elastic. Excessive stress can occur to the ligament when a horse lands after a jump or when it travels at fast speeds. Essentially, an over-stretching injury can occur resulting in damage to the ligament.
