The horse has a limited range of hip movement compared to the dog. This is mainly restricted to flexion and extension and is a result of the conformation of its [[Bones and Cartilages - Horse Anatomy|femoral head]], intra-articular ligaments and a large muscle mass around the joint. The '''ligament of the femoral head''' extends from the acetabulum to the fovea on the [[Bones and Cartilages - Horse Anatomy|femoral head]]. Unlike other species, the horse also has an extra ligament present in the joint; the '''accessory ligament'''. The accessory ligament arises from the tendon of insertion of the ''rectus abdominis'' muscle and to a lesser extent ''external abdominal oblique'' muscle as part of the ''prepubic tendon'' and inserts on the fovea. Both ligaments pass through '''acetabular notch'''.
