What are the main skeleton muscle that relate to locomotion in the horse?

The main skeletal muscles involved in locomotion in horses include the gluteal muscles, which help in hip extension and propulsion, and the quadriceps, which facilitate knee extension. The hamstrings are crucial for flexing the hind limb and aiding in powerful strides. Additionally, the pectoral muscles assist in forelimb movement and stabilization during motion. Together, these muscle groups enable efficient and coordinated movement essential for a horse's locomotion.
