Horse anatomy consists of various systems that work together to support movement and overall health. The skeletal system includes over 200 bones, providing structure and protection for vital organs. Key components include the skull, spine, and limbs, which allow horses to run and jump effectively. Muscles play a crucial role in horse anatomy, enabling movement and strength. Major muscle groups include the forelimbs and hindquarters, which are essential for propulsion. Additionally, the respiratory and circulatory systems support endurance and stamina, making horses well-adapted for various activities, from racing to dressage.
