The term 'Part of a Horse' can be broken down into three distinct parts: HOOF, POMMEL, and MANE. The HOOF is the hard outer covering of the horse's foot, which helps protect the sensitive inner structures of the foot. The POMMEL is the raised area at the front of the saddle, which provides support for the rider. Finally, the MANE is the long hair that grows along the horse's neck and back. All three of these parts are essential to the anatomy of a horse.
