What part of the horse's foot lies immediately above the frog?

The digital cushion is a key structure located immediately above the frog in a horse's foot. It plays a vital role in the overall health and function of the hoof. The digital cushion is composed of a fibrous, elastic connective tissue and acts as a shock absorber when the horse is in motion, helping to protect the sensitive structures of the foot from impact forces. This structure also assists with blood circulation within the foot as the horse moves, aiding in the overall health of the hoof.

Understanding the placement and function of the digital cushion is essential for anyone involved in horse care, as it highlights the importance of proper hoof care and management. Recognizing that this structure is situated right above the frog underscores its role in the biomechanical dynamics of the hoof. The other structures listed, such as the navicular bone, coronary band, and bulb of heel, have different locations and functions within the hoof anatomy. The navicular bone, for instance, is located behind the coffin bone and is involved in the movement of the pedal bone. The coronary band is at the top of the hoof wall and is responsible for growth, while the bulbs of the heel are located at the rear of the hoof and provide additional cushioning and support. Thus, identifying the digital cushion as the
