What does the term 'cannon bone' refer to in equine anatomy?

The term 'cannon bone' specifically refers to the long bone located in the lower leg of the horse, situated between the knee (or hock) and the fetlock joint. This bone plays a crucial role in supporting the horse’s weight and facilitating movement. It is an integral part of the leg structure, as it connects the upper part of the leg to the lower limb, allowing for flexibility and strength during activities such as running and jumping.

Understanding the anatomy of the cannon bone helps in diagnosing leg injuries and assessing the overall health of equine athletes. This knowledge is essential for anyone involved in horse care or riding, as it aids in recognizing signs of strain or injury in the equine limb.
