pastern

This term is a specialized anatomical descriptor used primarily in equine science, veterinary medicine, and horse breeding. It refers specifically to the region of the lower limb that absorbs shock during movement, making it a critical point of interest for judges in conformation shows and veterinarians diagnosing lameness.

Because it is a technical term of art, it is rarely encountered in general conversation and is almost exclusively used within the context of horse husbandry. It describes a specific physical structure rather than a general body part, distinguishing it from the fetlock above and the hoof below.
