Which term refers to furrows between the frog and the sole of the hoof?

The term that refers to the furrows between the frog and the sole of the hoof is "sulci." In equine hoof anatomy, sulci are the grooves or indentations found on the underside of the hoof, specifically around the frog area. These structures play an important role in the health and function of the hoof, helping to facilitate proper drainage, provide traction, and allow for some flexibility during movement.

Understanding the anatomy of a horse's hoof, including the sulci, is essential for both hoof care and assessing overall equine health. The presence and condition of the sulci can give insights into how well the hoof is functioning, and any abnormalities in this area can signal potential issues that may need to be addressed.
