Which vertebral level corresponds to the withers in equine anatomy?

• A. C7–T2
• B. T3–T8
• C. L1–L3
• D. T1–T4

Answer: (B)

The withers sit at the highest point of the horse’s back at the base of the neck, over the mid-thoracic part of the spine. The vertebrae underlying that region are the mid-thoracic vertebrae, typically around the third through the eighth thoracic vertebrae. This aligns with where the scapula and back muscles sit, behind the shoulder girdle, and clearly separates it from the cervical (neck) vertebrae and the lumbar (loin) vertebrae. So the correct range is roughly T3 to T8. Ranges that are too cranial would be near the neck, and ones that are too caudal would be near the loin, which isn’t where the withers are.
