- The equine spine - Horses like humans have 7 cervical (neck vertebrae), 18 thoracic vertebrae (humans have 12), 6 lumbar vertebrae (humans have 5), 5 sacral vertebrae and between 15-21 caudal or tail vertebrae.Horses unlike humans do not have a collar bone or clavicle. Instead their shoulder girdle is attached to the thorax (or ribcage) by a series of muscles comprising the thoracic sling.
- The equivalent of the human wrist in the horse or carpus is often incorrectly referred to as the knee. The actual knee of the horse is called the stifle. Imagine a human on all fours or a horse stood up like a human on two legs!
