What is the term for a row of teeth in a horse?

The term "arcade" refers to a row of teeth in a horse. In equine dental terminology, the arcade is used to describe the arrangement of the teeth in the upper and lower jaws. Horses typically have two arcades, one for the upper teeth and one for the lower teeth, and each arcade contains incisors, canines, premolars, and molars. The proper identification of the arcade is essential for understanding equine dental health, as it plays a crucial role in the horse's ability to chew and process food effectively.

The other terms do not accurately describe a row of teeth in this context. "Tract" generally relates to a pathway or course, usually not associated with dental terminology. "Ridge" refers to a raised line or edge but does not specifically denote a line of teeth. "Lineage" relates to ancestry or descent, which is unrelated to the structure of teeth in a horse's mouth. Understanding these distinctions reinforces the correct use of dental terminology in the context of equine care and evaluation.
