*Horses have a region called the margo plicatus which separates the glandular and non-glandular parts of the equine stomach. The non-glandular area is lined with squamous epithelium (not columnar).

*A region called the margo plicatus is present which separates the glandular and non-glandular parts of the equine stomach. The non-glandular area is lined with squamous epithelium (not columnar).

*The equine stomach is relatively small (10% GIT) with a strong cardiac sphincter which prevents the animal from [[Control of Feeding - Anatomy & Physiology#The Vomit Reflex|vomiting]]. The equine stomach is rarely empty and retention time is short as expulsion into the [[Duodenum - Anatomy & Physiology|duodenum]] stops when feeding stops.

*Carnivores have a subglandular layer of fibroblasts and collagen fibres for protection, e.g. from consuming bones. It is between the glands and the lamina muscularis.
