*Keratinised stratified squamous epithelium
+
The reticulum has a '''keratinised stratified squamous epithelium''' and no present glands. The reticulum has a honeycomb appearance of short and tall folds, as the mucosal layer is thrown into folds. The folds gradually merge into '''papillae''', where the reticulum meets the rumen. [[Tongue - Anatomy & Physiology#Types of Papillae|Conical papillae]], also called secondary papillae, are present on folds, providing a rough surface to increase food breakdown.

The '''lamina muscularis''' is present as discrete bands of smooth muscle (not continuous). There are 2 thick layers of '''tunica muscularis''', the inner circular and the outer longitudinal. The upper keratinised layer of the reticulum protects against abrasion and the deeper layers metabolise [[Volatile Fatty Acids|volatile fatty acids]].
