*Keratinised stratified squamous epithelium
*Non-glandular
*No lamina muscularis
*2 thick layers of tunica muscularis- inner circular and outer longitudinal
*Interior surface of the rumen forms numerous papillae
**Papillae can be long and foliate
**Papillae can be short and pointed
**Up to 6mm in length
**Animals fed on rough grass or in the dry season have longer papillae
**Animals fed on digestible feed or in the wet season have shorter papillae (1-2mm in length)
**Fewer dorsally
**Increase surface area for [[Volatile Fatty Acids|volatile fatty acid]] absorption
*The upper keratinised layer of papillae protects against abrasion
*The deeper layers of papillae metabolise the [[Volatile Fatty Acids|volatile fatty acids]]
