The oesophagus has a '''stratified squamous epithelium'''. It has mucosal folds present for distension. The degree of keratinisation of the oesophagus depends on the animal's diet.
The '''lamina propria''' of the oesophagus contains collagen and elastic fibres that are sparsely distributed. The '''lamina muscularis''' of the oesophagus is smooth or skeletal muscle, depending on the species. The inner circular layer of the '''tunica muscularis''' thickens near the gastric junction, forming a sphincter.
Whilst there are no glands present in the mucosa, there are mucous glands (tubulo-acinar) present in the submucosa.
