The structure of the cells lining the stomach of the tammar wallaby (Macropus eugenii).

The stomach of the tammar may be divided into cardiac, "oesophageal", fundic and pyloric regions. In the cells of the cardiac region (which occupy 65% of the stomach) at least three types of mucous droplet are present. The stratified squamous "oesophageal" region occupies 20% of the stomach and the fundic and pyloric regions make up the remaining 15%. The cellular structure of the three last named regions seems to be similar to that described for other monogastric mammals. Endocrine cells were found in all glandular regions.
