Micrograph of Oesophagus:

This micrograph shows the wall of the oesophagus
The lumen is lined by a stratified squamous non-keratinising epithelium (similar to the type found in the oral cavity)
Deep to the epithelium lies the (connective tissue) lamina propria and then the muscularis mucosae (MM)
On the left of the micrograph a large mucus secreting gland is present
A duct (arrow) can be seen passing from this gland through the mucous membrane
In life this duct would carry the mucus into the lumen of the oesophagus
