Anatomical terminology

The esophageal glands are small compound racemose exocrine glands of the mucous type.

There are two types:

  • Esophageal glands proper- located in the submucosa and secrete acid mucin for lubrication
  • Esophageal cardiac glands- in the lamina propria and secrete neutral mucus that protects the oesophagus from acidic gastric juices.

Each opens upon the surface by a long excretory duct.
