What is "stichosome"

Stichosome (from Greek stichos = row; soma = body) is a multicellular organ that is very prominent in some stages of nematodes and consists of a longitudinal series of glandular unicellular cells ( stichocytes) arranged in a row along the oesophagus that form the posterior esophageal glands. It opens into the esophageal lumen and apparently functions as a secretory gland and storage organ.
