Morphology and Anatomy:

Stichosome:

The pharynx is narrow and thin-walled anteriorly; posteriorly, is surrounded by unicellular, glandular stichocytes, each with a duct into the pharyngeal lumen. The pharynx  is almost devoid of musculature. The region of the pharynx surrounded by stichocytes is known as the stichosome.
