A chain of very large cuboidal cells forming a wide central lumen in which food arrives from the posterior pharynx, is digested, and from which waste products proceed to the rectum. Intestinal rings form in groups of two and four cells surrounding the common lumen; thus the epithelium is only one cell deep at any point, with neighboring cells firmly secured to their neighbors by apical adherens junctions. These cells have very large nuclei and many large vacuoles, yolk granules, and other inclusions; the latter increase in number and electron density as the animal ages. |

five pairs of thin gonadal sheath cells form a single layer covering the germ line component of each arm, each pair occupying a stereotyped position along the gonad proximal-distal axis. |

The components of the gonad that are separate from the germline proper. In hermaphrodite, these include five tissues which are all derived from the somatic primordium : the distal tip cells, the gonadal sheath, the spermatheca, the spermatheca-uterine valve (sp-ut) and the uterus. |
