A group of six equivalent cells forms a tightly constructed `valve` that links the posterior bulb of the pharynx to the anterior four cells of the intestine. These six cells comprise a small epithelial channel with a cuticular lining in continuity with the pharyngeal cuticle and link the lumen of the pharynx to the large lumen of the anterior intestine. |

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. |

|
|
A set of three longitudinal nerves (I1L, NSML and M2L) running along the anterior/posterior axis within the pharynx, each lying within a narrow groove created between syncytial pairs of muscles. One nerve lies dorsally, in close apposition to the dorsal gland duct, while the other two nerves lie subventrally. |
