rectal epithelial cell
These cells include: B, F, Y, U, K' and K. All rectal epithelial cells contain secretory membrane stacks along this region facing the lumenal cuticle and produce some portion of the cuticular lining of the rectum. These are interfacial cells that connect the alimentary system to the main body syncytium.
tail precursor cell
Tail lateral ectoblasts that give rise to neurons, hypodermis and glial lineages. While initially identical, after the L2 lethargus the T cell lineages become markedly different between males and hermaphrodites helping to provide the sexually dimorphic tail structures found in males.
