| 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. | intestine | gut | WBbt:0005772 |
| female genital. | vulva | WBbt:0006748 | |
| an accordion-like tube that contains sperm and is the site of oocyte fertilization. | spermatheca | WBbt:0005319 | |
| Epidermal layer. | hypodermis | epidermis | WBbt:0005733 |
| Longitudinal bands of muscle cells surrounding animal body, with one band running in each quadrant of the body, regulated contraction and relaxation of these muscles cause locomotion. | body wall musculature | body muscle | WBbt:0005813 |
| the feeding organ, a neuro-muscular pump in the head of the animal, used to ingest food, bacteria suspended in liquid, filter them out, grind them up and transport posteriorly into the instestine. | pharynx | esophagus | WBbt:0003681 |
| H-shaped cell associated with the excretory system, largest cell in C. elegans. | excretory cell | excretory canal cell | WBbt:0005812 |
| 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. | somatic gonad | somatic germline | WBbt:0005785 |
| 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. | tail precursor cell | T cell | WBbt:0008409 |

|---|---|---|---|---|
| The stage that begins when a C.elegans individual is fully-developed and has reached maturity. | adult Ce | WBls:0000041 | ||
| A developmental life stage of the nematode Caenorhabditis elegans that occurs from egg hatching until adulthood. | larva Ce | WBls:0000023 | ||
| The C. elegans life stage spanning 290-350min after first cleavage at 20 Centigrade. Proliferate from 421 cells to 560 cells. The stage when embryo just finished gastrulation and is enclosing. | enclosing embryo Ce | WBls:0000013 | ||
| The C. elegans life stage spanning 100-290min after first cleavage at 20 Centigrade. Proliferate from 28 cells to 421 cells. Referring to the whole period of gastrulation. | gastrulating embryo Ce | WBls:0000010 | ||
| The C. elegans life stage spanning 520-620min after first cleavage at 20 Centigrade. Cell number remains at ~560 cells, with some new cells generated and some cells go through programmed cell death. The shape of embryo is elongated and tripple fold. A stage between 2-fold embryo and fully-elongated embryo. Also called pretzel embryo or pretzel stage. | 3-fold embryo Ce | WBls:0000020 | ||
| The C. elegans life stage spanning 420-460min after first cleavage at 20 Centigrade. Cell number remains at ~560 cells, with some new cells generated and some cells go through programmed cell death. The shape of embryo is elongated and fold back 50%. A stage between comma embryo and 2-fold embryo. | 1.5-fold embryo Ce | WBls:0000018 | ||
| The C. elegans life stage spanning 390-420min after first cleavage at 20 Centigrade. Cell number remains at ~560 cells, with some new cells generated and some cells go through programmed cell death. The shape of embryo looks like a comma. A stage between bean embryo and 1.5-fold embryo. | comma embryo Ce | WBls:0000017 | ||
| The C. elegans life stage spanning 460-520min after first cleavage at 20 Centigrade. Cell number remains at ~560 cells, with some new cells generated and some cells go through programmed cell death. The shape of embryo is elongated and double fold. A stage between 1.5-fold embryo and 3-fold embryo. | 2-fold embryo Ce | WBls:0000019 | ||
| The C. elegans life stage spanning 350-390min after first cleavage at 20 Centigrade. Cell number remains at ~560 cells, with some new cells generated and some cells go through programmed cell death. Emrbyo elongation started but have not formed comma shape yet. The shape of embryo looks like a lima bean. A stage right before comma embryo. Also called lima embryo or lima bean stage. | bean embryo Ce | WBls:0000016 |
