| 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 |
| type of cells that make up muscle layers in the pharynx. | pharyngeal muscle cell | WBbt:0005451 | |
| 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 |
| Epidermal layer. | hypodermis | epidermis | WBbt:0005733 |
| 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 |
| neuron with its cell body situated in the head, excluding the pharynx. | head neuron | WBbt:0006751 | |
| a group of hypodermal cells that lie along the apical midline of the hypodermis, at the extreme left and right sides between nose and tail | seam cell | lateral hypodermis | WBbt:0005753 |

7 Life Stages
| Remark | Definition | Other Name | Public Name | Primary Identifier |
|---|---|---|---|---|
| The stage that begins when a C.elegans individual is fully-developed and has reached maturity. | adult Ce | WBls:0000041 | ||
| The third stage larva. At 25 Centigrade, it ranges 32.5-40 hours after fertilization, 18.5-26 hours after hatch. | L3 larva Ce | WBls:0000035 | ||
| The second stage larva. At 25 Centigrade, it ranges 25.5-32.5 hours after fertilization, 11.5-18.5 hours after hatch. | L2 larva Ce | WBls:0000027 | ||
| The fourth stage larva. At 25 Centigrade, it ranges 40-49.5 hours after fertilization, 26-35.5 hours after hatch. | L4 larva Ce | WBls:0000038 | ||
| The first stage larva. At 25 Centigrade, it ranges 14-25.5 hours after fertilization, 0-11.5 hours after hatch. | L1 larva Ce | WBls:0000024 | ||
| The C. elegans life stage spanning 620-800min(hatch) 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. A stage after elongation is over. The last stage of embryogenesis. Also called pre-hatched embryo, late embryo or morphogenetic embryo. | fully-elongated embryo Ce | WBls:0000021 | ||
| The C. elegans life stage spanning 350-620min 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 stage that embryo starts elongation until elongation is over. | elongating embryo Ce | WBls:0000015 |
