WormMine: ExpressionPattern Expr12103

• Pattern: Eggs already showed the corresponding GFP fluorescence, with more and more tissues following during development (L1 larval stage: pharynx, excretory cell, some sensory neurons; L2-L4 larval stages: intestine, rectal sensory neurons; adult worms: longitudinal muscles, gonads). The rare males showed GFP expression in their spermathecae. Within the anterior part of the nervous system, GFP expression was detected in the pharyngeal nerve ring and in some sensory neurons. Within its posterior part, lumbar ganglia and the dorso-rectal ganglion showed GFP expression.

an accordion-like tube that contains sperm and is the site of oocyte fertilization.	spermatheca		WBbt:0005319
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
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 most extensive region of neuropil in the animal, consists of a large toroidal bundle of processes.	nerve ring	circumpharyngeal nerve ring	WBbt:0006749
organ producing either sperm or ova.	gonad		WBbt:0005175
neuron that senses external stimuli and transduce them to signals internal to the organism.	sensory neuron		WBbt:0005759
The left and right lumbar ganglia lie behind the pre-anal ganglion in the tail, in lateral positions. Each contains 12 neuron cell bodies that send most of their neuronal processes into the ventral nerve cord via lumbar commissures and the pre-anal ganglion. There is no local neuropil in these ganglia in the hermaphrodite, instead they form most synapses in the pre-anal ganglion. Most lumbar neurons have sensory functions. In the adult male tail, these two ganglia gain many additional neurons and have some local neuropil. The lumbar neurons lie in close association with the lateral hypodermis, and most are posterior to the anus.	lumbar ganglion	lumbar lateral ganglia	WBbt:0005830
Gonochoristic organism that can produce male gametes.	male	male organism	WBbt:0007850
neuron whose cell body is in the dorsal-rectal ganglion.	dorsal-rectal ganglion neuron	dorso-rectal ganglion neuron	WBbt:0005801
cell that exists in and is part of an embryo.	embryonic cell		WBbt:0007028
