- tail swelling
Swelling in the post anal region compared to control. In C. elegans this swelling can be associated with infection from the nematode-specific bacterial pathogen, Microbacterium nematophilum.
- dorsorectal ganglia development variant
Any variation in the progression of the ganglion which lies above and behind the rectum in the tail, in close continuity with the anal hypodermal ridge over time from its initial formation to its mature form compared to control (Wormatlas).
- expulsion defective
Animals exhibit defects in the expulsion of gut contents. In C. elegans, this refers to the final step of the defecation cycle in which the intestinal muscle and anal depressor contractions further pressurize intestinal contents and open the anus to permit expulsion.
- lumbar ganglia development variant
Any variation in the progression of the left and right lumbar ganglia which lie behind the pre-anal ganglion in the tail, in lateral positions over time from its initial formation to its mature form compared to control (Wormatlas).
- expulsion variant
Any variation in the expulsion of gut contents compared to control. In C. elegans, this refers to the final step of the defecation cycle in which the intestinal muscle and anal depressor contractions further pressurize intestinal contents and open the anus to permit expulsion.
