- dauer buccal cavity morphology variant
Variations in the form or composition of the cuticle-lined lumenal region which lies just behind the lips at the entrance to the pharyngeal lumen in dauer stage animals compared to control (Wormatlas).
- preanal ganglion development variant
Any variation in the progression of the ganglion which lies at the posterior limit of the ventral nerve cord in the tail over time from its initial formation to its mature form compared to control (Wormatlas).
- touch resistant anterior body
Animal does not respond to stroking in the anterior body region with a hair or similar fiber compared to control. In C. elegans, the anterior region is defined as the body region that lies between the posterior bulb of the pharynx and the vulva.
- ventral ganglion development variant
Any variation in the progression of the ganglion which lies ventrally beside the nerve ring in the head, just anterior of the retrovesicular ganglion over time from its initial formation to its mature form compared to control (Wormatlas).
- 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).
- M line absent
Animals lack the planar structure within the muscle sarcomere which lies midway within the thick filament (A) band, attaching to the plasma membrane at its base and running up towards the inward surface of the myofilament lattice, compared to control animals (Wormatlas).
- touch resistant tail
Failure to execute a characteristic response when struck or stroked in the posterior region. In C. elegans, animals move forward movement when struck or stroked in the posterior region, usually with a hair or similar fiber. The posterior region lies between the vulva and the tail.
- retrovesicular ganglion development variant
Any variation in the progression of the ganglion which lies at the anterior limit of the ventral nerve cord, near the ventral ganglion and nerve ring in the head posterior to the excretory pore over time from its initial formation to its mature form compared to control (Wormatlas).
- hook development variant
Any variation in the development of the structure that lies on the ventral surface just anterior and central to the base of the spicule openings (small lump on the gubernaculum of the male tail) and contains a sensory structure called the hook sensillum, compared to control. In C. elegans the hook is necessary for proper male mating.
