- touch receptor cell morphology variant
Animals exhibit variations in the structure or composition of any neuron within the class of sensory neurons responsible for relaying mechanical stimuli to the animal compared to control.
- shrinker
The whole body undergoes longitudinal shortening in response to head touch or tail touch (Wormatlas).
- light touch habituation variant
Any variation in the decreased behavioral response to repeated light head or tail touch compared to control. A gentle touch to the animal's head causes backward movement, whereas a gentle touch to the animal's tail causes forward movement. When wild-type animals are touched repeatedly on the head or tail, after some repetition they stop responding to the touch stimulus.
- differential touch sensitivity variant
Animals differ from control animals in response to mechanical stimulation targeting different parts of the same cell. In N2 wild-type animals, response to touch near the ALM cell body is reduced compared with touch of the cell area near the second pharyngeal bulb.
- touch resistant
Variations in characteristic response with respect to perception or transmission of a touch stimulus compared to responses in control animals.
- nose touch hypersensitive
Animals tend to initiate a response more often, compared to control, after nose-on collisions with an object. In C. elegans, animals initiate backwards movement in response to nose touch.
- receptor mediated endocytosis defective
Animals exhibit defects in the cell-mediated uptake of external materials via receptor activity. Receptor-mediated endocytosis ensures specificity of transport and generally occurs via clathrin-coated pits and vesicles. In C. elegans, this is often judged by the lack of yolk uptake in oocytes.
