- pharyngeal muscle physiology variant
Animals exhibit variations in any physical or chemical process required for muscles in the pharynx to carry out their normal functions or activities or be able to perceive and respond to stimuli, compared to control animals.
- extra pharyngeal muscle cells
Animals contain an excess number of pharyngeal muscle cells compared to control. In C. elegans, pharyngeal cells are derived from MS-blastomere. The overproduction of pharyngeal tissues is a result of other blastomeres adopting an MS-like fate.
