- dauer excretory gland variant
Dauer stage animals exhibit variations in the form, structure or composition of a pair of large cells in the head that fuse to form a single gland whose contents are released into the excretory duct through a specialized secretory membrane, compared to control (Wormatlas).
- excretory gland cell development variant
Any variation in the progression of a gland cell of the secretory-excretory system over time, from initial commitment of the cell to a specific fate, to the fully functional differentiated cell compared to control.
- excretory gland cell morphology variant
Animals exhibit variations in the form, structure or composition of a pair of large cells in the head that fuse to form a single gland whose contents are released into the excretory duct through a specialized secretory membrane, compared to control (Wormatlas).
- excretory duct cell development variant
Variations in the progression of an interfacial epithelial cell which forms a lumen to receive the outflow of the excretory gland and excretory canal cells, over time from an initial condition to a later condition compared to control animals.
- excretory system development variant
Variations in the progression of the excretory system over time, from its formation to the mature structure. The excretory system is required for the elimination of metabolic waste. In C. elegans, the excretory system is comprised of the excretory cell, excretory duct cell and excretory socket cell.
- excretory secretory system development variant
Any variation in the progression of the excretory secretory system over time, from its formation to its mature state compared to control. The excretory secretory system consists of the excretory system and its associated glands.
- excretory secretory system morphology variant
Variations in the form, structure or composition of related tissues that allow the animal to secrete saline fluid and maintain a proper salt balance compared to control. In C. elegans, four cell types (1 pore cell, 1 duct cell, 1 canal cell and a fused pair of gland cells) make up the excretory system (Wormatlas).
