- epithelial cell development variant
Any variation in the progression of an epithelial cell over time, from initial commitment of the cell to a specific fate, to the fully functional differentiated cell compared to control.
- epithelial system physiology variant
Animals exhibit variations in any physical or chemical process required for cells as a collective unit of the epithelial system to carry out their normal functions or activities or be able to perceive and respond to stimuli, compared to control animals.
- epithelial system morphology variant
Variations in the form, composition or structure of the epithelial system that serves to protect the organism from the external environment compared to control.
- epithelial cell physiology variant
Animals exhibit variations in any physical or chemical process required for the epithelial cell to carry out its normal functions or activities, compared to control animals.
- epithelial morphology variant
Variations in the form, composition or structure of the layer of cells that cover the external surface of an organism and form the inner lining between the tissues and organs of that organism and the external environment compared to control. In C. elegans epithelial cells include epithelium of the alimentary tract, intestinal cells, hypodermis, interfacial cells and somatic gonad cells (Wormatlas).
- epithelial attachment variant
Variations in the adhesion of the layer of cells that cover the external surface of an organism which serves to protect the animal from external environment compared to control.
- connected mitochondria
Mitochondria are interconnected by thin tubules of mitochondrial inner or outer membrane.
- epithelial development variant
Any variation in the progression of the epithelia over time, from its formation to its mature state compared to control. This process involves autonomously generated changes in epidermal cell shape and position, and interactions with internal tissues, including the developing nervous system and body wall muscles to affect epidermal enclosure, cell intercalation, and epidermal elongation.
