Many sulci are the product of a surface fold or junction, such as in the gums, where they fold around the neck of the tooth. The term sulcus is used in invertebrate zoology to describe folds, grooves, and boundaries, especially at the edges of sclerites or between segments. In botany and palynology, the surface morphology of seeds and pollen grains is termed sulcate if one or more sulci form major features.

If we feel gratitude, we may especially not want to see someone else suffer because they donât have enough. Gratitude helps us know the difference between needs and wants, between the essentials and the whims of the now. We might want a candy bar right now (and oh do we), but it isnât what we need.
