Ingrowth: In medicine, this is the transition of one phase of the inflammatory process to another after an acute one. In psychology, this is a term that denotes the process of integrating a person into a new environment, for example, a new team.
Both psychology and medicine use this term to describe the process of the body healing a new environment, but in both cases we are talking about the process of integration into some system or to solve a new problem.
The first stage of ingrowth causes stress and anxiety, in the second - a person at the beginning feels like a stranger, shows caution, and then begins to show interest and gradually gets used to and masters more and more of the surrounding reality. Sometimes this process turns out to be extremely difficult, but at the same time absolutely necessary for further existence.
