Document Summary
Whether it"s unicellular or multi cellular, the objective is to collaborate, benefit from each other, promote growth and survival. They are more efficient to work together and in sync. Ex: the heart: if the cells in the heart beat differently, it is not good. In the heart, the communication path is direct through gap junctions. The mechanisms of communications are very well conserved. There are not a lot of changes in the how. The conserved mechanisms are essencial for: development, immunity, physiology, hormonal regulation and homeostasis and cell growth, survival and cancer. How do they interpret the request, which one takes priority, which one needs to be ignored In cell communication, the nature of the message needs to mean something. The signal molecules have to mean something to cells. The receptor on the cell surface or inside the cell is very important. Those diffrent cellular activities are all part of reaching a cellular response.
