Improved cell communication

Cellular communication is an important process that allows cells to pass signals to one another. In this video lesson, you will be introduced to the process of cellular communication, identifying the three steps of cellular signaling in organisms. Cell-to-cell signaling is a critical component of coordinating cellular activities. Through this communication, messages are carried from signaling cells to receiving cells, also known as target cells. This signaling occurs with proteins and other types of signaling molecules. What kinds of processes and activities depend on cell communication? Just about everything you can imagine that happens in your body - growth and development, cellular reproduction, tissue repair, sensing pain, and much more. The pathway along which cellular communication occurs is called the signal transduction pathway . It's a series of cellular and molecular changes that help a target cell receive a message and respond accordingly. These pathways are cr...
