This 3-D movie is a close look at some of the cell signaling and responses that take place throughout the body during the fight-or- flight response. The dynamic ways in which cells communicate with each other through molecular signals is depicted without focusing on anatomy, vocabulary or chemistry.

Like how does a cell know if its supposed to be a cell for the surface of our skin, a brain cell, a muscle cell, etc? What makes a new cell thats growing the middle of a muscle know that it’s supposed to be a muscle cell, rather than a dif type? Answer: Great question! It has everything to do with the signals cells receive from other cells and what stage of development you are talking about – embryo or human.
