cell communication

There are 3 ways of cell communication, no distance, short distance, and long distance. In a "No Distance" communication, to make a  signal transfer from one cell to another, we use the antigen presenting cell, when one cell sends signals to others.

 Local "Short Distance" signal is when you have multiple neurons connected to each other. The message is traveled in one direction until it reaches another neuron so neuron A and neuron B will release chemicals known as neurotransmitters that will allow the neuron signal cross acting kind of like a bridge. The bridge can have the option to block signals or allow them to pass.


 However, with "Long Distance" cell communication, a cell uses hormones to send signals to not only one cell but as many cells as possible. A growth hormone is an example of long distance cell communications, as the body grows growth hormone is spread throughout the body to every different muscles so they could receive the signals to tell them to grow
