There are up to 4 ways cells can communicate.
What are the 4 ways of communication and how does it happen?
1) Direct Contact
Cells can contact directly between a cell and an extracellular matrix.
What is the extracellular matrix?
It is a layer of protein between a nerve and a muscle.
2) Short range signals
The cells secrete a protein to communicate over a short distance and the other cell receives, recognizes and intereperets the secretes.
3) Long range signals
This method usually involves hormones. Hormones play a part in long-range cell communication. They play an active role in the development of a person during different stages of puberty. Hormones such as insulin control the metabolism of sugar in the body.
4) Through complex messages
This method is sent out in the form of electrical and chemical signals. These messages are usually between two neurons (are basic building blocks of the nervous system) or between a neuron and a muscle cell. The points at which electrical signals are converted into chemical signals and then back into electrical signals are called synapses which occurs in the brain.
Why is it important to know how cells communicate?
It is important as it is applied in our daily lives as cells depend on each other in multi-cellular organisms. They need communicate so that they know if they reproduction or growth needs to take place.They help our whole body stay alive and It does that by letting the body signal to the organ, so that a specific item or job can be carried to that organ so that its function can take place.
