All right then, let us start by
defining serotonin: This is a hormone found in the body and facilitates communication between
neurons or nerve cells in the body. These neurons are simply cells of the nervous system - a
system that carries nerve impulses between cells. You can say they transmit electrical signals
from one cell to the other.
These neurons continuously
communicate in between themselves so that our bodies are functioning properly. They regulate our
body processes. Imagine employees working together all day to make sure that operations of a
business are kept smooth all day long. This is basically what the cells or neurons do in our
bodies.
Now for them to be in touch
with each other, they need a neurotransmitter ((scientifically called 5-hydroxytryptamine or
5-HT), seretonin to make sure messages are transported to and from each of the cells. Much like
the workers would need an network (computers connected to each other) to be able to send
messages across and communicate.
Let's get our hands a bit dirty
here by reviewing the neurons or cells a bit. These are essentially joined by dendrites and
axons.
An axon is a nerve fiber that
is long and thin - it is a projection of a nerve cell, which conducts electrical impulses away
from the neurons's cells body or soma - by extension, they therefore take messages away from the
brain. Consider these the cables that make up the network in your office, they take away
information from the server. They are essentially the transmission lines of the nervous systems.
This means that as bundles collectively they make up what we call nerves.
Now dendrites on the other
hand, are basically the similar to axons. Their difference is that they receive signals from
other nerve cells and sends messages to the brain. In our example, it means these are the cables
that send messages or requests to the server.
These axons and denrites join
at a place called synapses (where the cables are joined together by plugs or at the computer
terminals) . This is the gap between nerve fibers or junctions through which cells of the
nervous system signal to one another and to non-neuronal cells such as muscles or glands. In
Short this is where the messages are sent across to the rest of the body.
Now, a neurotransmitter, which
is serotonin, is necessary to ensure that messages are taken from the brain through the axons to
the rest of the body and from the rest of the body by dendrites to the brain passing through the
synapses. In simpler terms, you can call serotonin, power that powers up the system. If the
system is powered up, everything goes well i.e. the body remains well
regulated.
It should now be clear why a
lack of serotonin could cause some discomforts. If seretonin levels are low, the body does not
function as expected. You may eventually fall into depression or become violent. This is because
the hormone or chemical affects behavior, thought and emotions.
In this website, we provide
some more information on the causes of level variations but to sum it up we can say that this
lack of serotoin may be caused by poor diet, stress, exposing your body to toxic substances.
Also, a change in hormone levels can cause a change in the level of serotonin. This is
especially true for woman during their premenstrual cycles.
If you have low levels or
serotoin then, you can act insensitively and fail to realize forthcoming danger or consequences
of your actions. The more you expose yourself to the conditions the more its production ( in the
brain) is reduced. Some of the know effects include, sexual problems like premature ejaculation,
depression, anxiety, personality disorders, Sleep disturbances, suicide, Impulsive acts of
violence and aggression, Obsessive-compulsive behavior, Alcoholism, Eating disorders and Perhaps
Alzheimer's disease and schizophrenia.
