Because reflexes permit faster responses without having to bypass several synapses.
Neurons would not be able to communicate across synapses. The different parts of the brain would not be able to communicate with each other as well.
Learning occurs in the cerebrum of the brain. Through a network of neurons, sensory information is transmitted by synapses along the neural pathway and stored temporarily in short-term memory, then neural pathways carry these memories to the structural core, where they are stored in long-term memories.
Your brain is the body part. It is the fatty, grey matter in your head, full of tissues, blood vessels, neurons and synapses. It is entirely physical. Your mind is not physical, it is made up of your thoughts, emotions, personality and desires. Your mind is thought to be a result of your brain, but it does not mean that they are the same thing. You can think of the brain as being the hardware of a computer. The mind is the program that runs on the computer. They are similar because they work together to produce consciousness and sentient thought.

They are neurotransmitters. They are sent across synapses from one nerve to another.
SSRIs increase the concentration of serotonin in the gap between the neuron synapses in certain part of the brain. This is the method of action of SSRIs, but WHY does this cause anti-depressant effect, it is still to be found.
Antidepressants work by increasing the quantity and action of all or some of the neurotransmitters, namely (1)serotonin, (2)dopamine, (3) norepinephrine at the synapses in brain in a person suffering from depression.
There is not just one chemical secreted into synapses (the gaps between neurons); instead, there are many chemicals secreted from the terminal buttons of neurons into the synapses. They are called "neurotransmitters."
MDMA, or ecstasy, affects three neurotransmitters: serotonin, dopamine, and norepinephrine. Studies show that MDMA can damage serotonin containing neurons. "Studies have shown that some heavy MDMA users experience long lasting confusion, depression, and selective impairment of working memory and attention processes."

The synapses take place in the spinal cord
There are synapses between each and every neuron in the entire nervous system; so yes, there are synapses in the peripheral section of the nervous system.
It increases the availability of serotonin in the synapses (spaces between nerve cells). However, THE CLAIM THAT PROZAC OR OTHER SSRI MEDS "CORRECT A CHEMICAL IMBALANCE IN YOUR BRAIN IS NOT PROVEN, NOT A THEORY, AND NEVER GOT PAST THEY HYPOTHESIS STAGE OF RESEARCH."
There are no reactions, the end of a nerve produces a gas that goes across the synapses and creates the electrical impulse on the other side of the synapses and continues the message!
