The Importance of the Neuronal Synapse

Summary

A neuronal synapse, also called synaptic junction, is the site of transmission of electric nerve impulses between two nerve cells (neurons) or between a neuron and a gland or muscle cell.

 A synaptic connection between a neuron and a muscle cell is called a neuromuscular junction . A functional synapse consists of three main components: the presynaptic element, which releases neurotransmitter chemicals into the synapse; the postsynaptic element, which receives these neurotransmitters; and the neurotransmitter itself, which transmits the impulse across the gap between elements and triggers an electric response in the recipient element.

What is a synapse?

A synapse is a small gap between two nerve cells, or neurons. There are many different types of synapses, and they all have different functions. All nerve cells have a long axon that transmits messages to other neurons and muscle cells. The axons at one end form a synapses with dendrites from other neurons or with muscle cells called motor neurons. The space between the two ends is called a synaptic cleft
.

What is the function of a synapse?

A synaptic connection between a neuron and a muscle cell is called a neuromuscular junction. A synapse is an area where there is a chemical or electrical connection, across which impulses can be passed from one cell to another. It was once believed that nerve impulses simply jumped from one neuron to another; however, with electron microscope examination it was discovered that there were gaps (synapses) between neurons. A neurotransmitter is released by the axon terminal at a synapse, which activates receptors on the postsynaptic membrane and transmits an impulse to the next neuron in line. Stimulation of these receptors causes ion channels in these cells to open, resulting in ion flow across the cell membrane.

How do synapses work?

Anatomy- The synapse is a small gap that exists between two nerve cells. On one side there is a presynaptic neuron and on the other side there is a postsynaptic neuron. The synaptic gap allows for a chemical or electrical signal to cross from one cell to another. 

Synapses are important because they allow communication between two cells. Without them, it would be impossible for information to flow from one neuron to another since neither cell could reach out and touch the other in order to transfer an electric impulse. 

In order for an impulse to be passed from one nerve cell (neuron) to another, chemicals must first be released by the presynaptic neuron into the synaptic gap so that they can bind with receptors on the postsynaptic membrane.

What are the types of synapses?

A synapse is where two neurons meet, and it's what allows information to be transmitted between them. There are actually three main types of synapses: chemical, electrical, and mixed. Chemical synapses use neurotransmitters to transmit signals from one neuron to another. Electrical synapses use voltage changes across the cells' membranes to pass on a signal, while mixed synapses use both chemical and electrical signals. 

Chemical synapses are important in headache management because acetylcholine is a major neurotransmitter that can cause headaches when there's too much activity at these receptors. When we eat foods high in tyramine (an amino acid), it causes an excess amount of dopamine which stimulates acetylcholine release and so more headaches are triggered than usual.

What happens if there is a problem with the synapses?

If there is a problem with the synapses, it can lead to a headache. The pain may come on suddenly and is often described as a throbbing or pounding feeling. 

Headaches caused by problems with the neuromuscular junction are often associated with difficulties in movement. Headaches caused by problems with the synaptic connections between neurons are more likely to be described as pressure, tightness, or dull pain. 

Other types of headaches related to this kind of malfunctioning connection include post-traumatic headaches that arise after an injury to the head, migraine headaches that result from disruption in the electrical signaling process within the brain tissue, cluster headaches that are caused by narrowing arteries which leads to severe discomfort around one eye. 

All of these issues can result from problems at the neuronal synapse which disrupts how cells talk and create messages through nerves.
