How Do Neurons Communicate? Explained easily

How do neurons communicate

Neurons are the nervous system’s building blocks. Signals are sent to different regions of the body and received. You must have read this kind of definition in your high school, but have you ever thought about how do neurons communicate? How do they transmit the information? If you are reading this article, then the sensation while dragging the mouse via your fingertips is also a message sent via a neuron.

Well, don’t worry, because, in the future, I will tell you how neurons communicate. So just read, connect, and explore. 

Basics About Neuro Transmission

Let us suppose that a person went for piercing. It will also be conveyed via the the neuron that you got piercing done.

There are billions of neurons in the mammalian nervous system. Neurons are electrically excitable cells that convey the nervous system pulses. But a connector called synapse among neurons could be discovered. Neurons are synapsed to communicate with each other. The mechanisms for conveying nerve signals could be used to determine two types of synapses. They are synapses and synapses of chemicals. 

Chemical synapses are the most common. It is through chemical messengers called neurotransmitters that nerve signals are sent. The nerve impulses are transferred via an ionic stream in electrical synapses.


A junction of two neurons is called a synapse. Moreover, it acts as a place for functional neuronal interaction, which helps transmit nerve impulses between neurons. Thus, synapses are discovered between 2 dendrites, dendrites/axons, or other neurons’ dendrites/cells.

How Do Neurons Communicate With Each Other?

Neurons convey nerve drives through the nerve drives or the potential for action formed on the axon plasma membrane. However, this action potential should be passed through the synapse to the second neuron to transfer the nerve impulse to the target. The synapse transmits the method nerve impulses is indeed different. Moreover, the two kinds of synapses convey different action potentials.

Synapse of Chemistry: Synaptic Transmission

Chemical synapses are the joints through which chemical signals convey action potentials. The majority of mammalian joints consist of chemical synapses. Moreover, there is a significant gap in chemical synapses called a synaptic cleft. The gap could be between 10 and 20 nm. Nerve pulse transmission by chemical synapses is carried out by chemical messengers called neurotransmitters. These neurotransmitters can be stored at the presynaptic membrane in synaptic vesicles.

When a potential action reaches, the terminal of the presynaptic neuron Ca2+ is activated to raise the Ca2+ cell stream in the presynaptic membrane. Ca2+ is usually higher outside the nerve cell concentration. The Ca2+ ions allow synaptic vesicles to be fused onto the presynaptic membrane and released into the neurotransmitter’s synaptic cave. Therefore, chemical synaptic transmission is the first answer to how do neurons communicate.

Synapse of Electricity: Synaptic Transmission

Electric synapses are the intersections where the action potential through an ion flow from a presynaptic to a postsynaptic neuron is conveyed. These are found primarily in lower vertebrates and invertebrates. 

You can also find them in the mammalian brain. Usually, electrical synapses convey nerve pulses more quickly than a chemical synapse. However, there may be no synaptic split or small synaptic split in electrical synapses. A gap connection forms an electrical synapse. The electrical synapse can also transmit nerve pulses in either direction. It is the second answer to the question of how do neurons communicate.

Final Words

Neurons are the nervous system’s building blocks. Signals are sent to different regions of the body and received. The answer to How do neurons communicate via synapse is by two methods. The first, Chemical synapse, and the second is the electrical synapse. Both the methods are the reason for neurons message transmission.
