What is a Neuron?

Neurons, also known as nerve cells, are a unit of the nervous system.
Neurons have the job of receiving messages from the outside, weather
it’s a sound, or a type of food you eat, or a smell you smell or any other
external input from the outside. For example, if we take a horn sound
from a car, and the sound is heard, your neuron will hear that sound
and it will take the information and it will travel to the central nervous
system (the brain) which will make you react to the horn.

4. Parts and the functions of the Neuron
Dendrites: the branch-like structure connected to the soma. This is one of the three main parts of the Neuron. This is the place
where the neuron receives its pieces of information (external inputs) from another neuron, thanks to its receptors.

Cell body: (soma) is the core of the body. It is one of the three main parts of the Neuron. The function of this part of the
neuron is to provide nutrients for the neuron's energy source so that the role of the neuron will continue. The soma takes all of
the information given by the dendrites and puts it all together in an area, called the Axon hillock.

Axon hillock: is a strand connected to the soma. This part of the neuron is to keep and transfer the external input. Then, it will
be transferred to the next part of the neuron, the Axon.

Axon: is the axon hillock, but is covered with Myelin sheath.

Myelin sheath: this is a layer-type material that helps to prevent the signal from degrading.

Nerve ending: is the end of the neuron, this is what releases the external inputs out of the neuron

5. Nucleus: The soma contains the nucleus, which contains the genetic material of the cell

7. Step by step process
●The neuron receives its pieces of information (external inputs) from another neuron, thanks to their receptors


●The dendrites are the ones to collect this information and hand the chemical transmitters over to the soma


●After all of the external inputs gather up in the soma, all of the chemical transmitters (external inputs) will make their way
to the axon hillocks


●After all the chemical transmitters make their way to the axon hillock, they will move toward the axon


●The axon will transfer the information to the nerve ending safely, in a way where the information wouldn't get reduction


●After it reaches the nerve ending, it will exit the neuron and the chemical transmitters will make their way to a different
neuron until it reaches the central nervous system
