hello everyone, in this video we are going to see together how neurons
look like function and what is so special about
them ready? so the first thing you need to know is
that neurons really like to socialize so they don't
live on their own but they live like a community in our
brain so the brain has 86 billions of neurons
and they're all interconnected with each others
and these connections is what builds up the neural circuits
that allow us to think communicate and move
so now let's go and see together how neurons look like
as all the cells of our body, also neurons
have a cell body and imagine that the cell body
is like a workshop where new parts of the neurons
get constructed or even repaired and is also where the dna
is located in the nucleus in the cell body
so then what is so special about neurons? well
neurons have two specialized structures the first one
that looks like antenna-like structures is called
the dendrites and the word dendrites derived from the greek
word dendron which means trees and indeed the dendrites look like
a little bit branches of a trees don't they?
why the second structure instead is called
the axon, which is usually one long protrusion that travels along our
brain or even body for example you have a neuron in your
spinal cord that extends this lung protrusion
- the axon that travel down your back along your leg and up to
the very tip of your toe how amazing is that, that one single axon
can travel that far within your body
okay let's go and see the individual functions
of these structures of a neuron so the dendrites
is the part of the neuron that is responsible to
receive the information from the other neurons
because you have to know something, dendrites are really curious!
so they are extremely curious they want to know
everything is going on in our brain and body
as all the curious people in your life once they get to know something
new they want to share this information with their closest friends
and so do neurons so when dendrites get the new information they get so
excited that they want to share this information
with the action with the of the same neurons so
imagine that the axon is like a telephone cable that carries this
information up to the very terminal and then once
the information arrives to the terminal it gets
transferred onto the dendrites of the next neurons
and this region of communication is called the synapse
and it's a very special region because it's made of
the axon terminal of the previous neuron and the dendrites of the next neurons
and so these two structures they are never
never touching each other's but they're very in close proximity
so how do they communicate that well i bet
each of you at least has played once in their life the chinese whispering
and so this is what neurons do they play the chinese whispering
all day long in our brains trying to communicate with each other
so they pass the information from the axon terminal onto the dendrites this is
how the message get transferred remember always in one
direction from the dendrites onto the axon and then from the axon
onto the dendrites of the next neuron and so on
thanks for watching and tagging along and see how a neuron look like
and if you have any more questions please don't hesitate to
ask me bye!
