Neurons - Biology and Geology 3rd ESO
Hello students from CELTOFESO. I'm making this video to explain one of the most important parts of the nervous system, neurons.
00:00:01
Today we are talking about neurons, ok?
00:00:10
We studied neurons before because we said that they are very differentiated cells, so they are very different from other cells in our body.
00:00:13
So the shape of the neuron is very characteristic, ok? It's something like this.
00:00:24
and then with a very very long tail that finishes like this so here is the soma or the cell body
00:00:29
okay when we have the cytoplasm and organelles so remember the structure of cells that we study
00:00:41
at the beginning of the year the cytoplasm and the organelles are there okay then we have like this
00:00:50
little hairs or branches ramas that are called dendrites this long thing that
00:00:58
it's called the axon okay all this is called the axon and the axon is white
00:01:12
because it's surrounded by like a layer of like an envelope of a substance that
00:01:19
is white that it's called myelin and it's very very important so these are neurons okay
00:01:29
what is happening that neurons will connect with each other because the function of neurons
00:01:38
is connect we connect neurons to create thoughts to create memory to create responses so imagine
00:01:44
that I have this dendrite here that is connected with another the action of
00:01:54
another neuron okay this is the action of another neuron and then here we have
00:02:01
another neuron connected here and this neuron will connect its action to the
00:02:07
dendrite of the following neuron so here we have another neuron okay and it's a
00:02:14
more just because I want you to to focus on the on the structure and here between
00:02:20
the action of this neuron the the red neuron and the dendrites here is
00:02:28
happening a very important thing okay that just make it green and here we have
00:02:34
the synapses the synapses is the communication between neurons so neurons
00:02:45
are communicating with each other okay why because in the neurons we have
00:02:53
neurotransmitters we have substances that will travel they are in the action
00:03:00
okay and then they will travel to the dendrite of the next neuron and then
00:03:06
they'll create a new response okay so that is the synapses and that is the functions of neurotransmitters
00:03:12
and neurotransmitters are very different we will study some of them before but this is the main
00:03:18
part of of neurons okay
00:03:24
function as we saw at the beginning of the year they have dendrites from where they collect information
00:03:42
from other neurons and then they have the cell body where the organelles are cytoplasm and a
00:03:47
very long axon that sends the signals until it reaches the end of the axon and connects with
00:03:54
other neurons, that is, the neurons are connecting, they receive through the dendrites and send
00:04:02
send information through the axons and how they send information through
00:04:07
some chemical substances called neurotransmitters that are
00:04:11
very important between neurons there is a space called synapses and that is the
00:04:16
space in which these chemical molecules travel from one neuron to another
