Hi this episode we discuss about the
0:03
body system that connects and
0:05
coordinates every step of the mind
0:07
and even the emotions we feel, namely the
0:10
nervous system anatomically divided
0:13
into two large groups of the central nervous system
0:15
consisting of the brain, the
0:18
brainstem, the trunk and the spinal cord,
0:21
this system functions as the
0:23
body's coordination center, then there is the
0:26
peripheral nervous system consisting of the
0:28
cranial nerves and spinal nerves that
0:30
function as a connection between the
0:32
center and the entire body, there is a
0:35
further classification subclass regarding the
0:37
peripheral nervous system which is divided
0:38
Based on how it works, namely autonomous
0:41
outside of human consciousness and somatic
0:43
or conscious which we will discuss in the next video
0:47
regarding the central nervous system, first
0:50
consisting of the brain
0:51
or the cool name for the brain, the brain is
0:54
found floating in the
0:57
human skull which is held by
0:59
cerebrospinal fluid When viewed from the
1:02
anterior, it consists of two parts
1:04
or what are called hemispheres which are
1:07
connected by a bridge called the
1:09
corpus callosum Looking closer,
1:12
this large part is called the cerebrum, the
1:15
outermost layer is the cortex which
1:18
consists of hills and valleys which
1:20
we call Cyrus and sulcus,
1:25
is divided into 4 large parts or lobes,
1:28
namely the frontal lobe, temporal lobe and
1:32
vital Oxy named according to the position of the
1:35
bone that protects it if it is split
1:38
in the median line or from the middle then
1:41
it will appear a structure consisting of
1:43
the cerebrum that we have discussed earlier
1:45
corpus if sum in the inferior that
1:48
connects the right and left hemispheres
1:50
then there is the encephalon which
1:54
consists of the thalamus and hypothalamus
1:57
then there is the brainstem or truncus
2:00
Enseval which consists of the cephalon machine
2:03
then there are Ponds and medulla oblongata
2:06
and cerebellum or small brain
2:11
brainstem if continued will come out
2:14
of the skull through a hole
2:16
that we call the foramen Magnum and will
2:19
continue to become the
2:21
spinal cord that will run through the
2:24
vertebrae from the neck to
2:31
well when passing through all
2:34
these vertebrae the spinal cord will
2:36
pass through a hole in the vertebrae
2:39
called the vertebral foramen
2:44
then the first peripheral nervous system
2:47
consists of cranial nerves, namely
2:49
peripheral nerves that come out of the cranium, there are
2:55
innervation to the cranium site coli or
2:57
neck, thorax, chest and abdomen, a total of
3:04
namely the factory of factory that is
3:07
responsible for us to be able to smell
3:10
then there is optics that function to
3:12
see oculo motor move the eyes
3:15
and many more Retro clear trigeminal
3:22
facus this which will later reach the abdomen
3:25
accessory and hypoglossal levels
3:32
there are so-called spinal nerves, namely
3:35
peripheral nerves that come out of the
3:38
spinal cord, the number is more, namely 31
3:41
pairs that provide innervation to parts of the
3:43
body according to their location, namely some
3:46
go to the neck or some are
3:49
called cervical there are 8 pairs C1 to
3:53
c8 then there are those to the chest called
3:56
thoracic there are T1 to t12 then there are
4:00
those in the lumbar L1 to L5 and
4:04
in the sacrum using S1 to S5 well
4:08
this provides requirements from
4:11
the neck until later to the most
4:13
inferior part of the body, yes, until the legs, there will be those
4:16
who innervate it Okay as a
4:19
summary today we have discussed
4:21
the anatomy of the human nervous system
4:23
which was previously from two, namely the center and the edge of the
4:26
center consists of the brain, the brainstem and the
4:28
spinal cord while the edge consists
4:30
of the cranial and spinal nerves like and
