biota friends Welcome to
0:04
Jonas school the last material chapter on the
0:07
sensory system Well finally we arrived Well in
0:10
this last material we
0:13
have previously studied our five sensory systems
0:15
starting from the introduction of the structure and
0:18
also the mechanism of each of
0:20
our sensory organs well in this 15th material we
0:24
will study the material regarding
0:26
disorders that occur in our sensory system
0:32
this sensory organ is a body organ that
0:36
can receive certain types of stimuli
0:38
well each person generally has five
0:41
sensory organs in their body The five
0:44
sensory organs are the sense of hearing sight taste touch
0:49
smell well these five sensory organs in
0:52
humans can experience disorders
0:54
and also abnormalities shop the factors that cause
0:57
disorders and diseases of the sensory organs in
0:59
humans are various well wood I
1:03
will give some examples of disorders
1:04
that occur in the sensory system
1:07
first we discuss disorders of the sense
1:10
of sight first well disorders
1:13
of the sense of sight for example
1:15
like the first Myopia or
1:17
nearsightedness well this is a disturbance in
1:20
vision that causes objects that
1:23
are far away to look blurry shop
1:25
but there is no problem if we
1:28
see objects that are close
1:32
six Yopi or nearsightedness This is
1:37
nearsightedness, which occurs when the light entering the
1:39
eye does not fall in the
1:42
proper place, namely the retina.
1:45
This condition is caused by the shape of the eyeball
1:47
which is longer than the
1:51
normal eyeball, so there is an abnormality in the eye,
1:53
especially in the lens. Then the second
1:57
is farsightedness or hypermetropia, this
2:01
is a disturbance in close-up vision,
2:03
so in hypermetropia sufferers,
2:06
distant objects are clearly visible,
2:08
but close objects are
2:14
This hypermetropia occurs because the light entering the
2:17
eye is not focused in the
2:19
proper place, namely the retina, but
2:22
is interrupted behind it. This is
2:25
caused by the eyeball being too
2:27
short or the shape of the cornea or lens of the
2:30
eye that is not normal, it doesn't work like that.
2:36
astigmatism, this is a
2:39
visual impairment caused by a defect
2:41
in the curvature of the lens or cornea.
2:44
This condition can cause
2:46
vision to become distorted or blurred.
2:50
Shop Hi, then there is night blindness,
2:54
this is a condition where there
2:56
is a significant decrease in visual acuity
3:02
dark environment, especially at
3:05
night. In the medical world,
3:08
night blindness is called NICA
3:11
lopia. Then there is cataract, this is
3:14
a disease when the lens of the eye becomes
3:17
cloudy or cloudy well in general
3:20
this cataract develops slowly
3:22
and initially the sufferer will not
3:25
feel disturbed but over time this
3:30
serious disease for vision
3:33
Hi then there is glaucoma well this is a
3:36
type of visual impairment characterized
3:38
by damage to the optic nerve
3:41
this damage is often caused by
3:43
high pressure in the eye well this condition
3:46
is characterized by pain in the eyes red
3:49
blurred vision as well as nausea and
3:52
nashob glaucoma this needs to be
3:54
treated immediately to prevent
3:56
blindness or total inability to
4:03
Hi well this is a condition where
4:05
our eyes are not able to see colors
4:07
normally this color blindness is divided into
4:11
two namely partial color blindness and also
4:13
total color blindness sufferers of
4:16
partial color blindness usually have difficulty
4:18
distinguishing only some colors while
4:21
total color blindness or
4:24
monochromic vision makes sufferers
4:26
unable to see colors at all
4:29
so that the world and various objects
4:31
around them will look
4:33
black or white only Well that's an
4:36
example of a disorder that occurs in the sense
4:39
of sight or eyes then
4:41
disorders that occur in the sense
4:43
of smell or nose well the first
4:46
is hyposmia this is a
4:49
partial loss of the ability of the sense of smell
4:51
to sense odors sub Hi but the
4:54
decrease in the ability to smell
4:56
is not means we are experiencing problems
4:59
with the nose only but this
5:02
can also be an impact of disorders of the brain
5:04
and nervous system of the body especially the
5:07
olfactory nerve which results in
5:10
our sense of smell becoming less
5:12
sensitive to existing odors then
5:15
anosmia well this is the loss of a
5:18
person's ability to smell
5:20
this condition can also eliminate the
5:22
sufferer's ability to taste
5:25
food soup well loss of the
5:28
sense of smell or anosmia can
5:31
affect a person's life besides
5:34
not being able to smell odors and also
5:36
taste food this condition can
5:38
trigger loss of appetite
5:40
weight loss malnutrition to depression
5:47
hyperhost Mia well this is a
5:50
smell disorder that can make the sense of smell
5:52
very sensitive to odors
5:55
this condition can sometimes be caused
5:57
by disease but there are times when heteros
6:00
Mia can appear without a clear cause
6:04
well next disorders of the sense of
6:06
touch or skin the first
6:09
furunculosis this is an abscess on the skin
6:12
that resembles a boil this is caused
6:15
by a bacterial infection namely the type of
6:19
then frenkel never-end this time often
6:22
affects forever on the hair and
6:25
also the surrounding tissue so it generally
6:28
appears on the hairy skin
6:31
Hi then there is skin cancer or melanoma
6:34
Well this occurs when cells which
6:36
produces melanin or melanocytes
6:39
undergo mutations or changes
6:41
as a result these cells grow
6:44
abnormally and uncontrollably so that
6:46
they develop into cancer well it is not yet
6:51
melanocytes to mutate and also develop
6:55
hi okay next is a disorder of the
6:58
sense of hearing or ear Okay the
7:00
first is otitis media this is an
7:03
infection disorder in the middle ear
7:05
precisely in the cavity behind the
7:10
this middle ear infection often arises
7:12
due to coughs colds flu or
7:15
previous allergies then there is also mastoiditis
7:20
this is a condition of infection in the
7:23
mastoid bone cavity and can also
7:26
be a complication or extension of the
7:33
long time shop well As for the
7:36
common cause of this disorder is from
7:38
bacteria then write this is a
7:41
disorder where a person cannot
7:43
hear sound partially or
7:45
completely in one or both
7:49
ears the causes of deafness vary
7:52
such as the buildup of dirt in the
7:54
fallopian tubes Hi damage to the
7:56
small bones behind the
7:59
eardrum fluid buildup due to
8:02
ear infections the effect of listening to
8:05
very loud sounds age or congenital from
8:08
birth well okay and lastly is a
8:11
disorder of the sense of taste or tongue
8:14
but before that for your information
8:17
should this channel have a content chapter
8:20
including school zone Jono animals
8:22
John Aquatic zone Jono's business zone plants
8:24
pet bio traveling zone
8:26
this channel is in the development stage
8:28
so it will be very valuable for us if
8:31
all biota friends help this channel
8:35
subscribing to this channel so please
8:42
disorders of the sense of taste or tongue
8:45
the first example is glossitis
8:48
well this is an inflammatory condition
8:50
that occurs on the tongue well although
8:53
most of it is mild glossitis
8:58
pain that can make it difficult to eat
9:03
glossitis results from infections from
9:05
bacteria and fungi which are more
9:08
common in people with
9:10
weak immune systems meanwhile
9:13
viral infections that often cause
9:15
glossitis are herpes which
9:20
then hypogeusia well this is a
9:24
decrease in the ability to taste
9:26
various flavors soup well someone who
9:28
experiences this disorder can still
9:31
taste the taste of food but
9:33
their sensitivity will be reduced and the
9:36
last is Egi age well this
9:38
is a condition where someone
9:40
cannot taste anything from the food
9:46
examples of disorders that occur in
9:48
our sensory system finally the
9:51
materials in this sensory system chapter are complete
9:54
Hopefully what I convey can be
9:57
digested, function and live for
9:59
all news friends don't forget to watch and
10:01
study the next material and
10:03
other learning videos so see you next
