0:13 [Music] senses
0:15 senses uhhuh
0:28 [Music] yummy
0:31 yummy
0:33 oh gosh be careful when you cross the
0:37 road did you notice your sense of sound
0:40 saved you from a major accident we have
0:44 five senses in our body the five senses
0:46 interpret the world around us as we can
0:49 find out and grasp whatever is happening
0:52 around us are you aware just now you
0:56 have used your five senses you used your
0:58 sense of sight while watching the pizza
1:01 shop your sense of taste was used while
1:04 having the chocolate bar our sense of
1:06 sound was used when you heard the car's
1:09 horn and became alert you remember when
1:12 you were hurt due to the stone at that
1:15 time you used your sense of
1:18 touch you were tempted by the smell from
1:22 the pizza shop it was your sense of
1:24 smell let's learn about our body parts
1:29 that help us use our senses before that
1:32 let's revisit the five senses once again
1:35 they are sense of sight sense of taste
1:39 sense of sound sense of touch and sense
1:43 of smell cool you look excited to learn
1:47 about it so we will first learn about
1:49 the sense of sight which part of your
1:51 body lets you read your favorite comic
1:54 book and check out the beautiful rainbow
1:56 outside which part lets you cry when you're
1:57 you're
2:00 upset yes r
2:04 eyes let's understand how our eyes work
2:06 rays of light enter the eyes through the
2:11 cornea pupil and lens these Rays pass
2:13 through a gel-like structure called
2:16 Vitus these rays are focused on the
2:20 retina in the center of the retina there
2:23 is the macula that provides us a fine
2:25 Vision the area of retina that surrounds
2:28 the macula gives us our side Vision or
2:30 peripheral vision
2:33 the retina converts the Rays into
2:35 signals that are set through the optic
2:38 nerves of the brain thus we are able to
2:41 see everything around
2:44 us you are a smart boy let's learn about
2:47 our sense of taste the organ that is
2:51 used for Taste is our tongue let's see
2:53 how it works on the surface of the
2:56 tongue there is pilli that look like
2:59 bumps these are the four types Philly
3:03 form foliate circumvallate and funky
3:05 form the taste buds are located on the
3:08 walls of pil they have the taste hairs
3:11 taste pores sensory cells and the nerve
3:15 fibers a flavor enters in The Taste pore
3:17 and sensory cells analyze the flavor and
3:19 send the information about it to the
3:22 nerve fibers they send the details to
3:25 the brain and thus we know the flavor
3:28 that we tasted now you know how you come
3:30 to know the flavor of your favorite ice
3:32 cream seems like you're having fun
3:34 learning this now let's learn about the
3:37 sense of sound the organ that is used to
3:41 sense sound is our ears let us first
3:43 understand the structure of ears look
3:46 closely this is the outer part of the
3:49 ear called PA the canal likee structure
3:52 is called the external auditory canal
3:56 here is a membrane known as an eardrum
3:59 there are three small bones the Anvil
4:02 hammer and sturup together it passes
4:06 vibrations to CIA a spiral-shaped fluid
4:08 filled in the ear it is lined with
4:11 psyllium which moves when it vibrates
4:14 this vibration creates nerve impulses
4:18 and thus we hear sounds now let's
4:20 understand how does our sense of touch
4:24 work we can feel hot and cold pain and
4:28 pressure all through our skin now look
4:31 closely the skin has many layers the
4:35 inner layer is known as dermis dermis
4:38 has so many nerve endings these nerves
4:40 can send and receive information into
4:42 the spinal cord and brain the spinal
4:45 cord in the brain tells us what to do
4:48 next touch is actually not a single
4:51 sensation it is a mixture of four
4:54 Sensations the sensation of cold the
4:57 sensation of warm the sensation of
4:58 pressure that alerts us if the layer is
5:01 smooth or or rough and The Sensation of
5:04 pain parts of our body like fingers lips
5:07 and nose have more nerve endings so they
5:13 sensitive now it's time to learn about
5:16 our sense of smell the organ which is
5:19 used for smell is our nose look closely
5:24 here at first a smell enters in our nose
5:26 there is mucus inside the nose where the
5:29 smell dissolves then they stimulate the
5:32 hair like endings of our allory receptor
5:34 cells this process generates a nerve
5:36 impulse which travels directly to our
5:38 brain the part of the brain that
5:41 processes smells is known as the lyic
5:45 system thus we smell things now you know
5:48 about the five senses of your body let's
5:50 review a few interesting facts about our
5:54 five senses our tongue can have 2,000 to
5:58 8,000 taste buds our ears have
6:02 approximately 20 24,000 sensory cells
6:04 the sturrup is the smallest bone in our
6:07 body that's in our ears our skin is the
6:09 largest organ we have because it covers
6:11 our whole
6:14 body I hope you like this video stay
6:17 tuned for more science videos and keep helping
