How do we experience daily l iving t hrough o ur s enses

1. How do we experience daily living through our senses Our Five Senses

2. Eye didn’t know that • Your eyes are composed of more than 2 million working parts • We all have microscopic creatures lurking in our eyelashes • The average person blinks 12 times per minute – about 10,000 blinks in an average day. • The older we are the less tears we produce. • Your eyes will never wear out. • The muscles that move the eye are the strongest in the body.

3. Eye didn’t know that • Only 1/6th of your eyeball is exposed to the outside world. • Your eyes begin to develop 2 weeks after conception. • Your eyes are always the same size from birth, but your nose and ears never stop growing.

4. Did you hear that? • The ear is an organ of hearing. There are three parts of the ear: Outer, Middle, and Inner Ear. Outer ear • The Outer Ear takes in sound waves that goes to the eardrum. • The outer ear also includes the auricle that collects sound wave 2.5 centimeters through the tube of auditory Meatus that enters the temporal bone. Middle Ear The part of middle ear is the eardrum. The ear drum is a semirasparent covered by a very thin layer of skin on the outer surface with a mucous membrane on its inner layer.

5. Did you hear that? • The eardrum is coned shaped with an oval margin and an apex as the coned surface.

6. Did you smell that? • Have you ever asked “Why do I smell what I smell”? • Well you do that because your nose is almost like a gigantic cave used to moisten, filter, and smell the air you breathe in. • As you breathe in, the air enters through your nostrils which contain tiny like hairs called cilia. • Cilia helps filter all kinds of things trying to enter your nose. • They also sweep all of the dirt from your nasal cavity.

7. Did you smell that? • Our nasal passage contains olfactory cells that are also none as nerve cells. • They respond chemically to molecules in the air. • Everyone has a different sense of smell something might smell good to someone and smell bad for the other.

8. How does that taste? • A single taste bud contains 50–100 taste cells representing all 5 taste sensations (so the classic textbook pictures showing separate taste areas on the tongue are wrong). • Taste receptor cells are connected, through an ATP-releasing synapse , to a sensory neuron  leading back to the brain. • Taste is the ability to respond to dissolved molecules and ions called tastants. Humans detect taste with taste receptor cells. These are clustered in taste buds. Each taste bud has a pore that opens out to the surface of the tongue enabling molecules and ions taken into the mouth to reach the receptor cells inside.

9. How does that taste? • We have almost 10,000 taste buds inside our mouths; even on the roofs of our mouths. • A single sensory neuron can be connected to several taste cells in each of several different taste buds.

10. How does that feel? • Touch is a sense that allows a individual to determine an objects shape, size, weight, texture, and temperature. • This is a sense that never turns off or takes a break. • There is many organs for touch, the largest organ for touch is your skin. • Threw out life people use there sense of touch to learn, protect the themselves from harm, relate to others, and experience pleasure.

11. How does that feel? • When you come into contact with objects you immediately. But feelings don’t come from your skin and muscles alone. It forms at the top of the brain, in a neatly organized sensory center that is linked with your body from head to toe.

12. Real life with Sight. • Say cheese. You’re taking a photo with your family. 1, 2, 3 click. Hey, what are these things in my eye? They’re floating everywhere but I can’t catch it. What is it? Your eyes are just trying to adjust to the light but it stunned your retina for a second instead. As that happened your pupils gets smaller because your eyes were absorbing all the light it possibly can. But when you in complete darkness your pupils are very large because your eyes don’t need to absorb basically any light.

13. Real life with sound. • Itsearly in the morning at 6:00, the alarm clock rings waking you for school. If it wasn’t for the sound waves flowing through the air entering your ear you would have never woke up and would be late for school. Or you can but like this if we couldn’t hear we would not know how to communicate with each other and learn stuff in school. You will also not hear alerts that can save your life in many ways. We use the sense of hearing everyday of our life, some examples are listening to the teacher speak, cars beeping to alert you, or just a friend telling a story.

14. Real life with smell. • You just got home from a soccer game and your mother was making dinner. You ask your mom “what smells so good?” she says I am making your favorite dish of macaroni and cheese. Your sense of smell is very strong and very powerful. You can smell something in a distance of 20 – 30 feet. Another example of smell is when you have a barbeque. The smoke from the grill travels in the air into your nose through little molecules. The sense of smell determines if the smell is bad or good.

15. Real life with touch. • It is a nice and hot summer day. So you and your family decides to go to the beach. The minute you get to the beach you run outside and step on the sand and say “OUCH” that’s really hot. This happens because your skin absorbs the hotness and sends the message to your nerve which sends it to the brain in less than seconds. Now this is where it gets cool. Did you know when you get sun burn it is considered as touch. This is why, the rays of light coming from the sun is so hot, it leaves a stinging mark on your skin. Then every time you touch that part of your skin it will hurt.

16. Real life with taste. • Your at a barbecue and you and your two friends get a cheese burger. You get a burger with mustard. One of your friends get ketchup and the other gets both. Your friend says you like mustard yuck! You say you like ketchup. Some people don’t like certain food but other people do. Other people have different taste than you. So one food may be good to you and it may be unpleasant to another person. That’s because all of your taste receptors differ from one another.
