Five senses and how they work

There are no cones, rods or lenses. There are no tympanic membranes or miniscule bones.

Five senses and how they work

We use the five senses of sight, hearing, taste, touch, and smell to communicate When you see, light travels from an object and across the lens of your eye The ear has three parts - an outer, middle, and inner ear There are four different types of taste buds on the human tongue Sensory hairs identify odours and send messages about smells to the brain Introduction Humans use the five senses of sight, hearing, taste, touch, and smell to communicate.

It may seem like a simple process to see your friend or listen to someone talking, but there are many processes taking place inside the body to receive messages through the senses.

See image 1 Sight We communicate messages through sight by using visual signals that include facial expressions, gestures and posture or body language.

We receive these signals by using our sense of sight. When we look at something, light bounces off the object and onto the pupil in the eye. The light crosses the lens of the eye, the picture becomes focused, and then turns upside down.

The picture then shines on the retina, at the back of the eye. A retina contains rod cells and cone cells, which are both photoreceptors.

These cells let your eye see colours and details. The optic nerve sends a message of this picture to your brain, where the picture is turned the right way up.

Your brain then tells you what response you should make to the object that you can see. Your two eyes help you to judge distances and see much more than you would with just one eye.

Some people who cannot see short or long distances wear glasses or contact lenses to correct their vision. This is different from people who are partially not completely or completely blind because their vision cannot be fixed by wearing special glasses.

People who are blind may use a cane or guide dog to help them get around. Hearing The most common way for humans to communicate is by the sound made through speech. One person speaks and the other person receives the message by hearing it with their ears. The ear has three parts: Sounds reach the outer ear first, then travel into the ear canal and finally reach the eardrum.

The eardrum is a thin piece of tissue that separates the outer ear and the middle ear. There are three tiny bones in the middle ear that make sounds louder. Sounds from the middle ear travel to the inner ear, where they make tiny hairs inside the cochlea which looks like a snail move around.

The receptor cells then send signals along the auditory nerve to the brain.

The brain changes these signals back into meaningful sound that we can understand. See image 2 We have two ears because it helps us to tell which direction that sounds are coming from. People who cannot hear through their ears may be partially deaf, which means they still have some hearing, or completely deaf.

People may be born deaf or may have lost their hearing through an accident or illness. Taste We can communicate by receiving messages through taste. Babies make good use of communicating with their world by tasting things around them. Taste lets you enjoy the flavour of your favourite foods.

You can tell if food has gone off because it tastes unpleasant. Taste also tells you if something is dangerous or poisonous, although you should never taste anything if you think that it might be unsafe.

If you look carefully at your tongue you will see tiny little bumps all over it - these are called taste buds. There are four different types of taste buds on your tongue. At the front of your tongue you can taste sweet, on both sides of the tongue you taste sour, at the back you taste bitter, and all over your tongue you taste salty.

See image 3 Touch We communicate with touch by feeling things.For managers looking to learn about sensory stimuli, the new academic work reveals striking instances of senses’ affecting attitude, mood, and even memory more profoundly than words ever could.

A five senses (hearing, sight, touch, smell and taste) theme offers great ways for children to explore how well their five senses actually work. Here's some ideas to teach about the hearing sense. The senses of smell and taste work closely together. If you cannot smell something, you cannot taste it, either.

Taste buds on your tongue contain chemoreceptors that work in a similar fashion to the chemoreceptors in the nasal cavity. Unit 1 Using Our Senses to Observe Version 2 10/ 2 Objectives Children will identify the five senses (sight, touch, hearing, taste, and smell).

Transcript of Our Five Senses Work Together. Each of our senses has a specific job to do. We experience some things with only one of our five senses. You can hear music. You can see clouds. Most things, however, are experienced by two or more of our senses. For example, think about a thunderstorm.

You can see the lightning. What are the Five Senses and how do they function? SAVE CANCEL senses are touch smell see-because its easy for you to plombier-nemours.com have to start at small words then work up to big words.
