The Five Senses: A Wee World Wonder

The five senses are everything you need to immerse yourself in the world around you. With the Wee World Wonders of sight, sound, taste, smell and touch, you have a full toolbox, a built-in navigation system at the ready.

SIGHT: Photo receptors in the part of your eye called the retina work like tiny projectors turning light into vision. Electrical nerve impulses add different shades and brightness. Whether seeing a baby or:  watching a fireworks display, the sense of sight has served you well.

SOUND: Sound is perceived through a series of vibrations. A network of little bones inside your
ear detect vibrations in the air and turn them into the electrical impulses; which tell your brain to hear what you know to be the sound of singing in the shower or dogs barking at the park.

TASTE: Taste is known as a chemical sense. The taste buds which are located on the tounge are capable of detecting 5 different and specific tastes; sweet, sour, bitter, salty and umami, which detects the Glutamate in artificial flavours. This is how you experience and enjoy the world with food.

SMELL: Smell is made up of a series of signals that work simultaneously in your olfactory system to enable your sense of smell.   300 receptors are all connected to different parts of the brain. When the receptors do their job correctly, you interpret it as fresh cut grass or a hot baking pie.

TOUCH: Activated by neural receptors located mainly in the skin, your sense of touch is a response to variations in pressure, these help to detect different types of physical contact. When you give a hug or have somebody hold your hand, that is the gift of touch.
